Sig Sauer P365 X & XL +2 for 12 Round Magazine

(372 customer reviews)


This conversion reliably turns your Sig P365 X or XL 12 round magazine into a 14 round magazine with almost no length increase.  The spring, follower, and base are replaced with MagGuts™ components while the magazine housing and magazine sleeve are reused.  We pushed innovation through our “out of the box” approach to R&D and came up with a novel system that turns an already impressive capacity dense firearm into a weapon with a density of firepower that almost seems impossible.  With this conversion you will get:

  • Reliable feed and slide lock
  • +2 capacity increase with almost no sacrifice in length and no impact on concealment
  • Easy to load
  • Very slight pinky extension for perfect grip
  • OEM – like fit and feel
  • Highest quality spring and component materials used.
  • Cutting edge magazine technology [patent(s) pending]

Compatible with X and XL models and grip modules only.

    Love it. Item installed easy took it to the range, shot great and locked pack. Plus I like the little bit of pinky extension. Looking forward to the plus 2 for the 15 rounder.

    Very satisfied. Please notify me when the Spring kit for the P365X15 round magazine comes out. Thanks in advance MS

  12. David Lowrance (verified owner)

    I love the +2 capacity, and the base plate is very good, I would use the base plate for the tiny bit of extra pinky support it gives me even without the +2 benefit. Now I need a +2 or +3 for my 15 round magazine that is now useless since I have 14 rounds in a much smaller magazine. Start working on it! Thanks.

    I have used MagGuts products in my P365 with great success. Added capacity, easier to load, reliable. No brainer to pick up these for my P365 XL when they became available. Great product. Great American manufacturer.

    Easy to install, easier to load & 14 + 1 capacity w/ the 12rnd factory mags. The extra mm or so of lip on the mag base is also just right for a pinky rest. Home run upgrade for your EDC.

  19. Barry D. (verified owner)

    I bought one to give it a try and after a couple of mags of shooting with it I immediately ordered another one. Once installed it is no longer than the OEM 12 round mag but gives you 14 rounds. Worth it.

    Great Product.
    Easy to install. The slightly thicker base plate makes the grip very comfortable.

  28. James W. (verified owner)

    I purchased 5 of the spring,follower and floor plate kits. Installation was straight forward,floor plate should be installed a few times before installing spring (this helps to remove any little bits of floorplate material that should not be there. Now while holding the spring , slide the floorplate on till the little brass button pops into place.
    The price is a bit high but hopefully that will change.

  29. Kertis P. (verified owner)

    Greatest thing since sliced bread! I’ve been using/installing MagGuts products since I first modified a pair of S&W Shield magazines with the MagGuts +1 kits. When I started using a Sig P365, I thought the Sig magazines could use a MagGuts upgrade. This kit for the 12 round magazine, turning it into a 14 round magazine is perfect! These actually allow me to carry my Sig with 15 rounds on board (14 + 1 in chamber = 15 rounds). If you own a Sig P365 or 365XL, you owe it to yourself to install the MagGuts upgrade.

  30. joseph j. (verified owner)

    Great product. Only had a few rounds through it. I’d prefer to have many more before I can sign off on reliability. Brilliant product.

  31. Ivonelly (verified owner)

    So far so good. Everything fit perfectly and very easy to install. I haven’t tested it yet but looks very promising.

  32. Dean Everette (verified owner)

    I purchased 2 kits and they were easy to install. I took them to the range and ran about 100 rounds of ammo through each. I used 100 rounds of 115gr steel cased, 50 rounds of 115gr brass and 50 rounds of 124gr brass. I had one failure to feed half way through the first magazine (with the 124gr brass ammo). After that I had no more issues. The Magguts kits make it easier to load and seat the magazine with the slide closed. The tiny bit of pinky extension helps with my grip. My one complaint is that the magazine rattles after loading the 14th round (no rattle with the first 13). That could bring too much attention to a CCW. I’m going to put another 100 rounds through each mag before I trust them with my life. So far they seem like a good product.

  33. Alison Rhyne (verified owner)

    I used the + 2 today at the range. Functioned perfectly. Now I am going to be two 10 round +2 and an additional 12 round. I am very pleased.

  34. David (verified owner)

    Ran perfect 130 rounds including 30 JHP. Easy to install.

  35. Eric (verified owner)

    I am very pleased with the increases capacity. It did extend the grip profile very little not an issue just wanted to be transparent. I want to buy more if them, but the cost is a bit much for me. However, the technology is amazing to be able to easily fit 2 more rounds with out failure after est. 200 rounds and more to come.

  36. Carl (verified owner)

  37. Esteban Flores (verified owner)

    Put about 200 rounds so far and no issue.

  38. Thomas Gardner (verified owner)

    I have been using Magguts kits for several years. Two Smith Shields, a Sig P238, these two and my most recent, the 12 rounders for my Sig P365. I have had nothing but success with these kits and rely on them 100%. Several hundred rounds through each pistol with zero malfunctions. I am still amazed that you can get 2 extra rounds with very little grip length. When I pick up more mags for my Sig P365’s we will do this again.

  39. Spencer D. (verified owner)

    Works as advertised. Solid construction, feeds reliably.

  40. Anonymous (verified owner)

    Magguts spring and follower is higher quality than the OEM. A lot easier to load specially at the last 2 rounds. Very happy with purchase.

  41. Sean L. (verified owner)

    Did not work. Installed and reinstalled several times and all that ended up happening was a stuck spring in the magazine body and having to pour the rounds out. I finally gave up after the tenth try and removed the kit and reinstalled the original spring follower and baseplate and resigned the Magguts kit to the junk drawer where it belongs. I would not recommend trusting your life to this spring kit. Also I doubt anyone ever gets to read this review.

    • admincorso (store manager)

      The conversions definitely work. And of course we did not sensor your review! I’m not sure what happened during assembly, but we will contact you via support and help you get this resolved.

  42. Roy S. (verified owner)

    Does not have a grip sleeve or allow you to use the SIG sleeve

    • admincorso (store manager)

      There is no grip sleeve used on the 12 round XL or X magazine. Maybe you ordered the wrong item. Do you have the standard P365 (not X or XL)? If so you ordered the wrong item. If you contact we can help get this resolved.

  43. Joe (verified owner)

    Easy to convert your stock mags. Works great no feeding issues. Now 14rds from a Sig P365xl that’s legit!

  44. William M. (verified owner)

    Easy installation, discreet extra capacity with no downside.

  45. Abran V. (verified owner)

    I recently install a MagGuts spring on my 365xl and it fit beautifully. The only reason I gave four stars instead of five stars, is because I haven’t had a chance to run it at the range. If all goes well at the range, I’ll be grabbing a couple more for my other mags. Also, as a bonus, you can load all 14 rounds easily into the 365xl mag. Sig 365xl stock mags make that 12th round real difficult to get in there. It’s almost hard to believe that it’s the same mag.

  46. William M. (verified owner)

    It works as described, what more can you ask of a product. I actually put 100 rounds through the magazine down range without any problems today.

  47. Jonathan K. (verified owner)

    Does exactly what it’s supposed to! I get an easy +2 in my P365X. Only comment is I wish it was compatible with aftermarket basepads and not just the magguts one that comes with the spring/follower kit. This would have made it a godsend! Please consider future compatibility, or releasing a pinky extension for the XL models akin to other brands!

  48. Jeffrey Mosley (verified owner)

    This works as advertised , took only a few minutes and just like that went from 12 to 14 rnd mag . Will order again , highly recommend.

    I don’t know why this company isn’t more well known.

    I got the plus 2 for my factory 12 round 365xl mags making them 14 round mags

    The over all length is about 1/16 of an inch longer which makes the perfect size grip for me.

    I wish they sold entire magazines.

    I will buy a factory 15 round magazine when mag guts makes a plus 2 for them.

  66. Sean (verified owner)

    Shipping was fast! Installation was quick and it does what it advertises. 14 rounds in my 365XL fed better and loaded better than the stock spring/follower. I’ll buy more for the rest of my magazines!

  67. George (verified owner)

    The Sig365 with an XL frame and magguts +2 makes it the smallest, thinnest, lightest, 14+1 gun on the market.

  68. Joel (verified owner)

    I originally started using MagGuts with my Gen 1 Shield and never had any issues. This new kit for the P365XL works perfectly and it actually fixed a several issues I had with the factory mags. The new baseplate has a slight pinky extension which gives a full grip and the mags are easier to seat since they now protrude just a bit outside the magwell…no more pinched fingers! Also, the factory spring and follower had a tendency to “nose dive” rounds. The MagGuts spring seems to provide stronger feeding while also making it easier to load rounds than the factory one. I don’t know how they managed that, but my thumbs are thankful. Oh yeah, I almost forgot, you get 2 extra rounds…total win!

  69. Alison Rhyne (verified owner)

    These made my 12 round magazine’s into 14 rounders. Functioned perfectly at the range

    Thank you Magguts!!

  89. Chris Lamantia (verified owner)

    The ammo rattles when you load the 14th round in the mag but not when you only load 13. Cant stand the rattle

  90. Craig H. (verified owner)

    I don’t usually bother writing reviews… But this +2 kit for the P365XL is just excellent. It is placed squarely at the center of the four way intersection of function, form, ingenuity and durability.

    I’d use this kit for the base plate alone – the pinky shelf along with the rounded heal and side contour make the grip more comfortable in the hand and for carry.

    The mags are now easier to load, especially the last few rounds which were really tough on the factory set up.

    The only downside may be that installation is a bit tricky. One reviewer recommended prefitting the base plate without the spring first and that made it quite a bit easier for sure.

    Some complained about the price – I couldn’t disagree more. I found the kits to be thoughtfully designed and well made. Happy to support American manufacturing business. I bought eight kits to upgrade the entire family fleet.

    Looking forward to the +2 (or +3?) Kit for the 15 round factory mags that now seem pretty clunky next to the MagGuts upgraded 14ers.

  95. Samuel M. (verified owner)

    My initial kit had a defective spring. I contacted MagGuts and they immediately sent me a replacement spring. I installed the kit with the replacement spring and my 12 round magazine now accommodates 14 rounds.

    Excellent customer service, I plan to purchase several other kits from them. I highly recommend this company and it’s products.

  100. Anonymous (verified owner)

    I bought several of these for my P365X. They worked great. As per what others have suggested, install the base first, without the spring/follower so that any small imperfections from the manufacturing process are removed. It makes installing the base with the spring/follower much easier. Then just remove the base, install the spring/follower, then slide the base back on. Watch out for the edges of the spring. They are rather sharp. Be sure to fully load the magazine and then manually remove the cartridges before trying it in your pistol. The spring/follower needs to be fully “cycled” once so it functions properly. The only suggestion I can think of on how to improve upon this product would be for the spring to be deburred (tumble deburred??) before it was formed and plated. Off of that minor detail, it’s perfect!

    It not only increases capacity, it greatly reduced the effort needed to fully load the mag. After several mag dumps it operates flawlessly also. My P365X was failing to go completely into battery about twice per mag with the factory mags and this cured that. You guys could teach Sig a thing or two.

  105. Wilson (verified owner)

    So far so good ran about 200 rounds through it, dropping the mag on concrete several times. Loading/unloading is easily performed with your hand…good tension

  106. Robert (verified owner)

    Ordered two + 2 kits for my P365XL. Have a couple hundred rounds thru both mags and have had no issues with either mag. Slide locks open when empty and no failures to feed. Kit was easy to install and it’s nice having 29 rounds at my disposal in such a small package.

  107. Kevin P Tittle (verified owner)

    I am appreciative of the design and the ability to have extra capacity. However, the magazines (which are SIG, OEM, and USA made) were fully loaded or unloaded, there is a pronounced rattle when moving. (I believe it is the main spring slapping around in the body.) When the magazines are in my kydex mag carrier the sound is magnified and reminiscent of dominoes in a tin can. This is not good, considering they are my EDC mags. I like the concept of extra capacity but I believe some review and tweaking of the design need to occur. Idk if anyone else has experienced this issue… but I have contacted customer service, and at this point, their response has been ‘Thank you for the feedback, We’ll look into it.’ I truly hope they will and resolve it. I WANT to believe in this product!

  108. Seth (verified owner)

    Might’ve just been an isolated issue, but the plastic baseplate was too narrow to fit over bottom P365XL 12rd mag. Took me roughly 25-30 attempts to work a groove into plastic enough to slide baseplate into proper placement on mag (significant force was needed to get plate into position). During these 25 attempts the Magguts spring became misaligned & would “fold into itself” inside me mag, causing bullets to pour out of mag. I removed baseplate, reinstalled the spring another 5 times to get spring back into alignment, but same issue persisted every attempt. I emailed their support & they quickly responded, stating that “If it is turned during installation you will have the problem you describe.  Once the spring bends out of shape it will be very difficult to get it right.” Either way, I sent the item back & they are taking care of return. The support team were courteous Folks & I’m bummed this product didn’t work for me.

    They were little harder to put together than shown in the video.

  110. Justin J. (verified owner)

    Excellent quality. I bought three sets and they are completely identical working flawlessly and there is absolutely no rattle like other magazines can do with aftermarket extensions. Very happy with the added capacity. Definitely recommend.

  111. James Piccone (verified owner)

    Preforms flawlessly and locks in better. The stock 15 round mags are not worth it if you get have 12 round mag +2 Magguts. Literally one round less and almost exactly the same size as stock 12 mag’s. Also now with Magguts it doesn’t feel like the magazine is going to burst at the seams when fully loaded. In my opinion it would be even better if they made the base plate as small as stock.

  112. Marquette Moseley (verified owner)

    I love the product

  113. NEAL WOOD (verified owner)

    Works great on my twelve round 365XL mags. Added bonus, the 14th round is easier to hand load than the 12 round in the stock magazine.

  114. Jason (verified owner)

    Bought 3 for my P365XL. So far they have worked without issue. I’ve run each magazine 5 times, the last two times with a loaded chamber and full magazine. Hoping they’ll continue to work great after the springs have been compressed for extended periods of time.

  115. John W. (verified owner)

  116. Jordan (verified owner)

    This fits beautifully in the 12rd mag and gives you the 14rd capacity without that much added length. I have yet to see if it feeds properly and the longevity of the spring but overall I’m happy with it. If only the mag wasn’t 45 dollars and this kit another 35 dollars making one mag worth 80 dollars I would buy for all my mags.

  117. chris (verified owner)

    Quite a bit more difficult to install than the other p365 variants, but still an amazing product. 14 plus one in a micro compact?! My Glock 19 is now a paper weight. 100% function rating on all 4 of my mag guys P365 mags. Can’t recommend them enough.

    +2 in a 12 round mag is pretty huge, especially for a carry gun. For $37 I feel like the follower side spring should have been riveted or something other than “plastic peg through a hole then melted over”…. it reminds me of a Chinese kids toy but maybe they found this was the best way after testing and such. Haven’t actually field tested the mags for proper function but it feeds by hand and locks open so I guess it will work.

  142. James R. (verified owner)

    The metal spring part is tight (and sharp too!) and tough to hold down while you get the bottom plate slide in! Hopefully the next one will go easier!

  143. Calvin Carter (verified owner)

    The follower appears to be inferior to that of the manufacturer’s. To the point that it seems like it tries to bind in the mag. When manually racking unspent Hornady
    Critical duty from my p365 xl, round 13 and 14 hang up most of the time. Naturally after it occurred the first time you try, you repeat many times to see if it continues. It does. There is end to end movement of the mag in the well when empty also. I’m then met with the attitude that there must be some other problem. After reassembling the original mag components, it operates flawlessly. And then have the audacity to put return freight on the buyer! I really wanted this to work. Who wouldn’t want two extra rounds?

    My Sig 365 XL is my first firearm and the Magguts magazine my first firearm modification. The Conversion was super simple and maybe took 5 minutes to complete. I’m looking forward to taking it to the range in the near future!

  145. GARY STEWART (verified owner)

    Installation of your product was easy and holds 14 rounds as advertised. Haven’t had a chance to take it to the range and test it out yet. That is coming soon.

    Purchasing MagGuts for the p356x is like having a baby. I found it painful to get the thing into the magazine. I cut myself, obtained a bandaid and kept going. The only thing that was different from having a baby is there was no doctor yelling “PUSH! PUSH!” But in the end, I succeeded. I loaded the 14 rounds easily and it functioned perfectly at the range. So I bought 2 more. I was able to get numbers 2 and 3 in more quickly (and without bleeding) and now I have 3 robust mags for a total of 42 rounds on my person. And I won’t even have to buy diapers. Happy camper.

    The MagGuts were easy to install, like the slight length added to base pad. Only ran a few mags and they fed great. Will run a couple hundred rounds through each prior to carrying, so far they are awesome. Allows carrying a P365X or XL with 14 rounds vs a 15 round M&P compact or Glock 19 size pistol.

    I just got two of the +2 MagGuts for my Sig 365XL. They installed fairly easily. Instructions were simple and clear. A little tricky keeping the spring compressed while sliding on the baseplate.

    I haven’t been to the range yet, but I manually operated the slide with 14 in the magazine and both mags ran perfectly from the first to last rounds.

    I’d love to see them available for my Smith and Wesson Shield Plus. Wouldn’t hesitate to buy again.

    Great customer service! I had an issue installing a spring which got pretty bent up. Emailed them and several days later got a response that they’d send out a new one! Definitely restored confidence in the purchase and company overall, so 10/10 for CS.

    So far I’ve had 1 or 2 FTF on the first 200rds with the mag. Long term use should give more definitive results. Too soon to review actual product thoroughly. Give it a try for yourself

  165. Kevin (verified owner)

    Good kit. Does what it claims but some care needs to be taken to make sure the spring goes in correctly. One of mine tweaked a little and prevented more than 8 rounds being loaded. Once I fixed this, remove and re-install, everything was fine. Only complaint is the price. I can buy a new 12 round mag for only a few dollars more. So it comes down to having two more rounds or 12 more for the price of a few seconds to reload. Granted, there are potential issues with that as well.

  166. Steven Bemben (verified owner)

    Price was reasonable but it would always be nice to be a few bucks cheaper or score a discount code. The way she go bubs.

    I am so glad I found you guys! I can surely say that MagGuts is one of the best extended mag insert out there! I love how it doesnt change the geometry of the gun but adds just enough to cover my pinky and gives firm grip while shooting. Highly recommended!

  168. Stephen (verified owner)

    So far, so good. Arrived quickly and assembled without much difficulty. The slight extension of the magazine length is a bonus. Have not yet had time to take it to the range – should do so next weekend. Looks like a winner!

    I haven’t gotten a chance to shoot it yet, but it’s a very easy install, loading the magazines to 14 with Magguts is actually easier than loading the standard 12 round in an OEM mag. Very solid construction, and look promising. Only complaint is a slight rattle when the mags are fully loaded but it doesn’t bother me and doesn’t seem to affect the mags at all.

    This magazine upgrade is perfect! It’s really easy to install, and does exactly what it says it’ll do. Upgrading from 12 to 14 rounds and having the extra pinky grip from the base makes this a must have upgrade for anyone who owns a p365xl!

  185. GREGORY (verified owner)

    Excellent product! If I would’ve known about this product ahead of time, then I wouldn’t have waisted my money on buying an oversized 15 round clip that sticks way down from my grip. This 2 round extension is perfect and it has just the right amount of space to put my pinky on. I can’t recommend this product enough. And to top it all off it is a very simple install that I was able to do myself in less than 5 minutes. Buy this product with confidence, you won’t regret it. And FYI, I’v had no failure to feeds or ejects. Stay strong out there my fellow patriots and God Bless.

    Unfortunately, it might be user error, but I didn’t feel safe using these with my magazines or trusting them with my life in a CCW manner. I read the conversion instructions and read them as I went, and also watched the instructional video at But the issue I was having was that the magazine bases with slide forward despite the brass button locking into place. This would happen while firing and while loading. Again, perhaps user error, but I’m just not sure if this product is for me. Thank you for the opportunity to share my experience.

    Little pain the butt to get the spring to compress all the way to slide the new baseplate. Other then that it is due able. The extra pinky extension makes the sig 365 xl fit the hand a whole lot better. Have yet to test the reliability of the new mag spring at the range. Will update review this coming weekend.

    I bought 2 magguts for a 365X and only one worked. I triple checked to ensure proper installation in both mags. One of them functioned perfectly through 8 fully loaded mag dumps and the other one wouldn’t load more than 7 rounds. I took it apart and the spring is all messed up now. Not sure what happened considering it was installed properly. Needless to say I was pretty bummed out. I’m going to reach out to customer service and see if I can send it back for an exchange. Hopefully it was just a fluke. **Customer service was great, they switched out the springs and the 2nd one seems to work fine now. I’ll probably pick up 2 more**

    I received my magazine conversion package for my Sig P365 XL in a timely fashion. I had issues installing the product which resulted in a failed conversion. I contacted customer service and they quickly responded by sending me another set of MagGuts conversion parts. The second time around was a successful install. Now all I have to do is test with some range time. Kudos to customer service for a quick and positive remedy to my issues. If all goes well at the range, I will be buying additional MagGuts for me and for Christmas gifts for family and friends.

    My only negative with these is, for me at least, they were the hardest to install. Between the powerful spring and the base plate, it was a chore. Have installed 3 of them, I think I have figured out how to do it better. The 10 rounds and the P365 12 round mags were much easier to do. That said, all 3 types of magazines worked like magic. With hundreds of rounds though them, I’ve had zero problems and would highly recommend this product.

With just 1 less round than a glock 19, this kit makes the p365xl a no-brainer replacement… can’t wait for the +kit for the p365xl 15-rounder

    I purchased 3 maguts for a P365XL 12 round magazine to increase to 14. 2 were very hard to install, but works great now. The third kept binding in the magazine and after an hour I quit and threw it away as it was deformed so badly. I installed the same way, but not sure why this one kept binding. I installed them on 3 new magazines from Sig so not sure why the third didn’t work. Otherwise I would have given 5 stars.

    Not sure why, but it took me approximately 25 attempts and 35 minutes to install this. Getting the spring flange to set properly in the Mag Guts base proved highly tedious. Eventually I utilized a screw driver to get the job done. Installing MagGuts into my 10 round P365 mag though was a breeze. I had an equally easy experience installing my plus one and plus two guts in my Shield mags. I’ve had guts in my Shield mags for more than four years. They’re 100% reliable. Love your product.

    Fast delivery, shipped same day. The baseplate gives a very nice subtle pinky extension that’s a perfect fit. +2 capacity is a no brainer why not have extra ammo in your carry gun. Very easy installation.

    Just installed MaGGuts into a Sig 365X Mag and works perfectly so now mag holds 14 plus 1 and grip is improved and more comfortable. And only about 3/32″ longer, pistol grip. Superb but, a little too expensive.

    Very pleased with the new spring sets. My hands aren’t as strong and nimble as they used to be so I placed the mag body into a vise with rubber lining and it was easy to install the new spring. 14 load easier than 12 with old spring. Snapping the old mag into the well was difficult. I also sensed the slide slowing down pulling up the first cartridge. No problem with new spring. I only ran 11 rounds due to the extra stress caused by 12. 14 now run easy but I will still only load 13 due to concern over spring stress. Still gives me 2 more than before. The bullets set at a higher angle making for easier chamber feeding and reliability. The1/8″ extra finger grip feels perfect. Even the the rear of the floor plate blends seamlessly with the rear of the grip. Better than original. I can find no negatives. These springs are an enhancement and reliability to the firearm. Originally ordered two springs and just ordered 2 more. The overall enhancement features of these springs are more important than having two more bullets. Thanks for a great product.

    Nicly packaged, excellent quality, far better than the stock Sig spring.
    Easy and intuitive installation.
    At least 3 new customes bacause of my posting a review on a Sig P365 fan page.

    Work without any issues in my P365 xl. They are about 1/4″ longer than a stock mag but not real noticable. I love having the two extra rounds for the same size.

  317. William Rollins (verified owner)

    Great product!! Would highly recommend!! 2 more rounds with no noticeable added length!! It actually feels better than the stock mag!

    The magguts kit 14+1 for p365x works great. I’ll be ordering another one.

  321. Brian A. (verified owner)

    Way easier to load than the factory mags. Was a breeze to change the springs. A genius idea! Also mag is easier to load/sest when slide is forward…..Now they just need to make a kit for the factory 15rd mag. Great product!

  322. Anthony M. (verified owner)

    Little trouble getting the base plate on . But the magazines works flawlessly put about 60 rounds through so far.

    Excellent product. It was easier to get the 14th round in the magazine after the kit was installed than loading the 12th in the stock mag.

    Very happy, order arrived super quickly – and the product is fantastic. I would highly recommend.

    Better then the og mag it’s super nice it would be awesome if they made a 15 round magazine plus 2 maggut

    Absolutely Fantastic. Holy smokes was this what I needed with my big hands. I’m blown away that this little added to the bottom of the mag would make that much of a difference

    Excellent products. It increases my capacity and tried it at the range. Simply awesome. The service was excellent. Good job. Will be getting one for my 10 round Mag.

  330. Don (verified owner)

    Tended to hang up when half loaded. At first could only get 13 rounds, not 14.

    I couldn’t get more than 7 rounds in them after assembly. I tried everything. Had to trash them

  334. David Anderson (verified owner)

    Amazing to have 2 extra rounds and still not be super bulky. Way to go on this product. A little pain to install but 100 percent worth it.

  335. Billy (verified owner)

    To think that you could fit two extra rounds in the 12 round mag with no more extension of the base plate is simply amazing to say the least.
    If you ever come up with a 15 rounder for the p365xl please let me know.

    This was different to install, but once installed it works great and only adds a fraction of and inch to the overall lenth of the magazine. Would buy again!

    After you get it installed correctly it works fine, spring gave me issues going in correctly but eventually got it to go in right and all functioned great. Well worth the money for a few extra rounds in the same footprint.

  342. Joshua Slater (verified owner)

    Magguts work exactly as advertised,but better!Easier to load up full 14 than factory 12.Customer service was contacted due to an ordering error on my part and also get 5 stars. I Am ordering more for sure.Get a Magguts window sticker on your order before you submit it,looks great on the jeep!

  343. Winston H. (verified owner)

    Perfect fit and finish right out out the box for Sig Sauer magazines. Less than 5 minutes to install both gutts!

    I have always been impressed with MagGuts products and own several. Adding two reliable rounds the the P365XL is awesome. Since installation, I have had absolutely no failures of any kind.

    Super reliable! It feels like jamming 14 rounds into this tiny magazine is some kind of magic trick.

  351. John D. (verified owner)

    As far as ordering and receiving the product, I have no complaints. However, I purchased the magguts for the p365xl. I went to the range today (11/21/21) and while shooting suppressed the base plate completely failed causing the bottom of the magazine to come apart violently. I will be returning these because they do not seem to be safe for suppressed shooting.

    The Magguts for the Sig P365XL is probably the best outright purchase you can make for your pistol in terms of value and performance. Having 14 freedom seeds in a 12 rd flush fit mag is truly amazing and takes the capacity of this weapon to a whole other level without compromising the concealability of the flush fit mag. Did I mention the conversion is easy and takes very little effort! My only wish is that Magguts would make a +2 conversion kit for the 15rd mags to take the capacity up to something that rivals a compact/full-size pistol. Truly a great product! You won’t regret it!

    It arrived within a week and works great. It actually gives the sig 365x a better feeling grip than the factory. I love it

    Great product! Just ordered second one. Customer service is wonderful.

    Was recommended by a co-worker and saw how it ran during the range without issues. I bought 3 of these for my p365x and installation was simple and has a clean look. The grip feel does not change and barely adds any length. Going to see how it holds up long term. Having a total of 14 rounds in this compact great!

  358. Chris B. (verified owner)

    I am happy with the product. It seems to work as advertised. However I have not been to the range. I have a feeling that there is the potential for the follower to bind up of it tilts as it’s really narrow. But Parts had to get smaller to add 2 rounds to capacity in the same size mag. I also have noticed the back
    Of the bottom plate is not matched to the grip it’s more squared off. And provides a bit of a sharp point in your side. Nothing a little sand paper can’t fix. But it would be nice if they were rounded instead of square.

  359. Jason L. (verified owner)

    Works well and fits an extra two rounds like a charm. The only annoyance is a bit of bullet rattle when walking but this happens with some wire spring mags too so what can you do? I wish the price was a little cheaper and they made them for other full-size guns like a PPQ/P99 compact (hint, hint) if those would gain some rounds since a full-size model is just easier to control but the compact is only 10 rounds. Hopefully, they’ll see where the line can be expanded. How about one for the 15 round P365 mag to bring it to 17-18 rounds too? Lastly, I love that the business is out of Wyoming which is one of the most American value-loving states left!

    Perfect upgrade for my sig P365X. Adds a slight but improved amount of grip as well as 2 more rounds.

    Seems to work as advertised. Test fired a few hundred rounds and the pistol ran without fail.

    A little pricey for what it is, but overall satisfied with increased capacity.
    Will test at the range for reliability soon.

    Easy to install. Works great. I ran 150 rounds through two magazines with absolutely no failures and the slide stop worked every time on an empty magazine.

  369. Micheal (verified owner)

    So far, these work as advertised. They are pretty solid and work perfectly in the mags of the P365X. Having a few more rounds is always helpful in a crisis!!

  370. craig hagen (verified owner)

    With the +2 makes for 15 in the gun and with a 15 round extended mag I’ve got 30 rounds in my edc. Can’t wait for the 15+2!

  371. Matt H. (verified owner)

    I don’t leave a lot of reviews but when somebody comes up with a great product I will. These are a 100% improvement over stock springs. Somehow they managed to fit more capacity with easier loading, all while keeping reliability. Awesome stuff! Looking forward to the 365xl large cap mag springs!!
