Smith & Wesson Shield 9mm & .40 MagGuts™-High Capacity Magazine Conversion (+1)
Adds a round to your S&W Shield 9mm or .40 magazine without extension.
This is our third version of the Shield MagGuts™ conversion and it is better than ever!  We developed a revised ZeeSpring™ profile that adds just a little more spring force while compressing to a shorter height providing space for the new polymer follower.  The lock plate is now a robust stainless steel material with a brass locking block and is attached to the spring as one piece for simplicity and ease of assembly.  With the OEM-like follower and ZeeSpring™ combination you get an extra round in a super reliable magazine. The conversion uses your existing magazine tube and base plate while replacing all internal components with MagGuts™ parts. This conversion is compatible with both the 7 and 8 round 9mm magazines as well as the 6 & 7 round .40 magazines used in the original or 2.0 versions of the Shield.
-Easy to install.
-Adds a round while maintaining exact exterior size and feel.
-Extremely reliable feeding.
-Reliable slide lock operation.
-Compatible with original S&W magazines only.
-Compatible with Shield 9mm 7 and 8 round magazines (OEM only)
-Patented
-Compatible with Shield .40 6 & 7 round magazines (OEM only)

  1. Patrick G. (verified owner) –

    Nice product. Good support when I had questions. Would buy again

  2. Dennis M. (verified owner) –

    I installed these and at first they seemed hard but after loading and unloading they work great and its nice to know you have that extra

  3. NEILL M. (verified owner) –

    MY 7 and 8 rd mags are now 8 and 9 rds. Love them, over 500 rds and no malfunction.

  4. Samuel E. (verified owner) –

    Jams not reliable $50 down the drain.

  5. Josh D. (verified owner) –

    I got the +1 ZeeSpring extension for the M&P Shield 9mm. In the standard 7 round mag the follower and spring would come out of the top of the mag even when I wouldn’t touch it. Contacted MagGuts and they replaced it free of charge. Has been working flawlessly since

  6. Tom H. (verified owner) –

    Easy upgrade to increase capacity

  7. Jack G. (verified owner) –

    I have fired appx 150 rds with both +1 rd, then later with the +2. Would not sell them, now +2, for a profit. Plus many stars. More to come I bet. Good work.

  8. Jack O. (verified owner) –

    Works better than factory spring and adds a round. Very happy.

  9. David D. (verified owner) –

    I bought 2, one for my wife’s Ruger and one for my Shield. The instructions made the job a piece of cake (made the wife do her own). Tested them (500rds) both and they work great, +1 rd and the mags have no flaws. Will definitely buy more and refer to friends/family.

  10. Rodney w. (verified owner) –

    I hav bought 3 of these and they have been flawless.

  11. Martin C. (verified owner) –

    The MagGuts are a fine replacement – alternative for the original, problematic magazine springs of my 9MM MP Shield. I often recommend them.

  12. Kyle B. (verified owner) –

    Over 700 rounds and counting. Not a single malfunction. I carry a backup mag with MagGuts in it as well. Having 18 rounds on deck for a shield is CRAZY ( 1+8+9 ). Great buy

  13. Peter J. (verified owner) –

    At the range after emptying my OEM S&W clip, I tried to reload it and could only get a few round in it. I unloaded it and notices through the number holes that the spring was oriented wrong. Upon removing it, I found that it was bent at 90 degrees. Bending it back was useless as it would just bend again upon reloading it. I thought about calling S&W to get a replacement but I use this weapon as my daily carry and will never trust the OEM SPRINGS WITH MY LIFE. Then I found MagGuts. Not only is this a much better spring, but I also get an extra round as a bonus. You will not be disapointed if you purchase these.

  14. Mathew S. (verified owner) –

    Great product. Haven’t had any malfunctions yet. Highly recommended

  15. Richard F. (verified owner) –

    installation was easy. so far no problems. love added capacity. exactly what i needed. thanks for making this product.

  16. Jonathan C. (verified owner) –

    Great product

  17. Stephen A. (verified owner) –

    LCP and Shield products running fine.Waiting for LC9 and 45 Shield .Definitely will buy.

  18. Wayne M. (verified owner) –

    great item

  19. Edwin S. (verified owner) –

    Although it took several tries for the spring to settle properly, when it finally did, it worked well. I took my Shield to the range a few days later and had no issues with the modified mags.

  20. Larry S. (verified owner) –

    Works great took me about 5 minutes to install. Fyi the last round is a little hard to get in but once you do it works great. After shooting about 30 rounds loading was very easy.

  21. Jeff C. (verified owner) –

    Easy to install and better than the original!

  22. Nick H. (verified owner) –

    Great product, looks and performs great, made of high-quality material, way more durable than the OEM Smith & Wesson Springs. And you get to add one around here magazine. It doesn’t get much better!

  23. fred w. (verified owner) –

    sets up quickly, but I took them out of my M&P mag and went back to the factory originals so I wanted Mag guts to work, but could not get thru a magazine without a FTF

  24. Kevin D. (verified owner) –

    I replaced all 4 of my magazines for my M&P Shield and not disappointed with the extra room for one more round and how smooth the feed action.

  25. Larry J. (verified owner) –

    The three spring sets arrived quickly, were fairly easy to install, and function flawlessly as advertized. Good product!

  26. billy g. –

    Ordered the MagGuts parts to change my seven round magazine to eight rounds in my 9 mm shield. Perfect fit and the grip extension fits my hand and feels great. Love this product and highly recommend it. Thanks MagGuts!!!

  27. Kevin V. (verified owner) –

    Great product

  28. Chad T. (verified owner) –

    Easily add an extra round without adding any length to maintain concealment is truly awesome. Works flawlessly in my S&W Shield 9mm. Thanks again for a great product.

  29. Fego G. (verified owner) –

    Easy to install. It was a perfect fit. I haven’t taken it to the range yet so I can’t comment on how it will perform after a couple hundred round, but I’m sure it will exceed my expectations. If I don’t update this review assume everything went well!

  30. Bill E. (verified owner) –

    Worked well once I installed it properly. I did not understand that the first bend in z spring needs to be forward on the follower. When are you going to have a MagGuts +1 for the Kahr CM9?

  31. Arthur R. (verified owner) –

    This is the 2nd set of MagGuts I’ve ordered & they work great! I’ve never had a single issue them, no failure to feed or a single failure to fire! Good product that I recommend to everyone.

  32. Robert N. (verified owner) –

    I’ve got both the +2 and +1 options and both work perfectly. With zero additional length with the +1 and only a quarter of an inch with the +2 this is really the no brainer option.

  33. Ramiro D. (verified owner) –

    Excellent item.Well spent money. Highly recommended for Shield owners.

  34. Honor4thoseb4 (verified owner) –

    This is a great product and will in fact work with the Hyve +2 base plate. I just installed them together, now I have an 11 round mag:grin:

  35. Michael S. (verified owner) –

    Perfectly engineered for Shield 9mm. Exact tolerances for stock mag and MagGuts replacement spring plate. Not recommended for after market pinky extensions where the stock spring plate would be utilized.

  36. Michael K. (verified owner) –

    Good products, for a great price.

  37. Dan B. (verified owner) –

    This is the 3rd purchase of a MagGuts kit for me. My Shield is now an 8 +1 pistol with a 9-round backup mag, giving me an 18-round system. The kit installed easily and works perfectly. I really don’t understand why S&W doesn’t adopt this system itself.

  38. Dean P. (verified owner) –

    I have 2 other 9mm Shield MagGuts (+1) installed on other magazines. They work as advertised. This specific spring setup will not allow me to place the 8th round in my SW Shield Factory Magazine. Can you remedy this non-working product?

  39. Mike S. (verified owner) –

    Installed in a snap, very happy with the results. Mags work perfectly.

  40. Christopher S. (verified owner) –

    Works well and reliable

  41. John M. (verified owner) –

    Have installed on all my EDC 8 rd mags. I don’t use the 7 rd mags. Zero failures of any kind. Will install on any additional mags I acquire.

  42. Christopher H. (verified owner) –

    Has worked flawlessly with my M&P Shield. I am verry happy with this purchase an have recommended it to several other shooters already. I will be purchasing atleast 2 more.

  43. Douglas P. (verified owner) –

    I have it in my Shield9 and BG 380. Works perfectly!

  44. Marshall B. (verified owner) –

    I thought the spring was going to be flimsy from the images but it is very solid and quality made.

  45. Dana K. (verified owner) –

    Tried out the +1 springs in my Smith&Wesson Performance Center 9mm Shield installing in the 7 round magazine. Using Hornady Critical Defense ammo as well as Winchester White box I encountered no issues at all. I really like having that reliable extra round in the magazine for what I believe to be a reasonable price.

  46. Gerald H. (verified owner) –

    This is a great product to add another round and not change the length of mag. Easy to install. The slide always locks back after last round and feeds great. I wish MagGuts would update their website with the gen2 information and videos.

  47. Walt –

    Works great 100% reliable loads easier than factory thanks for shuch a great product, need a kit for 45 shield

  48. Mathew W. (verified owner) –

    Works good but only with factory base plate. Would be nice if it worked with hyve +1&+2

  49. Terry M. (verified owner) –

    This product lives up to my expectations. At the range last weekend ran 150 rounds through this magazine with no failures. Will be purchasing additional units.

  50. Guest (verified owner) –

    The magazine upgrade works great. You can tell the difference in weight though with just one extra bullet.

  51. Fausto A. (verified owner) –

    Product took a few times to get it to cycle correctly. But it does what it says it does. Would love a detailed video on new spring installation. Also the follower is sometimes a little finicky on placement.

  52. Mark E. (verified owner) –

    Would be a 5 but kinda spendy to add a single round, but overall worth the money for how well it worked and ease of installation.

  53. Joel S. (verified owner) –

    I purchased one of these a while back for my M&P Shield 9 flush fit mag just to test the reliability and long term function. It has never failed in the course of multiple range trips. I decided to get another one for my extended mag. Went to the range a few days ago and both functioned flawlessly. Now I carry my M&P Shield with 1 in the pipe, 8 in the flush fit mag and 9 in my spare extended mag. I feel good knowing I’ve 18 rounds of 9mm on me in a very small package.

  54. Bruce W. (verified owner) –

    First time use only so far. Failed slide lock on a few sets. Not sure what the issue is. Will keep on trying.

  55. Ronn H. (verified owner) –

    Works as advertised.

  56. Jeffery T. (verified owner) –

    Workes just as it’s supppsed to….

  57. David K. (verified owner) –

    They work great

  58. Adam A. (verified owner) –

    Solid. Functions Flawlessly.

  59. Ross L. (verified owner) –

    I also ordered the plus two round mag guts for my 7-round magazine

  60. Steve M. (verified owner) –

    Five Stars

  61. Robert J. (verified owner) –

    Thank you so much for shipping from Florida to California so fast! Ordered on the 18th, arrived on the 20th with Express shipping. As you might have guessed, it will be a Christmas gift. Ordered for my brothers M&P Shield 9. I know he will love his +1. Definitely ordering more MagGuts products after the holidays!

  62. Jeremy C. (verified owner) –

    I keep getting emails asking for a review. The product is fine but I hate the nagging emails. So here’s your review. Enjoy.

  63. Steve I. (verified owner) –

    I have used the +1 & the +2 in my shield magazines. They work just as advertised. I had a little trouble loading one the first time but after that first load they’ve all worked great.

  64. Stephen V. (verified owner) –

    Product works well, good customer service. will buy again.

  65. Michael S. (verified owner) –

    I bought a Magguts spring set for just one of my S&W Shield 8 round mags. I wanted to make sure it would work with the Fixxer mag extension. It worked perfectly, making it a 9 round mag now. Now that I know it works, I will be ordering the Magguts for the rest of my mags. Now I carry 9+1 and an extra 9 round mag!

  66. David G. (verified owner) –

    Extra round out of each mag always better could be the difference between life and death

  67. Paul F. (verified owner) –

    Easy to install, shot a hundred rounds worked excellent, thanks maguts!

  68. Jaime S. (verified owner) –

    Works great definitely buying more for my extra mags

  69. david r. (verified owner) –

    Work great. I love that they are metal and replace the plastic followers. Stuff at first but they function with 115/124/147 grain FMJ and FMJ

  70. Eric O. (verified owner) –

    I got these for a couple factory 8rd mags and they are very nice, a bit pricey though. Haven’t been to the range but I’m hoping they’re aren’t any issues.

  71. Shayler W. (verified owner) –

    This was a poor purchase and is a poor product. I tried installing this 4 or five times, and each time I would put rounds into it there was some sort of a malfunction. The first time there was a pop putting in Round 8 and the spring turned sideways inside the magazine. The next few times the follower would pop up and out of the top of the magazine, followed by the spring pushing up against it. Don’t waste your time.

  72. Roger K. (verified owner) –

    Not getting 9 in the 8 but am getting the full 8 where I could get only 7 in the 8 with OEM configuration. Also have to load the first round by hand. If using a loader, the top plate goes crooked if the loader tang presses directly on it. Smoother loading than with OEM spring. No problem, so far, with chamber feed reliability.

  73. Ed N. (verified owner) –

    The “z-spring” design works well. Easy to install and ready to be put to work at the range in no time. I have had no trouble with my magazines functioning properly!

  74. Esteban A. (verified owner) –

    Adds nothing but a Round. I prefer the bottom plate of the First Gen better than the silver tab. Other than that seems solid.

  75. Shawn S. (verified owner) –

    Love the +1 while keeping the stock mags. Well done!

  76. Heatherwheaton (verified owner) –

    Great product

  77. Milton B. (verified owner) –

    Great product, gun shot without a jam.

  78. Clint R. (verified owner) –

    Really like this product easy to install works great

  79. Dane V. (verified owner) –

    Works as advertised. Would purchase again.

  80. Amanda G. (verified owner) –

    The product is great and the shipping was fast, especially for the holidays. Would definitely order from them again.

  81. Mark M. (verified owner) –

    I bought two sets of mag guts for my S&W 9mm Shield 8 round mags. Pretty easy to assemble and I’m able to use 10 rounds per mag now. A little tight with 10 but they consistently work..

  82. Claire W. (verified owner) –

    Great

  83. Arthur D. (verified owner) –

    Works great! Shot 3 Mags work prefect

  84. Christopher A. (verified owner) –

    I installed in my 7rd Shield mag as well as one in my 8-rounder. Both installed pretty easily. During the first install (in my 8rd mag…which is now a 9-rounder!) the base plate slipped under pressure, which is when I realized that Magguts designed an ingenious little lip on the lock plate that came with the set. That little lip (once I installed it the way the instructions clearly indicated I should have in the first place) made it rock-solid. Then, during install in the 7-round mag (now an 8-rounder!), the pressure on the spring made it shoot up a couple of times. Make sure to wear EYE PROTECTION during installation!! Though I haven’t shot these mags yet, each of them are able to easily get one extra round loaded…as advertised. During the last round getting inserted, just the very first time loading them after installation, each one of them made a loud pop/click inside. I believe that had something to do with the spring interfacing with the bottom lock plate when put under ultimate pressure. No big deal, just something to expect as “normal”. I’d buy more!!

  85. Alberto V. (verified owner) –

    I’ve only shot using MagGuts a few times and it’s been working great so far.

  86. Julio F. (verified owner) –

    Great product. Easy installation. 300rds so far no issues

  87. Clint N. (verified owner) –

    It’s nice to be able to hold anothe round in a small capacity magazine and seems to feed good! I will be buying more.

  88. Terry R. (verified owner) –

    I love the extra capacity and ease of installation. Works great!

  89. Neal M. (verified owner) –

    Awesome product. Bought 3 +1 for my shield 9. Highly recommend.

  90. Valentin F. (verified owner) –

    No malfunctions, easier to load mags without ammo loader. Love it.

  91. Randall F. (verified owner) –

    Easily installed, but didn’t work right off, but once I got it working, it works flawlessly and really like the additonal one round in the pistol magazine!

  92. Elizabeth J. (verified owner) –

    Just had the opportunity to run 100 rounds through my newly remade magazines. No problems at all in defensive & competitive situations. I do wish the instructions on the packaging were more clear & had more diagrams. Once we watched a Youtube video it was easy.

  93. David S. (verified owner) –

    Put about 300 rounds through now 8 and 9 round magazines. They work great and I like having the extra round capacity.

  94. Martin A. (verified owner) –

    Plus 1 ZEE SPRING for MP SHIELD works better than factory. Great product and great people to deal with.

  95. David G. (verified owner) –

    Works as advertised. Highly recommend!

  96. Brandon H. (verified owner) –

    Recently odered 3 MagGuts +1 for my M&P Shield 9mm. One went in my 7 round magazine (now +8) I use for concealed carry. The other 2 went in my 8 round magazines with Hyve +2 extensions making them each +11. I use these as back ups or when I carry in my vehicle. Cycled roughly 200 rounds through the magazines with no failures. Couldn’t be more pleased with them.

  97. John C. (verified owner) –

    I was really looking forward to this product but in reality I find it to be very unreliable. Yes you can make it work but if you push down on the empty follower unevenly, you can pop it endways rendering the mag useless until disassembled and reassembled again. Any unreliability whatsoever is unacceptable with something I need to protect my life.

  98. Brandon G. (verified owner) –

    I love this setup.

  99. Frank E. (verified owner) –

    I now have Magguts for my S&W .380 Bodyguard and S&W 9mm Shield 2.0. Love both of them. Easy to assemble and works, works, works. Will purchase another for my S&W 9mm Shield 2.0. Thanks Magguts.

  100. Jeff F. (verified owner) –

    Very easy to install works perfect Super fast shipping Well worth your time and effort. Don’t wait do it now !

  101. Rodney C. (verified owner) –

    Purchased +1 springs for both 7 and 8 round magazines. Installation took less than 10 minutes for both. Have run about 75 rounds through each mag. Operation has been flawless. Three types of ball ammo and Federal HST 124g hollow points. Very happy with the purchase. Highly recommend.

  102. Tommy V. (verified owner) –

    Took to the range, no malfunctions

  103. Larry P. (verified owner) –

    The spacer plate that came with kit did not fit like the original plastic plate. When all together the heel plate would slide forward and could see new spring. Afraid with it not fitting the plate and spring would come loose.

  104. Joseph F. (verified owner) –

    Great product, works great. Had an issue with delivery from postal service. Contacted MagGuts customer service with questions concerning delivery and problem solved within a day. Delivery was delayed because of USPS issues, Jenny from CS resolved my concerns. Outstanding !!

  105. Mark M. (verified owner) –

    Sharp a hell when you install. Eye protection and gloves. Well worth it.

  106. Jordan R. (verified owner) –

    Easy to install, works great. Switch from USPS. We all know we can’t trust the government to run anything. The shipping was painfully slow. It took about 3 weeks from the time my product shipped to the time I got it.

  107. Brad H. (verified owner) –

    Excellent product

  108. Larry O. (verified owner) –

    I am not a handy man but I had no trouble install the new spring system in the magazine.

  109. Clifford P. (verified owner) –

    I put this is my flush magazine to hold more while having maximum conceal ability. Worked flawlessly through hundreds of rounds. Will be ordering more for my other mags.

  110. David A. (verified owner) –

    After installation in my S&W Shield 9mm, I went to the range for a test. Fired a little more than 50 rnds filling the magazine each time. Had no problems. Great product. I will be ordering another for my spare mag. and for other guns that I use for conceal carry.

  111. Raymond K. (verified owner) –

    I bought one kit for my S&W 9mm Shield 7 round magazine and one for the 8 round magazine. I now have an 8 rounder and a 9 rounder. The kit works as claimed and the slide locks back after the last round on both magazines A happy customer.

  112. Marc B. (verified owner) –

    Works as advertised, nice product, easy install.

  113. William K. (verified owner) –

    Yes

  114. Joseph N. (verified owner) –

    Received and installed two Magguts +1 kits in my S&W Shield 8 round magazines. Installation was easy and quick. I have run over 500 rounds of various ammo types both FMJ and JHP through the pistol with absolutely no failures of any kind. I couldn’t be more pleased.

  115. Ryan A. (verified owner) –

    Installation can be a tad tricky because you have to keep the spring aligned just right as you install it. Once you get past that part, the first time you load the mag it might seem like there isn’t room for the extra round because the edges of the sheet metal can catch a little extra friction toward the end of compression but it will get past that if you apply enough pressure. After that it seems to smooth out after a few uses. I’m very impressed with how reliable these have been. No failures at all after several hundred rounds.

  116. Stephen –

    Placed these in 3 of my shield magazines, 1 7rd and 2 8rd. Used my shield throughout a very rigorous training weekend with 1000+ rounds, with mags repeatedly in the dirt all day with ZERO malfunctions. Wouldn’t carry my shield without these.

  117. Mike G. (verified owner) –

    Got the spring that adds 1 round. The first time at the range with my so far flawless Shield 9mm. I had a few FTFs. The next time it worked 100 %. A few more times at the range with no more FTFs and I might jump it up to 5 stars but at the moment the trust just ain’t there.

  118. Kenneth k. (verified owner) –

    Functions fine, but If I push down on the back of the follower the front of the follower will tip out of the mag. The spring hasn’t come out yet, but I don’t try to induce this probability. After loading the first round the condition cannot occur. Otherwise I wouldn’t worry about it, it works and functions correctly.

  119. Nathan C. (verified owner) –

    Great product with no malfunctions to date!

  120. Ryan S. (verified owner) –

    Love the MagGuts, does not change the overall size of my magazine yet allows me to carry 9(+1) in my shield.

  121. Anthony D. (verified owner) –

    Finally got a chance to bring my Shield to the range and I couldn’t be happier with how well the gun fed with its new guts.

  122. Brett D. (verified owner) –

    Great product, very easy install, and very easy to load.

  123. Anibal M. (verified owner) –

    Awesome. Works reliably on my s&w shield. Please make for 1911 mags.

  124. Isaac J. (verified owner) –

    Product was received in a timely manner. Worked perfectly. No issues with FTF on S&W Shield 9mm.

  125. Lynn S. (verified owner) –

    Was easily installed and does great…

  126. William R. (verified owner) –

    I have installed and used the Shield MagGuts kits with great succcess. The LCP 2 version however was a different story. I had problems with the top follower getting out of position and hooking over the top of the mag. Also, my original baseplates would not engage the bottom spring button without enlarging the hole. But the biggest problem was that a fully loaded mag with the extra round was extremely difficult to latch in the gun. One of my mags wouldn’t latch even with extreme effort. I can’t imagine that it would cycle properly in this tight condition. So I returned my kits. Perhaps they will redesign it and I will try again.

  127. Anthony M. (verified owner) –

    Works great, will be ordering another

  128. Scott D. (verified owner) –

    So far so good! I’m really happy with my S&W shield +1

  129. Edward O. (verified owner) –

    Very pleased with purchase of 9mm Z spring ,going to purchase more . Hope you make them for 45 ACP soon.

  130. Stephen A. (verified owner) –

    Second one.First one worked great and so does the second.Adding one round to shorter mag is better for maintaining concealment in my opinion.

  131. Roderic R. (verified owner) –

    This product is the best thing on the market, I’m so please with the four i brought & i will most def put your product out there to my friends and others thanks one happy customer

  132. Thomas K. (verified owner) –

    Just what the doctor ordered! Easy install!

  133. Robert M. (verified owner) –

    I turned my small mag into my carry mag for low profile carry. I will install the kit in my 8+1 mags.

  134. James A. (verified owner) –

    The install was a little tougher than I expected due to the sharp edges in the spring. Otherwise works as intended.

  135. Gerald L. (verified owner) –

    Always a great and very reliable product

  136. Britt G. (verified owner) –

    Happy with my purchase, though in retrospect would have only gotten 1 for my shield 2.0 due to the +1 works great in the 7-round flush mag, but the 8 round (stock) mag is too tight to allow the +1 in the chamber. Essentially it means you can carry an 8+1 flush mag with a 9-round reload. If you carry the flush mag it works great. If you like the additional capacity of the 8-round extended mag as the one in the gun you don’t gain any additional rounds. The one extra in the mag is one you can’t carry in the chamber.

  137. Matthew H. (verified owner) –

    These are cheap for what they are, easy to install, and work flawlessly. I have 5 mags with magguts in them split between two different guns and have never had a malfunction. No one I know who uses magguts has ever had a malfunction because of them. I just wish someone would tell me if the lcp2 spring works in the lcp2 extended magazine, then I would have 6 mags with magguts.

    As a career Law Enforcement Officer who always carries off duty I can say this adds more capability to a great CCW platform. Adding a additional round per mag is crucial when you have limited ammunition in the weapon. I have 5 magazines with the +1 or +2 additions. All have functions flawlessly and let you seat your magazine easier than with a non modified magazine.

  139. Justin L. (verified owner) –

    Great product. Easy to install if you’re familiar with magazine disassembly. No failures of any kind after 150+ rounds. Will definitely be purchasing more kits for the rest of my Shield mags. Thanks Magguts!

  140. Ed J. (verified owner) –

    These spring were super easy to install in my glock 42 and m&p shield 9. Havent had any problems with them.

  141. Andy J. (verified owner) –

    These work well (even for .40 S&W/.357 Sig) but are too expensive. Wish they could drop the cost – they’d sell a lot more of them.

  144. Anthony H. (verified owner) –

    This product works as stated, installed in about 1 minute, and the mag still works like factory + 1 extra round. Even locks the slide back.

    I bought 2 kits for both of my 8 round M&P Shield 9MM mags and I’ve ran over 300 rounds through each one with zero malfunctions. They make a great and reliable product which I have recommended to several friends. Thank you and keep up the good work guys!!

  152. JEFFREY R. (verified owner) –

    Very satisfied with my purchase. Was easy too install and works really well. Nice to have the extra round in the magazine.

  153. Morvay (verified owner) –

    I also didn’t care too much for the spring setup and the bottom plate seemed sketchy on the +1 for the 7 round mag because the tab didn’t lock into the base plate like the factory setup does. I went with a different product from S.I. that I like better and it’s cheaper by a fair amount.

  154. Joseph T. (verified owner) –

    Ordered a couple of the +1 and +2 kits. Had a small glitch and support was great, fixed my issue right a way. These are quality pieces with top notch support, couldn’t ask for more!

    Install went smoothly. Just pay attention to the instructions and you’ll be golden.

    I am using MagGuts +1 springs in a Shield PC 9mm and a Shield PC 40S&W. I am very pleased with their service and have even noticed that in the 40S&W they feed more consistently and without hang ups that the factory follower and springs were experiencing! Can’t wait for the Shield 45ACP MagGuts to come out! Thanks for a great product.

  159. John H. (verified owner) –

    I purchased a +1 and +2 at the same time. I installed both according to the instructions. The +2 works as advertised but the +1 didn’t. Follower would tilt at front and it and spring would pop out of mag body. I returned +1 for a refund that was handled promptly and hassle free.

  160. Claude F. (verified owner) –

    a really great product , It does as said I got 1 extra round in my clip , My only problem will be if I ever chose to take it apart to maybe clean the clip it will be nearly impossible to take apart .

  161. William D. (verified owner) –

    I had a little trouble installing at first but watched youtube video and it worked great. took it to the range and ran a couple hundred round through it and had not one problem.

  162. David T. (verified owner) –

  164. Dan r. (verified owner) –

    Within 5 minutes of opening the package my shield had an extra round in the magazine. Shipping was pretty quick too. Will absolutely do business with them again. Highly recommended.

  165. Barry N. (verified owner) –

    I love carying my M&P shield 9mm. It’s very concealable. I used to carry a mid size M&P 40. But I wear slacks a lot and it was difficult to conceal my weapon. I made the decision to make my shield my EDC. However, the capacity was a concern. I’m an investigator and need to be ready for the unexpected. When I saw Magguts and their reviews. I couldn’t help but purchase the spring kit and follower for my two 8 round magazines. From 16 rounds I now carry 20 rounds. The expenditure of ammunition is something I honestly dont rely on, I’m a black belt win chun holder, a student of close quarter contact and a USPSA Shooter. But those 4 extra rounds and my skill level makes the world of difference! I have not had any failures 500 rounds through. Thank you Magguts!

  166. Zach S. (verified owner) –

    I was excited for this then installed it, I installed correctly from directions. Follower tilts in the mag. When shooting can’t get mag to lock back. I’m removing it immediately

  167. Patrick R. (verified owner) –

    Easy to install, looks good, works good.

  168. Philip L. (verified owner) –

    I held off on submitting a review until I had thoroughly tested them. They are super easy to install, and as reliable as anyone could hope for. I’m very happy with this, and would strongly recommend them. I happened to buy the Smith & Wesson Shield 9mm MagGuts:tm: (+1), but I’m confident these products will work flawlessly for any single stack gun-owner for which they are available. . I will be buying more as i expand my spare magazines.

  169. Don W. (verified owner) –

    I’ve used these before in other magazines and they work well. No problems.

  170. Daniel L. (verified owner) –

    This is my third set of orders for my M&P Shield 9mm. Everytime I buy more magazines for it, I buy another one of these magguts kits! Great product, fast shipping, and easy to install! Thank you so much!!!

  171. Frankie G. (verified owner) –

    Have an 8 round mag with a +1 extension so with the +1 spring should be able to hold 10rds but only holds 9

  172. Taylor H. (verified owner) –

    Installed in 7 and 8 rnd mag shot a bunch of rounds out of both and they work well . No malfunctions. They just work.

  173. Darrin C. (verified owner) –

    As I stated in the title, this is my second set of maggut kits. I ordered these +1 kits for the s&w shield 9mm that I purchased for him for his birthday last year. I already had a couple of the +1 kits that I installed in my shield 9mm mags a couple of years ago and they have functioned flawlessly. After shooting at the range with pop’s a couple of weeks ago, and watching him struggle loading the mags. I figured it was time to get a couple of more kits. Not only do they add an extra round per mag, but they make loading the shield mags much easier. So far everything that I have ever purchased from magguts has worked as advertised. I just wish that they would expand they’re product line to a couple of other semi auto pistols that I own. (Kahr cw9) That’s my only complaint.

  174. Danilo c. (verified owner) –

    I was actually impressed by the materials use and the design , fits perfect on a M&P Shield. Installation was easy, just make sure to fill the mag afterwards and then empty it before using on the gun, it allows the spring to set inside the mag.

  175. Carlos W. (verified owner) –

    They just work.

  176. Rito i. (verified owner) –

    I have purchased a number of magguts kits over the years and they are amazing! I love having the extra round without a magazine extension! Great quality and customer service!

  177. Ricky B. (verified owner) –

    I can get 8+1 now in my compact magazine and carry it and shoot it comfortably. Will get them for my other guns. Have shot about 100 rds so far and no issues. Will continue to put more rds through it.

  178. Tyler J. (verified owner) –

    Fit right in and got my extra round. Easy to do it, doesn’t seem to have any feed problems most like will buy more for all my mags.

  179. Michael E. (verified owner) –

    So far I’m impressed. Have only run about 100 rounds thru the 9 mm shield kits with out a hitch. I was thinking about getting a Sig 365 for the extra capacity but I like and shoot the shield so good. If the magguts continue to be reliable I’ll probably stick with the shield for my edc. I’m going to try some for my lcp2, having 1 or 2 extra rounds is a real game changer for me.

  180. Shawn M. (verified owner) –

    The shipping was relatively fast. And the new spring and follower work as advertised adding an extra round to the 7 round mag. After some range testing I feel confident using it in an edc roll.

  181. Jeffrey W. (verified owner) –

    Turned my 7 round factory magazine into an 8 round of exactly the same dimensions. The plus one would add one round to the factory 8 round without making it longer. The plus two does the same to factory mags, but I think it adds slightly to the length. Check out the website for details. I don’t understand why S&W doesn’t use this system on original equipment since it addresses the main issue with smaller guns: low round count. They make their kits for other guns but I can’t speak to how they work since I don’t own the other models.

    Great way to fix the issues with the spring collapsing issues the S&W Shield’s have. Plus you get an extra round.

  188. David Z. (verified owner) –

    Doing just what it says.

  189. Todd M. (verified owner) –

    I bought mag guts for both my 7 and 8 round magazines to try them out and I am very pleased. I see lots of people using extensions on their magazines and to me that defeats the purpose of buying an m&p shield. This keeps the guns stock size and adds a round. It’s great. Even works with a pierce pinkey extension.

  190. Douglas T. (verified owner) –

  193. Jim L. (verified owner) –

    I am giving this a 4 stars because this is only my initial impression. I am waiting for my long term experience before giving the last star. My initial impression is positive. I ordered one plus one and another plus two spring set for my M&P Shield. Changing out the internals was rather simple and straight forward if you have any experience or you are mechanically inclined. At first I was a bit concerned because the magazines loaded almost too easily. I was able to load 5 or 6 rounds simply with my fingers. In my experience new magazines have been more difficult to load until they have broken in. I wondered if they would have the force necessary to feed all rounds and lock the slide back after the last round. I loaded both magazines and took them to the range with 200 rounds for my first test. I must say I was pleasantly surprised. I fired all 100 rounds alternating between magazines with out a single malfunction. No failures to feed and no failures to lock the slide back on the last round. I have begun a long term test to see how the magazines, specifically the springs handle the pressure of being compressed over time. Since I bought them in July I will check them again in December around Christmas. If they pass that test I will check them again around July 4th next summer. Some test simply take time. I will check them with another 200 rounds then and if they perform as expected I will give them the final star.

  194. Samuel B. (verified owner) –

    I purchased two +1 magguts extensions for my M&P Shield and was able to test shoot them at the range. They functioned flawlessly and by virtue of their design are less likely to fold in on themselves and fail like one of my OEM magazine springs did. I plan to buy more in the future! Thanks for making such a stellar product.

  195. Aaron M. (verified owner) –

    Nicely designed and built solution. Functions flawlessly in my Shield 9.

  196. Tom D. (verified owner) –

    Easy to install and work great

  197. Jonathan E. (verified owner) –

    Installation was easy and I fully loaded (7 round mag, now 8 rds) and cycled snap caps through the magazine about 10 times without issues. First run of live fire, the magazine failed to feed the 8th round. Second run, the magazine did not engage the slide stop. From then on it functioned properly – I went through 100 rds total. This will need quite a bit more testing before I trust it with my life, but it does fit an extra round and perhaps just required a few runs through to completely break in.

  198. Robert d. (verified owner) –

    I bought this mostly toale it easier for my wife to load the mag. She does not use the +1 feature but it made it a lot easier to put a standard load out in the mag!

  200. Jerome J. (verified owner) –

    Follower is good, spring should have edges softened (cutting hazard), also did not give me an additional round on the 7 round magazine. Prompt delivery and seems to be a quality product.

    This product does just as advertised. However it is not compatible with the strike industries +2 extension for the m&p shield. It allows the follower to drop down below the magazine into the extension and get caught on the lip. It does work well with standard 7 & 8rd magazines.

    Easy installation and flawless function. Highly recommend

  217. Matt A. (verified owner) –

    I’ve been running Magguts springs in my Shield for a few years now. It’s a far better design than stock springs and the added capacity is always a bonus. You can’t go wrong with Magguts in your sidearm of choice.

  222. Curt J. (verified owner) –

    Previously purchased the two spring original design. Never had a problem, it’s a great product. I haven’t used the flat spring design yet and it appears to be an improvement but you need to do something to dull the sharp edges. I know you warn about it but it’s not likely people are going to put on leather gloves when handling the spring. I really wish you would take a look at improving the magazine capacity for the Springfield Armory XDS 45. It can be done. You would have a lot of sales for it.

  223. Nathan F. (verified owner) –

    I recently experienced a spring failure in my S&W Shield magazine and needed a replacement fast. I knew about Magguts and their reputation so I ordered their replacement spring. It came in 2 days before my Concealed Carry class, so naturally I didn’t have time to go to the range to check the function before the class. However, I did load and unload the magazine several times. It worked flawlessly. The extra round is a perk too. Incredibly easy to install. Magguts makes a great product.

  224. Keith D. (verified owner) –

  234. Gary S. (verified owner) –

    Both the spring and follower have extremely sharp edges. First time spring compression is tricky and finger cuts are likely. Once assembled correctly it seems to work ok…But, I have some reservations about its longevity.

  235. Mark S. (verified owner) –

    I was excited to find the two kits for the Shield magazines. I increased the small magazine by 1 and the large magazine by 2 rounds. The good: the kits function perfectly. I had an initial jam on the first round in the +2 kit, but after the first magazine, feeding was flawless. I’ve put tthrough about 10 full magazines with no issues. I definitely recommend these kits. The challenging: all the online instructions and videos are for the older kit with dual springs. The kits I bought came with the new flat spring. The instruction image in the box is really small but extremely important because the spring needs to be in the right direction. It’s also very sharp so be careful.

    Initially it took awhile to install, multiple tries. The springs were VERY difficult to install. If the springs do not set right it will not hold the additional rounds. With that being said once seated correctly it works! It fits the said amount and feeds through gun. I have yet to test it at the range. So I give it 4 stars because of difficulty and not actually testing it.

  280. Michael Heavey (verified owner) –

    I do note the baseplate only fits with oem base -the origional baseplate retainer fits into mag body,which allows for retension forward & back. perhaps a u-shaped baseplate w/dimple would work better –
    the top plate will shift & spring from top on first round loading if not very carefully loaded – otherwise functional –

  281. Ryan M. (verified owner) –

    Definitely a great and worthwhile mod for my carry mag to get an additional round capacity. With a little modification, works great with the NDZ Base Plate.

  282. eric C. (verified owner) –

  283. Alan R. (verified owner) –

    Assembly was pretty easy, except I didn’t get the inner plate hooked correctly on the mag body and had to redo it. Reading the directions may have prevented that, duh…. The metal follower makes it easy to load and a dozen full magazines thru the Shield are without issue. I won’t buy the kit for all my mags because of the cost, but for my primary 7 rounder with pinky extension it’s great.

    Easy to understand instructions, and simple installation. I still have to try it out at the range, but it loads all the cartridges +1, as advertised. The entire set-up seems well-engineered, as the spring is quite strong but more compact than the original. Yet, even with the additional round, it allows my magazine to insert without having to slam it home, or give it the that second tap to send it home, as was routine prior to the MagGuts mod. Well done!

  329. Steven F. (verified owner) –

    Installed it within 5 minutes of receiving the package with no issues. I packed my extended mag to 8 and and racked each bullet out without a single feeding issue. Still no problems to mention. A little bonus i found with this install that i didn’t foresee was that it added just a little bit more weight to the bottom of the gun (because of the extra bullet). In my personal experience it seems to offset some of the top-heavy nature of these compact single stacks and feels better in my hand. Recommended for sure.

  330. Joseph N. (verified owner) –

    I have never had an issue with any of MagGuts products. They work great! I just wish they would release their highly anticipated MagGuts for the Kahr 9mm seven round magazine.

  331. Peter E. (verified owner) –

    I haven’t shot my gun yet using the new spring system I purchased from MagGuts but installation was a complete nightmare. I suggest if you buy this product have it installed by a gun smith!

    I was pleasantly surprised how well this product worked. It’s very reliable and I tested 200 rounds through this magazine right after the install and it performed flawlessly.

  333. Anonymous (verified owner) –

    Works well, installation takes a few tries to get it just right. Worth the extra round? For 10$ more I could have got another 8 round mag but that’s the price we pay for concealability. All in all this product works as intended.

  334. George Z. (verified owner) –

    Order arrived in a timely manner, and installation was quick and easy…just follow directions and make sure spring is seated properly in the follower. Have put 350 rounds through my Shield with the Mag Guts and not a single malfunction. Would definitely purchase again!

    I bought 1 new version for my shield 9mm (I have 2 original versions) At least the new one actually pushes the slide-lock back lever in place better than original version that had issues with slide locking back when mag emptied from firing, but I’m having issues re-inserting with 8 rounds AFTER 1 is in the pipe with this version. I asked for 2 of these followers for my old versions to replace the metal follower but they’ve either never tried it, or they’re lying that you can’t just do that, and refused. I put this follower on the original and it works as well as the “new spring attached to the baseplate”. They want me to pay to send them back. I’m not giving mag guts another dime of my money.

  339. Kevin (verified owner) –

    Outstanding service and product! I highly recommend both.

  340. Paul Willis (verified owner) –

    I installed a MagGuts 7+1 kit into my M&P shield 9mm 7rd mag. I shot and reloaded 8 times without any hang ups.
    The only issue I had was when I unloaded the mag by hand. After clearing half the mag, the follower stopped pushing the remaining cartridges to the top of the mag – like the follower got hung up somehow. Lightly tapping the mag didn’t jar it lose. I turned the mag upside down and the rest of the shells just fell out.
    I tapped harder until the follower popped up to top of the mag.
    I tried unloading the mag again, this time without issues.

  341. Carlos (verified owner) –

    Works great

  342. Dominic M. (verified owner) –

    These springs are fantastic! .40 cal JHP and FMJ fed flawlessly every time and I certainly appreciate the added capacity!
    I did have problems with Ruger ARX Polycase ammo, experiencing failure to feed of the next to last round with both magazines. At 97 grains it could just be too light for the spring- and there’s also the palpable “lip” where the brass meets the bullet. Even my fingernail catches on it.
    Still- an outstanding product!!!

  343. marcel (verified owner) –

    Installation wasn’t too bad, it took a couple of attempts to get the spring seated properly in the bottom of the follower. Function tested with full magazine and 1 in the chamber, 9 times (81 rounds). 100% reliable.

    Probably the best additional capacity product on the planet. Never had a misdeed in over 2500 rounds with 2 different caliber pistols. Nice work MagGuts! Absolutely superb customer service too! Very fast shipping with easy transaction. My go-to for any magazine that needs extra capacity.

    I love the fact I can keep the same size on my 7 round mag and upgrade to 8 round with not having to sacrifice its external size, thats HUGE! I also got the +2 for my 8 round, yes it slightly increased the size but anything else that’s out there that increases by +2 is more bulkier. Hands down best mod increase out there that keeps your mag size small, home run for me.

    I just came back from the range where I tested my last GunMag purchase (a +1 gut for an 8-round mag for M&P Shield). It worked flawlessly, like the previous two. This is my third purchase from GunMag (a +2 and a +1) and I am completely satisfied. Easy to install, no feeding issues, purchase was easy and delivery was fast. What more could you ask for!

  464. James wright (verified owner) –

    The product did not work. There was no way I was getting one extra round in the mag after using the + 1 magguts’ kit. So not only did it not work which means it’s a faulty product but when I try to return it they’re trying to charge me for return shipping. Why should I pay return shipping on a faulty product??

    Both, the plus one and plus two appear to use the same spring length for the M&P Shield. Both work great in the 8 rd mag, nearly impossible to add the last round in the 7 rd mag. Perhaps making the spring shorter to fit better in the shorter magazine? Had no issues running both mags to full capacity.

  499. Phillip (verified owner) –

    I bought 3 and I liked those so much that several weeks later I bought 3 more.

    Didn’t quiet get 7 rounds on my 6 round M&P Shield 40, but can now at least get the mag to engage with a round in the chamber without having to beat it in. Which is what I wanted. No more mags dropping out the bottom of my carry gun!

    Worked like a dream but then I knew they would. Second order from MagGuts and super pleased with both

  507. Armando (verified owner) –

    I watched the video and it made the assembly look trivial. It wasn’t. Yet, after trying a few times I got it assembled into my 7 round magazine. Inserting the 8th round was a bit hard but I expected that. I tried loading and reloading with snap caps and it worked fine. When I took it to the range it worked as advertised. When inserting the magazine, I had to tap it in several times before it was flush. I think that the magazine springiness put more pressure than before. I gave this a 4 instead of a 5 because of this and because of the many times I had to try to install the spring. Overall I am very pleased with it. I already shot over 100 rounds through it with no problems. I went ahead and bought some more for my other magazines.

  508. Todd S. (verified owner) –

    I use the 7 rd mag for carry but use the Pearce pinky extension base plates. This may have caused the issues or it may not. I no longer have the stock base plate so no way to compare. With the MagGuts kit installed it would not hold 8 rounds, close but no go. Also the spring bottom plate is sized loosely and allows the pinky extension to slide forward on the mag significantly. Was hoping for better results but ultimately went back to stock spring and retainer plate.

  509. Armando (verified owner) –

    I am very happy with this product. Maybe it is because I had received one before and was familiar with its installation, but this time around it was a breeze. It works just as advertised. I experienced no loading issues nor jamming. I am very happy that it doesn’t add any extra length to my magazines. I highly recommend this.

    Does not work on the m&p 7 round mag. Impossible to put an 8th round in? I guess you are 50/50?

  512. Tyler T. (verified owner) –

    I got the new style spring and it does add the extra round on my 8 round, not my 7 round factory mag. But if I load it and walk around for any amount of time the follower will get stuck and all my bullets fall out. Useless for a carry gun, I can’t risk my life for one extra round. Wish it would have worked

    Was easy to install in my M&P Shield 40 6 round mags. Reduces the footprint of by only needing a pinky extension instead of the longer mag.

    Instead of 6+1 for daily carry now it’s 7+1 with the same footprint of the 6+1. I see this as a win win.

    Thank you MagGuts. Will buy more when needed and will tell friends and family that carry single stacks.

    Using MagGuts reliably for months in Shield Gen One, 8 rd magazines with +2 extension. Does add about 1/4” to length of grip which has not seemed overly significant in terms of better purchase on grip or concealment. But I decided to order a +1 to just see if slightly easier to conceal and still give me 10 (including one in chamber) in my first load. USPS in our area has spotty service at best with parcels often disappearing or being inexplicably delayed. I got my package and literally it looked like someone put it in parking lot and ran over it multiple times. Contacted MG, sent pics, and they immediately shipped out replacement…zero hassle. Can’t speak to reliability, conceal ability, etc of +1 yet, but customer service outstanding.

    This latest version is a big improvement. The molded follower runs smoothly in the magazine. A little fiddly to get installed with proper spring alignment, but got it on the second try. This is my third Magguts upgrade. Now I have 8 rounds in my short mag and 10 in the extended ones.

    Haven’t had a chance to shoot it yet but seems like a well made product. Hand fed a few magazines through it just to check function. Fed flawlessly and held open on last round.

  626. Anonymous (verified owner) –

    The product arrived before they said it would. It fit the extra round with the original base plate like it was supposed to. I haven’t gone to the range yet but I don’t anticipate any problems. Makes you wonder…if Magguts can do this why doesn’t the factory mag come this way? Makes a big difference with the original Shield. I feel more comfortable carrying with the shorter mag now as it conceals better with the same 8+1 as the larger mag.

    Magguts work pretty good for Glock 42/43 and they work excellent for the Sig P365x, but for the Shield magazine the spring was very difficult to install and would get tangled up inside the magazine. At one point while installing the spring, it came back out and cut my finger. So, be careful and wear leather gloves and eye protection when installing. I even tried to cut off part of the spring and install it so there would be less tension, but that didn’t work.

    I have consistently gotten what I paid for. I have equipped magazines for 4 of my pistols with their products. I have been completely satisfied with the function, reliability and ease of installation.

    This product was excellent. I had received my first set and it didn’t seem to fit properly so I informed them of my issue and they gladly took care of me. I am very pleased with their product and more importantly their customer service. Thank you very much.

    Great replacement, easy install, an extra round. Was also looking for a much softer spring to hand load. Could a leaf or two be cut? Yes it would void any warranty. Would it work? I’d like some feed back from your end. and thanks in advance.

    The spring was very easy to install and it works perfectly! It’s designed perfectly and the materials are better than original!

    Love this product. My first order with Magguts I had a problem with install, spring was giving me problems and follower got stuck. So I lost confidence and sent it back. Before sending back Magguts offered support but I declined, was just going to keep it factory I thought. They promptly refunded my purchase after receiving. After consideration I ordered again and first time install went in as smooth as factory components and function was perfect. Great company and customer service!

    Well unfortunately, these didn’t work for me. I ordered 5 of these and tried them in 4 different factory 7 rounders and 4 factory 8 rounders and a 7 rounders with the strike industries+2 extender on a 7 rounders and I couldn’t get in single extra round in any of my magazines. Hopefully I haven’t missed the return window as I had a long term family emergency happen followed by time in the field and just now got to try these out.

    Purchased these with a mag extension while trying to use stock mags and did not work. Once I loaded to 10 rounds spring shot out and dump the ammo. Cannot use unfortunately. So I’m sure a good product just not for me.

      That conversion will not work in combination with other aftermarket capacity adding bases. It will work perfectly along with factory S&W mag parts and will also work with aftermarket +0 pinky extensions.

    Hello l must say that I’m very disappointed in your product.i ordered two plus 1 extension for my shield. Just got around to installing them 1 one went perfectly. The other one spring is bent from the time I opened the package just would not seat at all in the follower no matter what I did obviously this was defective. For my first time ordering from mag guts. I am very displeased.

    I replaced the springs and followers in 4 S&W .40 Shield 7 round magazines. Loaded each magazine with 7 rounds and let them sit overnight. Went to the range the next day to test function. In the first magazine full of Corbon 135 grain JHPs I had one failure to extract, resulting in a jamb on the second shot. After clearing this I had another jamb on the sixth shot, I thought “Oh no, I’ve just wasted $100”.
    However, the next three magazines worked flawlessly, and I put the first magazine through two more 7 round cycles without a problem. So maybe something in that first magazine had a “kink” or something that straightened out after the first use. I appreciate the extra round in my Shield .40, and after another range session goes well, I might bump my rating to five stars.
    It is precisely made. I like the way the base plate snaps in place with a satisfying “click”, if you make sure you’ve got that little tongue on the spring base inside the magazine body, not outside like they caution you.

    One set (of 2) got jammed in the magazine base. The other has worked flawlessly through 100rds.

    Bought two of these as I was very excited but turned out to be bad quality. Watched many videos on how to install yet they broke and would not work.

    Great customer service and fast shipping, bent the spring the first time (i’m an idiot) and i emailed the company, they responded next day (monday) and i just installed my new spring free of charge (thursday). Very happy with it and happy with getting an extra round in my EDC. Thanks Corso! Will definitely shop again.

      We saw another review from you for another product. It sounds like something went wrong during assembly. The converted magazine should easily take those extra rounds and work perfectly reliably. Please refer to an email sent from support that will help you get this resolved.
