This conversion reliably turns your Sig P365 10 round magazine into a 12 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
  • 20% capacity increase with almost no sacrifice in length
  • Easy to load
  • OEM – like fit and feel
  • Highest quality spring and component materials used.

  1. Donald (verified owner) –

    1. Your finger ledge is shorter which for bigger hands is a negative.
    2. There is no texture like the SIG original. I will most likely take them to a local laser firm and se if they can add texture. Especially given 1. above.
    3. The lower back lower corners stick out past the frame and create a sharp point that bites into your hand. I filed mine off to match the frame. They now feel great.

  2. Stan (verified owner) –

    Fast shipping and a fantastic product. I am buying these for all of my carry mags.

    Product: Excellent, install instructions: could be improved. I just installed my MagGuts but haven’t been to the range yet to test. I needed to view a couple YouTube “how to install” and the testing results videos for help, since the P365 instructions weren’t posted on the MG website. While the directions on the box make install seem easy, the actual install never goes as smoothly. This is my 3rd purchase, 1st for P365 and 2 previously for my Kahr CW380.

  9. Anonymous (verified owner) –

    Works great and adds little bit in length to the mag enabling a better grip. Highly recommended.

  10. Ray K. (verified owner) –

    I installed these +2 kits in my 10 round SIG P365 magazines. The instructions were easy to understand and the installation went smoothly. The mags now hold 12 rounds easily with no problems loading the 12th round.

  11. John (verified owner) –

    Very reliable and slide lock every time. I highly recommend these. I use these for my EDC.

  17. Michael P. (verified owner) –

    have installed the unit but have not shot the gun yet. Installation was simple and easy. Have one installed on my Glock works flawlessly. Great product.

  19. Michael Martinez (verified owner) –

    Great product! Was waiting for something like this!

  20. Quang (verified owner) –

    Fantastic product. Ordered two. I ran a bunch of different ammo on this new +2 mag (Speer GDHP Short Barrel +P 124 Gr, Speer GDHP +P 124 Gr, Speer Lawman TMJ 124 Gr, Win Ranger T +P 124 Gr, Win Silvertip Defend JHP 147 Gr, Federal Tactical HST +P 124 Gr, Rem Golden Saber BJHP +P 124 Gr, Fiocchi FMJ 124 Gr, PMC Bronze FMJ 115 Gr). No a single hiccup. The only reason I didn’t give a 5 rating is this. The rear bottom corners are sharp and poking out. Not fun when you grip the gun. Not a major deal, however, since a little rounding out using a nail filer quickly solved this. Liked it so much, I just ordered 2 more.

  21. Anonymous (verified owner) –

    Always quality that works from Magguts!

  22. Jose Lopez (verified owner) –

    Works great like all your maguts

  23. Robert Bailey (verified owner) –

    Nice, seems to work as it should, will take to range!

  24. Robert G. (verified owner) –

    Simple to install and easy to load all 12 rounds and fire reliably, thanks.

  25. Kerry Coyle (verified owner) –

    Works like a charm plus it added about 3/16 inch to the overall length of the grip making it feel better in my hand.

  26. Richard (verified owner) –

    Great upgrade for my Sig P365, can’t comprehend the wizardry that lets you squeeze 2 more rounds into that tiny magazine. The springs and follower felt well made, the install was easy with good instructions and pictures provided. One small complaint was the bottom corners of the base plate protruded from the rear of the grip and were uncomfortably pointy. I do have 2XL hands that are on the “meaty” side, so problem might be unique to me, but it took less than a minute to round off the plastic corners slightly with some sandpaper. I even like the little brass button that locks the base plate in place, it adds a little accent to the modified mags.

  27. Kee (verified owner) –

    I have told many people about your product. I have really enjoyed your innovation.

  28. Scott P. (verified owner) –

    Great quality, functioning 100% so far. Used their internals for my S&W Shield for years; I have faith in this company.

  29. William G. (verified owner) –

  30. Kevin F. (verified owner) –

    Installed easily. Haven’t tried them out yet. Covid has range shut down

  31. Anonymous (verified owner) –

    Works better than original with an older P365. It fed a variety of defensive and range rounds without any problems.

  32. Fernando C. (verified owner) –

    Tested both Magazines. Fired over three hundred rounds with both mags. No problems so far!

  33. Dwayne H. (verified owner) –

    Like added rounds but would like extended grip too

  34. Anonymous (verified owner) –

  35. Camden M. (verified owner) –

    It was already a game changer when Sig came out with the P365 and a 10 round mag! Now my 10 rounder holds 12! Awesome! Thanks MagGuts! I’ll be ordering a few more!

  36. John S. (verified owner) –

    An excellent product in every way. My primary reason for upgrading to these parts was because they were reportedly easier to load than the factory magazines. That turned out to be true, and I went from being forced to download the mags to easily having an extra two rounds over what the originals were supposed to hold (and was almost impossible to load). Highly recommended.

  37. Ron (verified owner) –

    Fast turn around easy installation perfect little product great addition to 365

  38. Mike Mueller (verified owner) –

    Great

  39. William Key (verified owner) –

    2 more shots and no increase in length. A little heavier but to be expected with 2 more rounds.

  40. Jon Bowman (verified owner) –

    It isn’t a plus 2 its a plus 1 and it added no length to the grip. I wanted a slightly longer grip. Overall the description isn’t correct. Had I know this I would have purchased new mags from sig.

  41. E.J. C. (verified owner) –

    Ease of installing and preformed flawlessly! Happy customer! Highly recommend!

  42. Michael M. (verified owner) –

    Excellent product. Super easy to install

  43. Michael (verified owner) –

    Great mag conversion! Works like OEM but 2 more rounds.

  44. Geno B. (verified owner) –

    It was fairly easy to put in however the follower kept sticking and not moving freely. I have not used it at the range so I don’t have a complete review yet

    Love magguts I have this product for several different guns and they all work flawlessly. 1 or 2 extra rounds in the same size magazine its awesome. Buy it you won’t be disappointed.

  50. Gordon Weis (verified owner) –

    the best is adding on to my 4 mags 2 each making an extra 8, wow awsome thanks

  52. Anonymous (verified owner) –

  53. Michael Brown (verified owner) –

    Extreme easy to install, and works perfectly. Also, for the flush mount mag, made it more than a paper weight as the baseplate allowed room for my pinkie on the grip.

  54. Daniel Brown (verified owner) –

    Excellent product. Simple to install. Haven’t had any issues.

  55. Vincent L. (verified owner) –

    Installed in minutes works flawlessly.

  56. Robert (verified owner) –

    The kit worked perfectly. It took maybe a minute to make the change. I did find that the sharp end edge (back of mag) had to be filed down and rounded off for my likes – but no big deal, a jewelers file and some 3000 grit sand paper made quick work of the modification. Very please and I highly recommend the kit.

  57. John Benson (verified owner) –

  58. Oliver (verified owner) –

    Fit perfectly. Don’t know why they don’t come this way from the gun makers. 12+1 in a compact package makes the Sig 365 a great ccw.

  59. Scott G. (verified owner) –

    Overall quality is great! However, there are a couple things holding it down one star. The very sharp/pointy edges on the back corners of the base plate really dig into the palm of the hand. I used a small file to remove those edges and it feels great now. The only other thing is that the front of the base plate is VERY smooth. I used a very sharp pointed neck knife to add some additional texture and now it feels like the rest of the grip module. I still highly recommend these base plates.

  60. Chase (verified owner) –

    Easy installation and very reliable. I did not have any feed issues after installed. The size is about a quarter inch longer than the flush fit.

  61. Michael (verified owner) –

    Couldn’t be happier.

  62. Phillip LaFlamme (verified owner) –

    Shipping was very fast, the new guts went in easy and I loaded up 12 rounds with no problems. Love it!

    Pretty cool product and so far it works well

  65. Michael G. (verified owner) –

    Very easy install. Very little difference in length. Functioned perfectly through 3 reloads on first trip to the range. I expect it will continue for a very long time.

  71. Christian H. (verified owner) –

    Works as advertised adding 2 additional rounds. Few issues 1. Seemed to be lose and rounds/spring would shake issue seems to have corrected itself on this one (not 12rnd kit) overnight no shake if heard. 2. The pinky extension is not stippled like the one that comes from the factory (not a big deal but something to be aware of) 3. The back corners of the bottom of the mag can be a bit sharp just need to be filled down so they don’t dig into your hand. Otherwise great product so far still need to test at the range to see if it will be reliable.

  80. Matthew S. (verified owner) –

    I found it easier to get 12 rounds into the mag with the MagGuts kit installed than it was to get 10 rounds into the original mag. Shooting it 12+1 with 115 FMJ, 124 FMJ and 147 Federal HST I had no malfunctions in the first 150 rounds through the MagGuts equipped P365. Very good initial impression.

    Installation was quick and easy. Have shot a few hundred rounds through these without failure. Great Product

  86. Jatniel Rodriguez (verified owner) –

    Took out to the range rand about 200 rounds and functioned fine with all sorts of ammo plus P and reloads as well I will start carry with these. I think they are pricey for what they are priced at about 25$ I think would be more reasonable and would make me buy more but the fact that you can have plus 2 rounds in a frame so small I think is worth it and it’s impressive how they don’t any any real noticeable length to the magazine.

  87. Michael A. (verified owner) –

    Also works as described. Easy install

  88. Micah H. (verified owner) –

    Love the addition of 2 extra rounds! There’s a subtle rattle when the mag is in the firearm, but I’m hoping that’ll go away after some time.

  89. Joel (verified owner) –

    Easy install, works as advertised, +2 🙂

  90. George NEWHOUSE (verified owner) –

    Could only got one extra round in a 10 round mag.

  91. Christopher Sizelove (verified owner) –

    Fantastic quality. There’s a reason why they are highly reviewed. I have LCP, LCP II, P238, and P365 kits.

    Here are my two complaints. It doesn’t matter if your order is $240, you will still pay shipping. I think they could do a free ship policy for orders over $100. And then second, they haven’t had LCP II kits in for years. And I need 6. Been needing 6 for years. So I give 4 stars.

    But otherwise, I can’t say a bad thing about the products.

  92. James S. (verified owner) –

    So far these have been great! Simple installation, and they have functioned flawlessly what I’ve gotten to run em. Will be purchasing for any additional mags I get in the future.

  94. Richard Dillon (verified owner) –

  95. David A. (verified owner) –

    I’ve not shot the mags after installing the kit. But they strip rounds by hand better than stock. Plus they load a lot easier. The only negitive I can think of is the base has some sharp corners. But that is a easy fix with a nail file. I’m pretty satisfied with the kit.

  96. Anonymous (verified owner) –

    It feels weird when installing it. The original sig mags are not the same quality as walther, however, the magguts are freaking amazing!
    They work extremely well and hold 14 + 1 in my 365. 14. That’s insane!

    Magguts deserves respect and business.

  112. PAUL E. (verified owner) –

    Tried and tried, even contacting customer support, but could not get it to work. I used a new, never used, OEM Sig magazine. The last two or three when loading were next to impossible to get in the magazine, and about half the bullets were nose down. There may have been a defect with my particular product. Support staff was trying their best to help and the company willingly accepted my return. Easy folks to work with.

  113. Ed F. (verified owner) –

    Good product! This was the first chance I had to try these new mag springs/followers since purchase, and I was pleased. The magazines load smoothly and feed the same way. Springs are stiff to load with a thumb, but I figure that will change in time. Using a mag loader makes loading a piece of cake. I put 50 + rounds thru the gun this morning using 2 magazines and suffered NO FTF, stovepipes, FTE’s.
    I’m happy !! Nice work!

  114. Richard (verified owner) –

    Works great.

  115. Anonymous (verified owner) –

    Very well made, works as advertised, that extra 2 has still put my 365 in top spot for carry 👌

  116. John Carbone (verified owner) –

    Only reason I gave the sig a 1 is because the spring is not compatible with my extension grips. In other words the spring button on the bottom does not secure into my extension grips

    • admincorso (store manager) –

      The MagGuts base that comes with the conversion must be used. Other aftermarket grip extensions cannot be used in combination with the MagGuts parts.

  122. Jonathan W. (verified owner) –

    Disappointed. My main complaints are:

    1. Pinky ramp is smaller than the OEM extended 10 round mag. The factory extension was barely adequate for me.
    2. No stippling on at all on pinky extension. Combined with the smaller extension hand feel is greatly reduced.
    3. Sharp hot points on rear of extension that 99% of users complain about and modify (easily) at home. Shame on you Magguts.
    4. The follower is a muted red color, hunter orange would have been a nice touch. Follower is also not as nice as the OEM option as it has a significant hole when the mag is empty.
    5. Price. At nearly the cost of the brand new OEM mag, I expected better.

    I am a long time customer of Magguts on a few firearms.
    This could have been a homerun product like the +2 for the OEM P365 12 round mag. Instead of taking advantage and continuing Sig’s ergonomics Magguts struck out for me with poor design, and fitment. I wanted to like this product, but I will carry the OEM extended 10 round mag, with a +2 12 round spare mag (which is pricey still, but great).

    Seems like a great product, edges and back corners are a little sharp and could use some smoothing to be more comfortable. Also the plastic injection point is very obvious.
    Great fitment, holds 11 rounds very comfortably, the 12th is as tight as #10 in factory form.
    Shipment was quick; would recommend this product so far, testing is still needed to see if it functions as intended in the real world.

    Very happy with the investment and craftsmanship work. Worked well upon use. Really happy with the capacity increase. One of the things with the P365 is you want it to be small but lacks in capacity. MagGuts let’s you increase capacity and still keep your gun concealed.

  154. Ron (verified owner) –

    So far so good, cycles normal, easy to install. I saw that some said it didn’t hold two extra- it does the last round is tight. As far as the sharp edges, it’s not really “sharp” because it’s plastic. It is a little pointy though, and yes a slight buffing and rounding of the two corners with a Emory board (fingernail sander) made it smooth and a great fit. Yea a lil pricey but worth it IMO. Will buy one for all the mags we have. Not sure why industry hasn’t gone to flat springs yet.

    I purchased 2 of these for the standard 10-rounders that came with my P365 originally…they feed PERFECTLY and after just a few loads and unloads it’s easy to load all 12-rounds with just my finger tips! The amount of length they add is right between the factory flat baseplate and factory ‘pinky’ extended baseplate. (Not much at all!) It’s crazy to have 13-rounds of 9mm capacity in my front pocket! True these are a bit spendy but worth it in my book.

    Amazing product. Works great, looks great, still conceals great.

    Very happy with it. Easy install. No problems loading last couple rounds in it (unlike the stock 10 rounder). Seated perfectly with just the right amount of force. Feeds perfectly with no issues and, best of all, adds less to the handle length than the stock pinky extension mag but still has enough meat to get a good grip on. Makes it pefect for pocket carry. Will definitely buy another for the other stock 10 round mag that was included.

    Very easy install, and great reliability so far. My only issue is the sharp points at the rear of the new baseplate. Like many have said, I had to file off the sharp points, now it feels great. I would like MagGuts redesign the 10 round baseplate and send the new baseplate to all the customers who ordered the first version.
    All in all, great product and have already recommended it to people with the p365.

    I got a notification that the order was processed, but never did get a shipping notification or tracking number. In the big picture of things, these didn’t matter. The product arrived in what I’d consider a timely manner. It installed without any problems. Loaded my 12 rounds into my, formerly, 10-round magazine with no problems. I haven’t shot it yet, but once I do, and if all goes well, I’ll be ordering a +2 kit for my Sig 12-round magazine.

    I have had Magguts in my P3AT and Kahr P380 for some years so I know how well they work. I also have one in my P365 12 round mag and bought the latest for my P365 10 round mag. Well built and I have never had a failure with them.

  197. Lloyd Elliott (verified owner) –

    I bought for the P365 10 & 12 round mags. They work great! I managed to install the spring backwards in the 10 round mag. Consequently the brass bead does not center and you can only get 11 rounds in.
    Fortunately customer service recognized my mistake and once corrected all is well.
    2 additional round in each mag and I can’t tell a difference in the grip length.
    I will be ordering a few more soon.

    Great product. I’m glad the 10rd flush fit mag didn’t get skipped in these spring kit offerings. My wife carries flush fit mag because she needs a smaller profile handgun to fit her body type and clothing style. She also prefers to carry flush fit mag for backup because it’s easier to conceal with women’s pant pockets. So I got her two of these. Now she has 12rd flush fit mags for standard Sig P365. Awesome! I’m considering carrying one now.

    Great service and communication.

    Two-day delivery. We are in the same state.

    Installed easily, although the spring has a lot of spirit.

    Mag baseplate on the 10 rounder is just a freckle longer than the factory one, enabling me to keep my little finger on the mag during firing. I couldn’t do that with the factory mag plate
    Saw a couple of reviews mentioning initial small problems with jamming. Duplicated the conditions, but couldn’t induce failures.
    After messing with the mags and leaving them loaded for a week, I could actually get the last 2 rounds in the mag without a mag loader.

    I have an optional factory 12 round mag. It works fine, but it can be a bit obtrusive when sitting if carried OWB.

    I absolutely cannot get the last two rounds in that one without a mag loader. I haven’t touched it since I got the two converter kits for the 10 mags.
    I may get the kit to convert the 12 round mag to 14 rounds in the near future, just because of the shorter extension on the baseplate.

    These fit and look very much like the 10 rd magazine with flat baseplate that comes standard with the Sig p365. Would have preferred a “pinky” extension, but I can still get a better grip than the original which I expect wouldn’t have gotten much use.
    The extra capacity just blows my mind 12+1 in a “pocket” pistol, outstanding! Installation was a snap, quality, function, etc., all good. I converted 4 of the 7 mags I have, so the red followers make it easy to tell them apart.

    I’m a big fan of MagGuts+1, and I have been using them in some of my CCWs including G42, G43, and LCP. They all have been working reliably as designed. So, I was hoping that these MagGuts+2 for the P365 would also work. Nope, it was not the case. I fired 84 rounds of HST 124gr with two MagGuts fitted OEM mags and I had 4 fail to feed malfunctions. My P365 with the two stock mags had not had any malfunction with Federal HST or other JHPs. Unfortunately MagGuts for the P365 are not as reliable…

    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.

    A premium product with excellent materials and engineering. Fit, function and reliability are 100%. My order was efficiently processed and shipped. I rate these 10 round +2’s at a low 3 due to the sharp corners on the rear of the base plates. They come to a sharp point that then gouge the base of the palm in recoil. I used a 100 grit sand block to round off those sharp edges and it took away their “bite”. Given the premium price this is an oversight on the base plates that should have been caught at the line level and corrected prior to placing them on the market. They are in contrast to the correctly radiused rear base plate corners on the 12+2 units that I purchased. One other point. The directions refer to an installation video on MagGuts website. There is no video posted for the Sig P365 for those that may have difficulty with the directions on the card in the package.

    Outstanding products AND service! I’ve installed 30-40 MagGuts kits and they’ve all worked flawlessly and even increased reliability in my Kahrs (stopped the nosediving of the top round that Kahrs are known for) and maintained the reliability in my other guns while adding capacity. I was excited when I heard they had ventured into double stacks with the P365 – I’ve now installed maybe 15 of these kits. I got cocky about my tenth one in and let a spring slip out during installation which caused it to deform (the only issue I’ve ever run into with one of their kits) – they promptly sent me a replacement as part of the warranty despite me acknowledging it was my error.
    I use these daily and recommend them to others.

    Product was easy to install and arrived ahead of schedule. Will know more regarding performance after a trip to the range. Product adds about 1/8 inch to the overall length of the flush mag, which is more than an acceptable tradeoff for the increased capacity of two additional rounds. Back edges of the base plate are sharp and need to be rounded off with sandpaper so as to not dig into shooters hand when gripping the firearm. Took about 30 seconds to fix, but for the price should arrive to the customer already smoothed out.

    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.

I haven’t fired the pistol yet to confirm performance but have loaded rounds & ejected rounds successfully.

    I have ordered 3 of these and they are great. I keep them stored loaded and over time they are still reliable and have not had a single issue. The only problem I experienced is with the +2 kit for the 10 round mag. The corners of the base plate dig into my hand. I took a file lightly to the corners and it is very comfortable now. The +2 for the 12 round mag did not need any minor filing/sanding. The base plate adds less than 1/4 inch to the length of the flush fit 10 round mag. Great products

  313. Anonymous (verified owner) –

    The changeover was done is less than 3 minutes. Haven’t taken to the range yet, but it does load/unload 12 rounds. My only suggestion is to develop different magazine base plates. The P365 flush base plate doesn’t allow for the pinky finger to grip the magazine. This is also true of the MagGuts replacement. I’d like to see an extended base plate, similar in size to the P365 extended plate.

    Works great! Turns my p365 into what the XL would hold just by installing the MagGuts +2. Very pleased with this product. Can’t wait for them to come out with one for my Smith and Wesson csx!!

    Almost as much firepower as I had in a G19! Having 13 rounds in a pistol that fits in a pocket is a game changer. So far, I’ve only fired about 200 rounds and hand cycled close to 1000–not a single malfunction. I should have bought Magguts a long time ago!

    Does exactly what it says – somehow fits 12 rounds despite being shorter than the OEM 10 rounder with a pinky extension. The only issue is that the rear bottom corners are very sharp against your palm, but they’re easy enough to file down.

    I ordered what I thought was the +2 for the 365X but actually was for the regular 365. I reached out to them and he said just send it back and he would replace. Just got my replacement as promised. Great service and a great product. Highly recommend them!

    When I finally got to the range to use the MagGuts for my four magazines in my Wilson Combat Sig P365 they fed like a dream. The range-master also shoots the Sig P365 and he is now interested in MagGuts.

  350. Noah (verified owner) –

    Very convenient way to get a few extra rounds. It’s roughly the same size as the factory 10rd with the pinky extension, but more comfortable and better capacity. Would recommend.

    The Follower has a front cant that is close to tilting out, returned at my expense with no problem. All correspondence is done by email no live help.

    • admincorso (store manager) –

      The MagGuts follower appears to fit a little differently than the factory Sig follower. This is normal. Ours is a patent pending design that has no front skirt (but instead an attached flat spring) and is part of the reason we can get 2 rounds more in the mag than the factory does. It cannot come out of the top of the magazine and works perfectly. Looks different…works great. Our bad for not explaining this well enough to overcome your perception.

    I have bought MagGuts magazine insides for a while now. This is my third or fourth order, and I have never been disappointed. The product works right out of the box, and never disappoints. It is a reliable way to increase magazine capacity and who doesn’t like more! (unless it’s taxes.)

    What more can I say that already has been said before. It improves the OEM magazine by 100%. I can now load 12 rounds by hand where before I needed to use a Maglula loader to completely load the 10 round magazine. Also it is much easier to seat the full magazine in the gun now. Oh, the gun functions 100% with several different brands of bullets.

  369. Sean (verified owner) –

    I was amazed how tight the OEM magazines are for the Sig P365. I couldn’t load the last round at all. Some folks have said on YouTube and other places it’s because some of us are weak. That’s patently not true. These mags from the factory need a lot of break in time. Too much honestly.

    I researched these MagGuts springs and innards quite a bit. Yes, a few folks had issues and yes, the floor plate still has points that need sanded off (MagGuts folks, you listening?) but overall, it really works. The extra rounds for me are a bonus, not the reason I purchased a set. I can now load not only the original 10 rds of 9mm by hand in the OEM 10 Rd magazine, but all 12!

    Fix the pointy floor plate issue folks. That’s my one and only complaint about these. So far, well worth it.

  370. gerrit p. (verified owner) –

    Great product, easy to install and really adds two additional rounds to my 10 round magazine. The original magazine actually has a deficient spring that caused malfunctions when loading to 10, the max was always 9 rounds to reliably cycle. Now with the Magguts spring it reliably cycles 12 rounds.

  371. Frank Rollberg (verified owner) –

    Very nice!!

  372. John P. (verified owner) –

    Boom. These are better than the OEM 12 round Mag. The 12 round OEM Mag does NOT allow the 12th round due to a problem in manufacturing. But, the 14 round Magguts fixes that problem.

    Excellent product and fast shipping as always. I have these in all of my P365 mags (something over 20). Additional ammo is always desired in a carry gun, and these provide that along with confidence that they will work. I’ve been using MagGuts in several different models of guns for years and they’ve always been flawless – and in some cases even improved the reliability over factory internals (I’m looking at you, Kahr).
    Note that these springs have an additional “coil” over previous versions – I initially thought that the 12-to-14-round springs had been mistakenly put in the box, but saw where those had also grown another “coil.”

    No matter what I did and I enlarged the hole in one of my pinky extensions the base pad would not lock in. I have sent them back for a refund I bought a set of Armory Craft base pads that match my Wilson Combat grip module and they won’t secure. Really disappointed

    • admincorso (store manager) –

      These P365 conversions require the use of MagGuts bases. The bases are part of the system along with the spring and follower that allows +2 with almost no size increase.

  430. Valerio H. (verified owner) –

    Delivery was faster of what I anticipated. Very simple to assemble. Function and resistance feels the same as the original spring. Loading the magazine doesn’t feel any different from loading with the original spring (although they are 2 extra rounds). Went immediately to the range and ran 200 rounds through that mag flawlessly. Will keep using it at the range until convinced 110 %. At that point will start carrying it in the gun and will purchase another one ( for the 15 rds mag). I call it the “magic spring” and love this invention!

    After struggling for 30 minutes to get the spring in and baseplate on I discovered the baseplate will not lock in place no matter which way I put the spring in. In addition, the poor fit of the follower leaves me doubting the reliability of the magazine with these internals. I only use OEM Sig Sauer magazines. I feel that I have wasted my money on these and will not buy any further magazine internals of this type.

    Installed very easy and functions well. I would’ve given 5 stars, but there is no texture on the polymer base and there are extremely sharp corners at the rear of the baseplate that digs into my palm. I had to file these points down. At $34 each, these kits are as expensive as a new factory magazine. I really expected perfection for that price.

    Bought 2 of these for both 10 rnd mags that came with my puny little 365. After figuring out the direction of the oddball spring and how it goes into the magazine it clicked into place and I immediately tested the new capacity. 12 went in, Excellent! Also purchased the 12 round +2. Head to the range and got fantastic results. The 2 10 round, now 12, had zero issues. Not a single FTF or FTL. Perfect.

    Installed quickly. Appears to be a solid choice to extend the magazine capacity from 10 to 12 rounds in a standard P365 magazine.

    I have a Sig P365 with 10rd mags I’ve put 300 rounds through two mags and no issues yet. Really cool how they’re able to stuff 2 extra rounds into an already very small magazine. Guys with a lot more gun experience than I are even baffled by it. The only disappointing thing is that once the guts are in there, you can’t add a pinky extender.

    Great product, better than stock. The only problem would be the sharp edges on the back. I had to sand those down. Perfect otherwise.

    Very easy install. Love the red reciever and the little tab on it that makes it easier to verify an empty mag and load that first bullet.

    Not my 1st time purchasing, I got 12+2 & 10+2 about 2 years ago, maybe longer. 10+2 I used mostly until spring compacted or something, it’s shorter than the new one. Old 1 started jamming. Until then it worked great, 12+2 still working great but then again I don’t leave it loaded unless at the range.

    Worth every penny! I had a little difficulty putting everything together but in the end, it came out great!

  521. Kyle A. (verified owner) –

    These are a must have fix for Sig’s shoddy magazines. Feeds more smoothly and holds more rounds… whats not to like? I wish i didnt need to buy these but my poor p365 deserved better.

    Your products are the best, and I have several different mag kits at this point.
    I only wish you made kits for more guns…… I will always put your kits into any guns I have that you make a product for

    Great product, I would like a medium extended base plate for the Sig 365 since this is a small handgun but very well engineered product!

  526. Jadyn R. (verified owner) –

    Works exactly as advertised, I would happily recommend these kits for anyone who owns a Sig p365

    I would like the pinky extention to be the same as the one that came stock.

  530. Robert J. (verified owner) –

    Fast shipping, good communication, and good instructions. And they work. An amazing upgrade to an already amazing pistol.

    These are crap, the design of this chunky square baseplate doesn’t flow with the lines of grip of the gun creating a nasty sharp edge. Deep red grooves in palm after firing a single mag. These need to be retooled to fit the handgrip with tighter tolerances and better transitions from grip to mag. Need a v2.

  535. James D. (verified owner) –

    I had a bit of a time getting them in right but they are awesome i am 100 % glad i bought them.

    awsome company

  539. Jonathan K. (verified owner) –

    Simple to install, fits two extra rounds as advertised. Haven’t had a chance to shoot with it yet. AND it gets rid of the rattle!

  540. Anonymous (verified owner) –

    Works as advertised, no jams, weapon always locks open when empty. Easier to load mag than original sig mag.

  541. Dr Don H. (verified owner) –

    Well designed and fits like advertised.

  542. Robert N. (verified owner) –

    It’s absolutely necessary for these Sig mags, feeds and loads so smooth!

  543. Edmond F. (verified owner) –

    Went together easily and had no problems stuffing the extra two rounds in it. Haven’t shot it yet, but the tension feels right and I don’t think I’ll have a problem with it at the range.

  544. Jimmy J. (verified owner) –

    Both kits were easy to install and worked perfectly as advertised. Will likely buy more kits to convert my other msgs.

  545. Jack Z. (verified owner) –

    Possibly a little over-priced for what it is, but what it is is perfect. Easy install, feeds/works perfectly. Except for the slight visual differences (baseplate a couple mm thicker, black in my case, I had coyote tan, and a red follower) you’d never know it was modified. Great product.

    Easy install and reliability and feeding are like stock springs. Highly recommend for p365 owners!

    One extra round might mean your ass in a bad situation when you get selected to be a victim. One thing that this product allows you to do is. Get a couple of extra rounds and still maintain a low profile on your magazine. Extended magazines when you bending over. Tend to poke out and let someone know that you have a firearm.

  552. Theron Patron (verified owner) –

    I like this kit.

  553. Anonymous (verified owner) –

  554. Matthew (verified owner) –

    Purchased 2 for carry – 10 and 12 round versions for SIG 365. Quality product, easier to load, easier to get that last round in and so far, flawless. An extra 2 rounds makes a material difference without impacting concealment or reliability. Highly recommend and purchased additional units for all my mags.

  555. Jeremy M. (verified owner) –

    Fast shipping! Priced great! Will be buying more.

  556. Jarad K. (verified owner) –

    Product done the job. Still deciding if it’s worth the price. In the end I now basically have a 100 dollar magazine. But I like having a 12 round magazine in a small package.

  557. Victor A. (verified owner) –

    Worked as it should

  558. Brandon (verified owner) –

    Thanks to some commentors that recommended a nail file to slightly round off the back corners. Same capacity now as my XL in the smaller package.

    I’m a mechanical drafter by trade. One of the basic rules of design is if whatever you are making is going to be handled by someone, it’s courteous to put a round or fillet on all sharp edges. Love mag guts but the baseplate needed 10 minutes worth of sanding for a comfortable grip and comfortable carry as the sharp edges can be unpleasant. Hoping this review catches their design teams attention as such a simple fix to the molding would improve the design a lot. Otherwise a flawless design and fantastic upgrade. The baseplate is a little smaller than the pinky extension and a little bigger than the flush baseplate. It ends up being about 3/8″ give or take shorter than a factory Sig 12 round magazine. Simply amazing.

    Maybe I’m doing something wrong but it doesn’t seem to work. The loading piece will not stay in place no matter what I tried. Would definitely not recommend.
