MagGuts™ for Glock 43-High Capacity Magazine Conversion

The result is a very simple, space efficient spring that collapses to a super compact height which allows space for that extra round while maintaining necessary force.

  1. Stephen E. (verified owner)

    All the reviews were spot on. The extension works very well!

  2. Juan c. (verified owner)

    Now I have 8 rounds in my Glock 43 magazine. Using a Pierce plus 1 and your maggots in the 6 round mag. For a total of 8 rounds plus 1 in the chamber.

  3. Cort T. (verified owner)

    Mags work grate, bought one for the SW Shield two yrs ago and it still locks open.

  4. Walter F. (verified owner)

    Glock 43 is 16% more populated. And, it’s fun to install the parts!

  5. Jordan R. (verified owner)

    0 issues. 7+1 capacity. It goes bang every time. Slide locks back every time on an empty mag. Easy to install, takes less than 1 minute if you can read directions.

  6. Hershel M. (verified owner)

    Great product. Works well in my glock 43.

  7. Robin D. (verified owner)

    I was so pleased with the MagGuts kit for my Glock 42, that I immediately ordered some more the day I bought a G43. MagGuts are easy to install, and a wonderful addition to any daily carry.

  8. Gary G. (verified owner)

    Great product

  9. Ranes (verified owner)

    GREAT stuff, really works!

  10. WILLIAM M. (verified owner)

    Excellent addition to the mags.

  11. Gary W. (verified owner)

    Outstanding product. All 43 owners take a look.

  12. Chris N. (verified owner)

    Converting a 6+1 to 7+1 is the right thing to do, and MagGuts does it very well. Great product!

  13. Robert N. (verified owner)

    Works fine. Be sure to wear leather gloves when installing into Mag. Spring ends are very sharp. Good product – recommend it!!

  14. Ross L. (verified owner)

    They work great in my glock 42 and they also work great in my glock 43

  15. Brad P. (verified owner)

    First off, the order process including shipping was fast and seamless! I’ve had the product for a week and half and have passed about 150rd through that magazine. Works flawless!! Definitely recommend

  16. Omri G. (verified owner)

    Great product. Need I say more?

  17. Greg S. (verified owner)

    the video looked straight forward and the premise looked good, but it was real work to be able to get 7 rounds in the magazine, which I was able to accomplish and it has run for the most part. a jam or 2, but 7 rounds is a tight fit.

  18. Richard T. (verified owner)

    Nothing like it when a product matches up to it’s billing. The MagGuts were easy to install and as promised, I could get another round in my single stack magazine. I promptly ordered another one for my other magazine. Love it!

  19. Sean Y. (verified owner)

    Retrofitted 3 magazines without trouble. Seem to work fine. Using 147 JHPs required some usage before they worked perfectly.

  20. Justin P. (verified owner)

    Added these to 2 of my G43 mags and I love them. Extra round with no added bulk in having an extension. Very reliable, have 500 + rounds through them and no issues.

  21. Paul G. (verified owner)

    Have magguts for both my shield and glock 43 and have had zero issues with either, highly recommend

  22. Brian H. (verified owner)

    I’ve spent time at the range with live hollow point ammo and at home with snap caps and have not had any FTFs or FTEs. I now use these for EDC. Great product.

  23. Guest (verified owner)

    Spring is great shot several hundred rounds no feed problems the only complaint is with the follower, it needs to contact the slide release a little better to allow the empty mag to drop away and they cut out just a little bit too much. It works just fine in glock Mags. But in after markets they don’t fall away smoothly all the time.

  24. Neil J. (verified owner)

    Great product, easy to install and performs as advertised. I’ve put about 200 rounds through my G43 with no problems. Nothing more to say.

  25. Kevin T. (verified owner)

    I like this item for the magazine I carry in my gun when I carry it in my ankle holster. It is the most concealable 7 round option available. It works flawlessly and was easy to install. I highly recommend it!

  26. James C. (verified owner)

    Got this for a glock 43. Had used other mag extenders but this product allows the mag capacity to increase without extending the size of the mag. Seems to be completely reliable after about 50 rounds so far.

  27. Shane B. (verified owner)

    Love my Magguts

  28. John B. (verified owner)

    Extended the magazine capacity by one. Works great thru 200 both hardball and HPs. Easy to install.

  29. Jim L. (verified owner)

    A small word of caution to future happy owners of these springs: I had to manually cycle my G43 about 20 full magazines worth before it slicked itself up. I THEN tested it at the range and am completely satisfied. I do suggest you cycle them and keep comparing the smoothness of their feeding before you trust them with your life. That said, I will be ordering for my other G43 mag, my XDs’, etc.

  30. Tyler S. (verified owner)

    +1. No bullshit.

  31. Reed D. (verified owner)

    Great product, time wil, tell how well the spring holds up

  32. Kevin F. (verified owner)

    These Magguts kits worked flawlessly!

  33. Greg G. (verified owner)

    Magguts has got a winner works flawless in my Glock 43.

  34. Ryan L. (verified owner)

    Great design, does exactly what the description explains. Easy install and no field issues.

  35. Coy P. (verified owner)

    This product performs exactly as advertised. This was my second purchase and I will be buying more in the near future. I plan to convert all my magazines to be able to carry the extra round.

  36. William S. (verified owner)

    250 Roads, no failures

  37. William S. (verified owner)

    as promised

  38. Adam Z. (verified owner)

    The mag guts product works as advertised. It is easy to install and performs flawlessly. I would recommend this product to anyone who would like to add an additional round to the stock magazine.

  39. Emily T. (verified owner)

    I got this for my brother-in-law and he likes it/it works well for his gun!

  40. Danny H. (verified owner)

    Simple and effective

  41. Christoph T. (verified owner)

    Top Product. Top Customer Service!!!!

  42. Matt B. (verified owner)

    Very easy installation. Final round is a little more difficult to load but not very bad. All rounds feed very well. Will absolutely be a returning customer. -MB

  43. Christopher H. (verified owner)

    Perfect alternative to add 1 without adding size.

  44. Roy i. (verified owner)

    Quite impressed with something so simple as a different style spring and follower to allow one to sneak an extra round in that compact magazine. Works without a hiccup. There’s even a guy on the YouTube that has figured out a life hack for a successful pairing of this product with the taran tactical +1 baseplate that doesn’t get hung up internally and will smoothly allow 8+1 in this little carry gem. Gonna be ordering another of these kits for a spare mag I bought along with the TTi plate.

  45. Joe C. (verified owner)

    I would love to right a review on this product! But I have received it yet I contacted magguts about my order and they told me to wait some more it’s been two weeks very disappointed

  46. Richard C. (verified owner)

    Simple product, simple installation, yet the result a significant difference for a small capacity CCW. Great product!

  47. Victoria G. (verified owner)

    Directions easy to follow, but had some difficulty inserting and keeping the spring down to put the cap on. It kept popping up and out, thus, giving me many small metal cuts on my fingers. But I put it in a vice to hold, and finished in 1 min then. I do get an extra 9mm bullet in the magazine and use the original base to carry with. A good product. Would recommend purchase.

  48. Greg G.

    Have test fired several different rounds and gave the magazine conversion heavy use as possible it is 100% reliable,You can stake your life on this magazine z spring and follower.

  49. Jeremy l. (verified owner)

    Simple: haven’t received my order yet. It’s taken almost a month to get my order and still not here. So my review is bad. I’m sure magguts is a solid company. But, their shipping is horrific. Get it together. Springs that probably weigh less than 1 ounce can’t seem to navigate the country in under a month. What is this, 1963? Jeez!

  50. Bill H. (verified owner)

    No problem with spring insertion. will store it and shoot it later

  51. John T. (verified owner)

    Replacing the OEM spring with a Magguts ‘flat’ spring was not too difficult and it gave me one additional round for my Glock43. Awesome.

  52. Chris T. (verified owner)

    Both run just fine. No malfunctions. Would buy again and recommend to a friend.

  53. Thomas B. (verified owner)

    I have a G43 and my son has a G43 and we both got the magguts spring in them and love them. I would highly recommend them to everyone.

  54. Gene W. (verified owner)

    This is the 3rd gun I have used the MagGuts components to add 1 round to the factory magazines. Like the others, it was easy to install ans works great!

  55. Michael H. (verified owner)

    Great product, but a little pricey. would recommend this mag spring.

  56. Edward R. (verified owner)

    The MagGuts parts appear to be well made and I like the overall concept, however I have chosen not to use the MagGuts spring unit in my G-43. I have tried several different styles and brands of magazine extensions & settled on the Pearce brand because it gives me a 7 round magazine. I was hoping that the MagGuts unit would work with the Pearce floor plate which it does not. I’m satisfied with seven rounds but I want the magazine to hold 8 rounds. When I’m at the range I unload my carry mag plus the round in the chamber and if the mag would hold 8 rounds I could put that extra round in the magazine instead of my pocket. MagGuts has a good idea and I hope they succeed. I also hope that they will make adaptations that will work with other brands of magazine extensions.

  57. Theodore L. (verified owner)

    Put magguts in. But got to many double feeds and jams

  58. Troy C. (verified owner)

    Great product, excellent quality and perfect operation. A welcome addition to a proven weapon system.

  59. Jamie K. (verified owner)

    Easy install, works perfect.

  60. nathan h (verified owner)

    I purchased 1 kit to see how well it fit and functioned and all I can say is I will be replaced all my G43 and Kahr P380 mag springs with Mag Guts kits. The G43 kit works perfect and the extra round fits without any extra pressure on the mag lips! 7 in the mag and 1 in the chamber and no problems with function! No extra drag do to pressure on the chambered round! As long as the springs holds up they will be worth the price of admission…

  61. Travis B. (verified owner)

    Works amazing and iv sent 300+rounds tho it with not one issue. Highly recommended!

  62. John F. (verified owner)

    I installed the MagGuts spring and follower in my Glock 43 mags. Although I had my doubts about them, they work flawlessly. I have put about 300 rounds downrange through 4 mags without a single failure. It’s great to have an extra round in your primary carry gun. I liked them so much, I bought 2 for my son’s G43.

  63. Robert Q. (verified owner)

    I have 2 stock mags with MagGuts Z spring and couldn’t be happier 6 plus 1 to 7 plus 1 without compromise to concealabity no extension at base of grip like your quote the last round is on you and that’s the beauty of the flat Z Spring :flag-us::flag-us::thumbsup: perfect capacity upgrade for a Glock 43 or 42

  64. Brandon C. (verified owner)

    Spring required a bit of break in before I could fit seven rounds in the magazine, but once broken in it works as advertised and has been 100% reliable over the course of a couple range trips and approximately 150 rounds fired. Would recommend and would definitely buy again.

  65. Stephen A. (verified owner)

    Works great to add an extra round to a woefully under capacity magazine.Glock could have done better.Absolutely reliable feed and slide hold open on both that I own and have tested extensively.

  66. Adam W. (verified owner)

    A little difficult to install but no biggie. Tension on spring is too great for proper feed. Gun jammed frequently. Ammo was top quality by multiple manufacturers. Reinstalled factory spring. Gun runs great.Spring needs to be tweaked for proper function

  67. Brett M. (verified owner)

    Awesome product!!! Went to the range today,no problem at all 100 rounds. Love that I get more rounds with out changing the size of my magazines and the size of the firearm for CC. I would recommend this product. Thanks

  68. Chris M. (verified owner)

    I wanted to be able to carry this mag as a spare. At the range it worked well. However, i noticed that while loading the mag, the follower would tip up and stick out of the top of the mag. Concerned that over time it would be able to come completely out and cause a malfunction. I am unable to replicate this malfunction with either glock factory mags or maggutz kit.

  69. Darren L. (verified owner)

    Great product, works great, not too hard to install, fast shipping, great price. I’m very satisfied.

  70. Erichson L. (verified owner)

    reliable extra 1 round perfect glock!

  71. Alexander S. (verified owner)

    Like all the product these functioned flawlessly.

  72. Christopher W. (verified owner)

    Fast shipping. Item as described.

  73. Collin S. (verified owner)

    Works flawlessly with my Glock 43:copyright:. I have never had failures of any kind with them and have put over 1000 rounds through both magazines (both with maguts).

  74. Harry S. (verified owner)

    I have 3 M&P springs for 9mm. two work ok and the third will not let me get the eight round in. How do i fix the problem?

  75. Gary W. (verified owner)

    I got a few MagGuts for my Glock 43 after already having great success with their LCP II product. I have to say I’m equally impressed. Installation was easy and they’ve been working well. I’ve put about 100 rounds through the four G43 magazines that I modified. Not one failure to feed. I highly recommend MagGuts, they’ve been flawless for me.

  76. Dean D. (verified owner)

    An extra round of capacity with no downside? It’s pretty much a no-brainer. MagGuts work! After installing a MagGuts spring, I’ve shot hundreds of rounds from my Glock G43 with no issues at all. I wanted to truly test it before giving this review. MagGuts is such a simple solution as well. No machine work necessary. Not to mention, if you sell the firearm you can easily put the factory spring back in.

  77. Tim G. (verified owner)

    the spring and follower replacements work well in the G43 mags and the G42 as well. I’ve been using them for about 7 months and have run several hundred rounds through each with -0- failures of any kind. If you want to add an extra round without changing the dimensions of the magazine then this is your fix.

  78. James D. (verified owner)

    Great spring and follower. It does what it says without a hitch.

  79. Alan N. (verified owner)

    Glock 43 with the Magguts installed and fed it 115gr FMJ, 124+p JHP, 147 XTP JHP. Hit ate over 150 rounds of each without any malfunctions. The slide locked back on last round every time. Good product and would recommend to anyone. Thanks, Magguts PaPaGrizz

  80. Kevin B. (verified owner)

    I am extremely pleased with my magguts z-spring. So happy in fact I’ll be buying a few more soon. What a well thought out product and a must have for those of you that carry a G43. Add a round to all your mags with this 5 star product!!! Zero malfunction with my first 250 rounds No FTF or FTE at all. Mic drop :microphone:!

  81. Greg (verified owner)

    I admit I was worried using this for my EDC. For the last year, I have kept one fully loaded in my G-43 and 3 in my range bag that got fired about once a week. Have never had an issue with the 3 from the range, and today I emptied my carry ammo at the range with no failures. It’s been a year. Yes I trust them.

  82. Chapman (verified owner)

    Everything is normal cycling through the mag by hand, have not shot gun since installation

  83. John V. (verified owner)

    I have used MagGuts kits in all my single stacks; M&P Shields 9, 40 S&W, and a G42. So when I recently got a G43, I quickly ordered 2 kits for it. They were simple to install, though I have not yet made it to the range to test function? I just wish a kit for the Shield 45 would be made available, although I have been told by MagGuts that it’s “in development“.

  84. Fusch B. (verified owner)

    Easy to install (hardest part was getting the mag base off). So far put 200 rounds without any problems. Very pleased, I would recommend.

  85. Martin P. (verified owner)

    Good to have, hopefully I will never need the extra round. Still a nice addition on the range or for practicing.

  86. Javier G. (verified owner)

    Great and easy way to up the capacity on the factory mag,runs flawlessly have had no issues,I highly recommend their products,I also have the Magguts on my bodyguard 380 with the same results

  87. James S. (verified owner)

    Always good to have the extra round, for an extreme self defense action. Not always easy the conceal carry a pistol with an extended magazine. Only concern I have is the follower come very close to flipping out of the mag. Time will tell…

  88. Leslie C. (verified owner)

    wonderful cust services, astonishing quality

  89. Edward S. (verified owner)

    The price was right and they worked with a Fab Defense +4 extension even though you said they weren’t compatible with extension devices, but I’m sure you haven’t tried every one made. Needless to say I’m happier than a pig in his own excrement! LOL! I’m headed to your site to purchase a couple more right now! THANKS MAGGUTS!!!

  90. Sol Y. (verified owner)

    My Glock 43 magazine runs smoothly with the magguts upgrade. Simple to install.

  91. Al S. (verified owner)

    I’ve had it installed for a few weeks on my 43. I’ve put several hundred rounds of different brands of ammo. Including my defense ammo without any failures. It works as advertised.

  92. Angel R. (verified owner)

    Best way to get that plus one and still keep my G43 extremely concealed with flush magazine!!! Ran it hard at the range with no failures!! My second one and I’m sure it won’t be my last!! Fast shipping and quality product!!

  93. Craig E. (verified owner)


  94. Ryan M. (verified owner)

  95. Jason M. (verified owner)

  96. Duane W. (verified owner)

    Reasonably priced, reliable function, a great addition to your Glock.

  97. James G. (verified owner)

    Fantastic product and great company.

  98. Matt J. (verified owner)

    This is one of the revolutionary products I’ve seen hit the pistol market and it works! I have one for my Ruger LC9s also with 100% reliability. I’m a smaller guy so big extensions don’t work for me, it makes me like my Glock 43 even more.

  99. David L. (verified owner)

    So it appears to be a well made fairly well thought out product. That being said I can not trust my life to it. Fmj never gave it an issue always feed after a 1000 rounds of fmj not an issue. Now to the problem… hollow points the round that you would be carrying in a self defense situation not as reliable. Regular 115 grain basic hollow points were fine. 147 grains gave me the most issues out of every box of 50 3-5 on average would fail to feed. Followed by any hollow point regardless of grains that had a little rubber tip. Simmilar results 3 on average out of every 50 would fail to feed. This in my opinion is something I couldn’t live with in a self defense situation. Were the mag I use could fail at the time of crisis. Magguts you are on to something good here please look at these issues. Which after a quick google search seem to be fairly common. And figure out what you need to do to make it work 100% all the time. I will only use it as a range mag at this time. Hope this helps anyone else trying to make a decision. If nothing else please test one of these with the ammo you intend to use to ensure it works reliably.. don’t just stick it in there an never check you are putting yourself in a bad situation.

  100. Eric B. (verified owner)

    Magguts changed the spring design in order to prevent you from using their product with another +1 so you can get +2. Don’t know why they have this attitude problem, but will never buy another one of their products because of this attitude.

  101. Bruce A. (verified owner)

    Simply put, they work great, added capacity without any added bulk. My experience with 8 magazines has been 100% RELIABILITY & several hundred rounds down range:wink::wink::wink:

  102. Joseph M. (verified owner)

    Easy to install and fits the extra round without difficulty. Flawless function so far. Will be getting more!

  103. Mark H. (verified owner)

    Hard to put together and does not increase round capacity.

  104. Aaron H. (verified owner)

    I got a coiled spring which i know is not the one they made for the g43. The follower jiggles around. Obviously they’re not very organized. Dont purchase from them. You’ll get the wrong product.

  105. John S. (verified owner)

    Love MagGuts! When are you guys going to make springs for extended baseplates like the extremely popular ones from Taran Tactical? +1 or +2 baseplate with +1 MagGuts? Come on guys, let’s make this happen!

  106. Jerry M. (verified owner)

    very easy to install and works great

  107. Michael B. (verified owner)

    It’s a little hard to get that last round into the mag, but there aren’t any feed issues so far. I wish I could get one that fit into my ruger factory issued lcp2 extended mags. Bring the +1 capacity up to +2 or +3. Works great in my Glock 43 though.

  108. Justin B. (verified owner)

    Have used these in Glocks, Shields, and Bodyguards and never had an issue. They work as advertised.

  109. Ryan W. (verified owner)

    Product seems to be high quality. I’ve been using this on my G43 mags for a couple months now and have had zero malfunctions. Product does what the description says.

  110. Robbie M. (verified owner)

    Works great, with the mag guys on the pinky extension. Glock 43. No need for my shield now. My opinion at least

  111. Paul G. (verified owner)

    Installed the magguts in 3 glock 43 mags. So far put 400 rounds of tulammo, sig performance, imi hollow points and some hornaday critical defense and have had no failures. Great addition for my carry gun. Also have them in the wifes 42 no issues.

  112. Justin M. (verified owner)

    Used MagGuts on my P380 and they are great. This is my first experience with the “Z” spring. It works as advertised. Bullets can nose-down easier while loading vs. the stock setup. Also it’s louder – the spring scapes against the mag walls, unlike stock.

  113. Robert C. (verified owner)

    Shipment is quick and the product is top notch. I have purchased 12 of them so far perfect functionality. Installation is easy. I highly recommend.

  114. Eliseo A. (verified owner)

    Great product. Very reliable.

  115. Dereck b. (verified owner)

    These work well as prescribed, I only wish there were a longer spring that would allow it’s use in conjunction with the +2(for +3 total) extended floor plate..

  116. Tim S. (verified owner)

    Excellent product. I would love to see a higher round count for the extended Glock 43 after market mags.

  117. Will M. (verified owner)

    This was my 2nd set of MagGuts. I had previously purchased them for a Glock 42. This product functions perfectly and performs exactly as advertised. The follower looks more professional than the stock follower.

  118. Jeff B. (verified owner)

    Works great, easy to install. I had one for my shield, and now have 2 for my glock43. I Will deffinatly buy more as I get more magazines.

  119. Paul H. (verified owner)

    I have used these in 2 guns, Glock 42 and 43. This is a must do up grade. It works so we’ll and is so dependable I wonder why Glock doesn’t OEM these systems in all Glock single stacks.

  120. Benjamin B. (verified owner)

    Amazing product, needs to be better publicized!!!

  121. Arnold C. (verified owner)

    an extra round without a longer magazine. Fantastic. Any other magazine being planned?

  122. Jon B. (verified owner)

    Just bought my second spring for second carry magazine, excellent product and works as expected. Nice to have extra capacity for very little cost. Well made.

  123. Daniel K. (verified owner)

    Works great

  124. Michael K. (verified owner)

    As always total reliability with this product

  125. William R. (verified owner)

    Works Great, make sure to look at spring orientation.

  126. Marc D. (verified owner)

    Fits perf and the quality is a1

  127. Nathaniel C. (verified owner)

    Has worked for 50-100 rounds. Easy to load the factory 6 Rd mag with now a 7th round without excessive last round tension. I expect it will function reliably with thousands of rounds – though I had not been able to find a review of “thousands-of-rounds-reliability” prior to purchase.

  128. Joseph M. (verified owner)

    Had two of these for the g42 that ran flawless so I purchased some for the g43. Never any stoppages/ failures to feed and always locks back. 0 issues with these things and recommend them to everyone; buy with confidence

  129. Nicholas D. (verified owner)

    Installed these in just minutes. Instructions were very clear, and they functioned flawlessly.

  130. Michael D. (verified owner)

    I purchased the magguts glock 43 extra round kit because I wanted more capacity without increasing length of grip. To me, the whole point of a gun this small is concealed carry and length of grip matters. I ran several magazines with various types of 9mm ammo. No problems so far. Only time will tell what the long term durability is. I think it will be good. I now trust this magazine for carry.

  131. Ryan G. (verified owner)

    I finally took my magguts magazine to the range. It ran flawlessly. I only wish Glock 43 mags came with a seven round capacity from their factory. I will carry magguts in my every day carry defensive pistol with total confidence in its reliability. Now I need to pick one up for my Ruger LCP2 also.

  132. Tom H. (verified owner)

    added an extra round to my factory magazines

  133. Clifford P. (verified owner)

    Works perfectly in my Glock 43 as I’ve come to expect from Magguts.

  134. Ryan G. (verified owner)

    Worked perfectly. Now I need a couple more for another pistol.

  135. Jason C. (verified owner)

    Bought 2 sets of internals for my Glock 43. They shipped fast and went in easy. Work perfectly and no hangups after approximately 250 rounds.

  136. Cullen T. (verified owner)

    Excellent product and company. Purchased a couple about 3 years ago for my wife’s Glock 42 and runs flawlessly. When I purchased my Glock 43 I knew I’d be making another purchase.

    This is my third one for the Glock 43. Picked up a third mag about a month ago, and after running 200 flawless rounds through my two original mags with magguts +1, I decided I should probably get one for the 3rd mag as well. Excellent quality and design!! Thanks so much!

    I attempted to contact you; wiTh no response from you. I wanted to send them back because I found it impossible to compress the spring enough and when I finally got it in I could only load 4 bullets. I took it out again and the spring was all bent up. I only attempted to use one of two I bought.
    Please help me resolve this problem.

    Well, I actually ordered these by accident because I really wanted the +2s. The guys at Corso made the return process really easy. While I prefer the +2, I’ve also bought a bunch of +1s before the former was released and loved them. Even combined them with a Taran +1 baseplate and could get it to work most of the time with 8 rounds (+1 in the pipe). Thanks Corso Inc.!

    I reached out to the Magguts Team, after having a USPS delay occur. They had shipped the product quickly, but it did not arrive by USPS Delivery Date and tracking was not updating. I emailed them on a Friday evening, and first thing Monday, which is fair, I got a response. They told me the tracking info had just updated Sunday night, which I had also noticed, but they promised to take care of it, if it did not show up.

    The package did arrive on Tuesday, and I’ve installed them into my magazines. Only thing left is to test fire, but the quality of these parts looks to be quite nice. Follow the instructions, and take a minute to ensure you did it correctly.

    Based on my interaction with them, and their response of offering to make sure it all went well, I’d recommend them on that alone.

    Thanks again guys!

    Possibly defective follower. Installed item following directions to the letter three different times. Also consulted installation vids on YouTube that were similar to directions on box. Follower kept getting stuck at the bottom. Metal follower has extremely sharp edges, which possibly gets it stuck on the sides. Each time it got stuck, took two rounds out and rest of ammo would fall out if held upside down. Decided to not use the product.

    Super product Bought 3
    Made clearance notch on the spring at the follower a touch larger.

    It’s just what I did.

    Combo with the +1 pearce grip
    Leaves the 43 a functional 8+1.

    Combo with the emp +2 should leave the 43 a functional 9+1.
    But that’s still yet to be seen😎

    Every 43 mag I own will have a zeespring.

    I put this into a hyve+2 extended mag to bring the total of rounds to 9+1 for my glock43 and it works just as good as any other magazine I have. *this config required taking a dremel to the bottom inside portion of the mag in order to prevent the plate from catching with a full mag but once this was done, no issues since.

    Seems to work as represented. I haven’t shot with it yet and it’s been installed for a week or two. I combined with a Pearce Grip +1 since someone else mentioned it in these reviews and got my standard size mag to hold 8 +1 without increasing the footprint at all. Very happy with this.

  244. Justin L. (verified owner)

    I really like the design of this +1 spring and follower. WHen you load that extra round, it is not jammed so tight in there that you have concerns that the slide might have issues picking up that first round, like with some mag extensions. I have not been able to try shooting with it yet, but I have manually cycled rounds through the action and didn’t run into any issues with extracting, feeding, or locking the slide back after the last round.

    I also purchased these, to run 8+1 with my Pearce +1 base plate extensions, as some reviews here have stated. The latest Pearce +1s, that say on the packaging that they are designed to work with Glock 43 -01 and -02 magazines, worked great with the Magguts+1 spring to allow for 8+1 rounds.

    Did range test it today, 220 rounds; 90 were two different JHP types (25 rounds of Hornady Critical Defense 115 Gr and the rest was PMC 9B 115 gr JHP) and the remainder was Blazer 115 gr FMJ. Zero hangups or issues, the gun reliably locked back on empty every time, and ran like a champ.

    I know these are not designed with this intent, but with my existing newer Pearce +1s, I added these and got 8+1. Ensure you follow Magguts’ install instructions closely, and you’ll be good to go, either way.

    I don’t foresee any issues, as I have a buddy who has literally thousands of rounds on his MG +1 springs with his 43, and he said their Z Spring holds up remarkably well over the years and round counts. These are now carry ready in my mind, even though 220 rounds doesn’t seem like much to some, it meets my requirements.
