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 is 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

    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.

  27. Brian (verified owner)

    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 support@magguts.com 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.

  64. Jeremy P. (verified owner)

    Easy to install into the magazine. Works great at the range.

    Why is it that myself and others experienced rattling in the mag

  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.

    Great addition to my Sig P365 XL, new spring can be challenging to install.

  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.

  146. ANDREW (verified owner)

    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!

    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 http://www.magguts.com. 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.

  230. Jonathan W. (verified owner)

    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.

    **updated**

    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**

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.

    Friggin awesome! work as advertised. ran a few hundred rounds so far, fed flawlessly and a slide-locked every time when emptied. the base pad also enhances the grip still keeping the gun sleek but adding more meat just where u need it… also, the added base pad meat makes seating the mag easier on reloads. 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.

    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.

    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!

    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!

  386. Sam (verified owner)

    I already had one of these for my p365 but I swapped the grip module to turn it into a x model and bought this kit to convert the mag to the flush fit 12 round instead of the extended grip 12 round for the regular p365. The first one I did went together smooth and had no issues but this one was a real mother to get working right. No idea why but the spring kept wanting to fold up instead of compress so I’d only get 6 rounds in the mag before it bound up. It would also catch one of the folds of the spring on the mag release cut out sometimes. I took it apart and put it back together a bunch of times and after some swearing and a little blood, it finally worked right. The other kit I had already converted easily to a flush fit mag for the longer grip module and like I said was easy to install when I first bought it so I have no idea why this one was so difficult. 4 stars for the frustration but still being a fantastic product once installed correctly. I’d still fully recommend these kits.

    Quick shipping. Love having the xtra 2 rounds in the mag. So far, seems to be a great product!

    Suggest install instructions include fitting/sliding the floor plate on & off a couple of times WITHOUT the spring in place. This ensures the plastic floor plate and metal mag floor plate track fit to one another before the spring install. Spring tension is STRONG, “aggravating” the ease of sliding the floor plate on. Just sayin’!

    I was very excited to learn of your product, but after trying for over an hour to install the first one purchased so that it would operate properly, I have to say that I am extremely disappointed. I even took it to my range to let some of the instructors try to get it installed correctly. The flat spring was bending easily in a way where it wasn’t working properly or you couldn’t get the end plate even installed. I typically shoot 300-400 rounds a week and I was excited for one of my EDC guns to get 2 extra rounds. I will be returning one of the two units that was untouched.

    I did initially have a lot of trouble getting the new followers spring in, it seemed that there was enough front to back play that something weird was happening, eventually I figured out that one of the sections was opening up too far and allowing the spring to bend around itself inside the magazine. I eventually was able to very carefully get it too line up properly and left it fully loaded for a few days which seemed to have gotten everything back into alignment, just wanted to let you know

    Great CS, quick answers to my questions, fast shipping. This is easily the first and best upgrade you should be getting for any CCW, especially for the P365; outside of perhaps a holster. The price point makes the upgrade a no brainer. The mag extension provides just the right extra bit of grip for the pinky, the spring allows for much easier reloading and the magazines themselves seat into the mag well much easier also. And then you get an extra 2 rounds capacity. No brainer upgrade, great concept. Can’t believe for the extra ~3/16″ of length to the magazine that these are not coming from SIG directly. Thanks guys!

    I installed as per the directions. The riser was catching on the front of mag wall on bullet #1 because the spring didnt keep pressure to the rear on the riser. The spring deformed inside the mag and promptly went in the trash.

    • admincorso (store manager)

      The spring in the magazine deforms because the spring was turned inside of the magazine tube during assembly and subsequently loaded. This cannot happen upon proper installation.

    The Mag Guts kit works as it was designed to work with no issues. The cost is where the problem arises.

    So I received my MagGuts and installed per instructions. I don’t know if this was a defective item or what, when I loaded the magazine the rounds loosely moved around in the magazine after 4 or 5 that I inserted.

    Not to mention it looked as if the packaged had already been opened.

    A complete waist of money and I was really hoping this would work. It did not to my extreme disappointment.

  499. james (verified owner)

    It was very difficult to load, following the installation, which was far more difficult than I expected. A good set of fine tools would have been helpful. The spring base kept slipping out, as I attempted to place the baseplate. Seems like a ton of money, aggravation and time for 2 more rounds. On the other hand, there is no appreciable increase in the length of the grip, maintaining the ability to conceal I desire. In that regard, the kit really delivers.

    The product works well as described. The feeder sits higher than a stock magazine which concerned me initially as I thought I had installed the spring incorrectly. Apparently, that is just the way it is. Pictures & instructions do not mention this so keep it in mind.

    Seamless. Effortless. I don’t know why anyone wouldn’t +2 rounds to existing mag. The baseplate that comes with spring looks better than factory baseplate. It’s a no brainer. Just do it.

  511. Kyal M. (verified owner)

    After 350-400 rounds, the base plate fractured the internal rails that grab the magazine body and the spring, follower, and base flew out of the mag while shooting. I am not impressed with the quality of this product right now. I like the idea but the execution is less than acceptable.

    As a senior, assembling the bottom base (plate) was difficult. I eventually put the mag in a vise so I could use both hands to install the base. Suggestion: If the back edge of the bottom metal plate was “formed up”, it wouldn’t slide to the rear of the mag when the base was being installed.

      Springs are usually bent when something goes wrong during assembly. The follower is unique (patent pending) and different from the Sig factory follower. It works great.

    Apon owning getting my Sig Sauer P365XL, I also purchased a Sig 15 round magazine. While the size of the magazine doesn’t add much to the size of the pistol, and also offers a nice bit of room for my offhand to grip, it prints a bit more while being a bit uncomfortable to toat around. This doesn’t bother me much, but when you’re a skinny guy like me any bit of print is an un-nerving feeling, so I order your product! I figured having 1 round less than 15+1 wouldn’t be bad. So far I love it, it’s great for carrying, offers a tad more room for my offhand to purchase, and it’s a tad easier to load. Reviews online are also really positive too, so far I’m with them. One question I have, is do you plan to make a product for the 15 rounder? It could be a great thing to have for the range, or bigger dudes who do carry the 15 round.

    Overall great addition to the standard XL magazines. Now my everyday carry magazines carry as much as the Sig factory 15 round extended magazines. I haven’t seen too much about poor reliability on these. I personally own two and have only cycled about 50 rounds through each under live fire. The only negative I could put forward is the price, which is almost as much as those factory Sig 15 rounders, so I guess it makes sense. Still, I would say these are a worthwhile purchase for anyone wishing to add capacity to your stock Sig p365X or XL pistol. I will probably buy the MagGuts for the 15 round magazines when they make them.

    I wish it would work with aftermarket baseplates but I understand why they don’t. I’d really be interested in a variant for the 15rd mags or even full size mags for the P320…

    Great company and product! Fast shipping and great communication! A++

    These are great. ran flawlessly and enjoy the +2 rounds with no increase in mag length. Just as advertised and have already recommended to friends.

  645. Timothy B. (verified owner)

    So far they seem to run great. It almost seems like a magic trick getting 14 rounds in a magazine that small.

    This is my second time I used Magguts to increase the capacity of my magazines. This one is amazing. It adds 2 rounds to the factory 12 round magazine……and barely adds any length to the magazine (I believe it is 3/32nds of an inch). I bought 2 so that both of my 12 round magazines could be increased. They run flawlessly. No issues at all! I highly recommend!

    I was looking for a little bit more room on my pinky and the extra two rounds you can’t go wrong with that. The other pinky extensions that I’ve seen were too big for a concealed weapon this maggut kit is perfect

  662. Bruce D. (verified owner)

    The MagGuts makes the OEM Sig P365x 12 round magazines much easier to load and I get 14 rounds in the magazine, no problem! I put at least 56 rounds through the adapted magazine with No issues. Easy load and easy feed, no failures.

  664. James (verified owner)

    Fast shipping – good quality product – basically carrying the same size magazine with two extra rounds. Just priced a bit high

  666. Joshua (verified owner)

    Works great! Put 300+ rounds in a day through one mag with this kit installed and had no malfunctions. Not difficult to install and I will probably purchase more. I would recommend this kit

    Purchased for Sig P365 XL. Ordered based on reviews and a lot of research. I ran into Issues with slide locking back with 1 round left in the magazine, happened every 4th or 5th magazine. Last round does not always move up high enough, happens starting with a full or partially full mag. Removed spring, cleaned/lubed and reinstalled spring. Re-tested with the same results. At this point I’m unable to recommend/trust Magguts for defense. Prior to testing this one I ordered 4 additional Magguts springs for other pistols, hopefully they do not have this issue and I just received a defect for the P365. I still have 3 stars based on the high probability this mag is defective.

  668. Larry T. (verified owner)

    Operates flawlessly. Now my P365XL is a 14+1 with standard mag.

  669. Joshua Holdridge (verified owner)

    Higley recommend who wouldn’t want an extra 2 rounds in there mag!!

  670. Leslie (verified owner)

    They can be tricky to install! After the guts are in the mag, slide the base plate almost all the way, the tail end of the spring will stick out. Push it in with a small flat screwdriver. Other than that, they are great for the Sig P365XL. I ordered 2 and highly recommend!

  671. Tyler (verified owner)

  678. Damian B. (verified owner)

    It olny adds about a 16th of an inch to the length of the magazine and its a bit tricky to get it installed the 1st time but by far the best option there is to add +2 rounds to the 365xl. Feeds 100% so far and the flat spring feels smooth and not difficult to load. For concealment this is the best option put there as of April 2022.
    Will absolutely be getting one for every mag I have.

  679. Mason M. (verified owner)

    Excellent product. The fact my small pistol rivals medium Glocks in capacity is exactly what I was looking for.

  680. Gary Moore (verified owner)

    Excellent product!! Will be getting more of them.

  681. Randy P. (verified owner)

    Bought 2 kits, the second mag I installed the +2 extension in, would lock the slide open with 1 round still left in the mag. Pulled the kit out and installed in another mag, and that mag worked fine. I honestly believe the issue was a tolerance stacking issue between the mag and the +2 kit. No harm, no foul but it was an issue to keep in mind especially if you are carrying these for ccw.

    Works and looks great on my 365XL with a wilson combat grip module. Shipped fast and was pretty easy to install. Way better to conceal my new 14 round capable mags than the 15 round oem mags for less money .

    I do EDC with my P365 with XL grip. My biggest gripe was capacity. This product fixed that issue by increasing the low profile 12 round magazine to a 14+1. The installation was super easy and had the simplest instructions ever. Even loading the magazines is easier now with the new magguts magazine parts.

  698. Joseph (verified owner)

    This is an awesome product. Easy to install. Adds the slightest bit of length which is perfect for your pinky. Adding this to your pistol I believe makes it the smallest with the most capacity. Will definitely buy from them again. Hoping they do something for the 15 rounders.

  699. Andrew D. (verified owner)

    I love the added capacity with only the addition of a couple millimeters. I also like the rounded-off edges of the base plate. My only knock on this kit is that it rattles inside the mag when I have all 14 rounds loaded.

  700. Jeffery Yaskus (verified owner)

    Love it, works great! I’m really hopeful that they will have the 15rd +2rd available before washington state deadline

  701. Erik M. (verified owner)

    So far so good. Magguts installed correctly and hold +2 as advertised. No range trips yet, so I cannot review the functional.

  702. Anonymous (verified owner)

    Bought these for 12 rd mags for Sig P365 X. Shipping was quick. Fits and works as advertised. Makes it easier to load all rounds and expands capacity to 14. With one in chamber, that’s equal to some full size pistols. I really like the slight flare on the spring retainer/cap. Magazine insertion is easier compared to the flush Sig Sauer cap, providing positive mag seating and retention. The red follower is great for easy magazine identification when unloaded to know which are 14 rd compared to 12rd mags. I’ve fired about 400 rds through P365 using two converted mags without failure. They are loaded for EDC and swapped every other month to let the mag spring rest. So far, a great product.

  703. Anonymous (verified owner)

    Really great product. Was a little skeptical at first, but very pleased indeed. Ran 200 rounds, mix of factory FMJ and HP as well as reloads (FMJ, powder coat and HP). Flawless function. In addition, it’s actually easier to load 14 rounds into magazines with this upgrade than loading 12 into the factory mag.
    Great job!

  707. Danny Warren (verified owner)

    I love the MagGuts +2 P365. The only issue I have is the follower sticks up considerably further than the stock and there is a gap that is unsightly. That may be necessary but I want to give my honest opinion. With that said, it functions flawlessly so far and as stated, I love it !

  708. Joseph C. (verified owner)

    Takes a little time making sure the follower & spring are correctly lined up. Putting on the baseplate Takes some patience due to the rear portion of the spring keeps popping out of the magazine body. Overall pleased with the end result. Can load 14 rounds easily without the use of a magazine loader.

  709. Christian (verified owner)

    Very cool after market part. Easy to install and works well. I was hesitant to use it for my EDC and hesitant to put a review until I tried it. I took it to the range and primarily used the magazine that I put this spring in and put a couple hundred rounds through it with absolutely no problems. Overall great product!

    Price is not bad considering what a new mag with two extra rounds would cost.

    This is a fantastic kit for my P365X. I’m new to doing modifications myself so I made sure to watch a few videos to make sure I had it right. It took under a minute to make the changes and it feels perfect. I bought other pinky extensions and they just don’t have the right feel. This kit does and adds the extra rounds. It’s perfect. I will be buying more kits.

  724. Bruce (verified owner)

    I have purchased 2 MagGuts kits for my Sig P365x. I have put about 70 rounds through each without any issues. They feed well so far and are extremely easy to load. The extra 2 rounds for $34 and barely any extra length is a preferable option to the OEM 15 round magazine that adds considerable extra length to the grip.

Magguts shipped me another one out and it was delivered in 3 days. I will definitely buy from them again in the future. If I can offer any advice to anyone looking to buy it’s worth the extra money to avoid being shipped through the mail.

    Ordering and delivery were no problem, but unfortunately the product is not very reliable. Therefore, I will not be able to use it as CCW, unfortunately I really had high hopes. After the 430 bullets I fired, most of the brass ammunition worked (I think all the brass ammunition worked), but the steel casings, even the brass-coated ammunition, were causing problems. I’m really sorry because I intended to buy two more.
    I hope this will help you in the future.

    It fit perfectly in my P365X and worked flawlessly through the 100 rds. It is easier to load the 14rds with the MagGuts than it was with the 12rds original spring. The only challenge was actually get the base plate installed without the spring sliding. LOL regardless, I wish they had more variations because I’d invest that purchase. Thanks folks!

    Awesome! The P365XL is already a superb gun, but +2 capacity makes it mind blowing! This kit allows near G19 capacity in a gun that’s barely bigger than a G43. The performance is perfectly reliable, and it only adds about 1/4 inch to the grip, so there is no reduction in concealability. HOME RUN!!!

  744. Jorge (verified owner)

    I used magguts on my regular 365. Even in the 12 rounder for standar 365. But in the mags of my XL gave me fail to feed like 4 times in 200 rounds. I took it for another session and again. Same problem. I lost confidence. I’m no using it.

  745. Alec (verified owner)

    Will change to five stars if next time I go out next and swap the spring out.

    My sig 365xl has never jammed after 500 rounds, granted thats only 500 rounds, and jammed at least two bullets per mag every time for about 200 rounds. I do have the dpm spring upgrade with the longest spring and large spacer. I’m gonna play around with the slide tension and the stock slide and see if I can’t find some harmony.

    If it works with only the stock spring will give four stars.

  746. Adam (verified owner)

    Took some effort, but I think it’s all installed correctly now. I won’t use as EDC till I’ve been down the range with it for a while.

  747. Trevor G. (verified owner)

    Badass. Super easy to install. Makes factory 12s the PERFECT length. They were just a little short for me to get a full comfortable grip. The extra 17% firepower per mag is pretty sweet too.
