Sig Sauer P365 +2 for 12 Round Magazine

(294 customer reviews)


This conversion reliably turns your Sig P365 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 (about 3/32″) and no impact on concealment
  • Easy to load
  • Reuses the OEM magazine sleeve
  • OEM – like fit and feel
  • Highest quality spring and component materials used.
  • Cutting edge magazine technology [patent(s) pending]

Not compatible with the X or XL models.
This item is not available for shipment to California.

  3. Mark A. (verified owner)

  4. Thomas Gardner (verified owner)

    I have used Magguts in my Smith Shields for some time with excellent results. When they became available for my current carry Sig p365 I had to order. Shipment was quick and reliability was excellent.

  5. Dean Norby (verified owner)

  6. Anonymous (verified owner)

    Works great and does not any noticeable length to the mag. Highly recommended.

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

  18. John M. (verified owner)

    Works great. I plan to get another for the 10 rd mag.

  19. Michael A. (verified owner)

    Does what it is supposed to do. A little harder to install then I would’ve thought but not a problem. Feeds gun flawlessly.

  20. Richard (verified owner)

  21. 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.

  22. William G. (verified owner)

    Work just as advertised

  23. Mel D. (verified owner)

    I thought the p365 12+2 is the same for the p365xl 12+2 mag. It’s not the same, so returned it. Would be great if Magguts could supply the shipping label and deduct the return shipping from the purchased item. Most USPS won’t accept anything that has to do with a firearm.

  24. Anonymous (verified owner)

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

  25. DAVID M. (verified owner)

    I don’t know how to give higher praise than to order more, which I will be doing.

  26. Fernando C. (verified owner)

  27. David M. (verified owner)

    I bought a single P365 12 round conversion to test, though I had little doubt that it would run properly having used their products in the past with success. I found the conversion was straightforward as advertised and simple to do. Though would advise the use of a vise as a third hand to gently hold the magazine body to assemble. I tested it as soon as assemble and it functioned perfectly even with self defense ammo.

    Spring catches on gap in mag & full msg causes “stretch” on mag seating. Hard to get mag to lock in. Interested to see how it cycles.

  33. Camden M. (verified owner)

    Wow! Almost the same capacity as a G19! This is awesome!

  34. J.F. (verified owner)

    It took me a little while to get them installed, due to arthritic hands and probably my age (86). However – they work perfectly in my Sig! Now my Sig 365 can be pocket carried with 15 rounds of protection. Extremely happy with my purchase!

  35. Dale (verified owner)

    Easy to install, looks good, minimally adds to length of magazine. Functions great, took to the range and fired 100 rds without out a single issue. Great product.

  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)

    Great product easy installation . Great upgrade for the P365

  38. William Key (verified owner)

    WOW 2 more shots and hardly any increase in size. Guts were easy to install too.

  48. Josh H. (verified owner)

    So far so good!! As long as they stay reliable, what’s not to like?!?!

  49. Alan C. (verified owner)

    I’m only giving this a 3 because I just received this. I haven’t had time to hit the range yet. What I can say is it is easy to install and seems to work and cycle through as it should. Now what I really like is the 1/4 extra just fits my hand like a glove. Seriously feels awesome as that was a unexpected pleasure so to speak.

    I purchased this because I just don’t like the size of the XL as I like the normal P365 in size. This just rocked my world in a great way. Thank you guys for making my little Sig P365 capable of 14 plus 1. Life is good. 15 rounds in I mini. Hope I never need it but I now have it if needed.

  50. Michael Brown (verified owner)

    Easy installation. It took longer to eject the round in the mag than it took to install the Magguts. Works perfectly. This made for my 10th Magguts in my EDCs, and all have performed perfectly, some older ones having each gone through about 5,000 rounds. I’m anxiously awaiting the Magguts for the 15 round mag.

  51. Daniel Brown (verified owner)

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

  58. 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.

  65. Christian H. (verified owner)

    The product works as advertised adding 2 additional rounds, a few issues I see are 1. There seems to be some looseness to the mag where you can hear the spring/ammo moving around. 2. Because of the spring being squared off it looks to have a chance to stick out of the little corner cuts of the magazine causing the spring to not move and possibly causing a malfunction. I have yet to take it to the range to test.

  66. Larry (verified owner)

  68. Edgar Flotte (verified owner)

    It doesn’t work well I am getting nose dives and not feeding

  69. Alan Hull (verified owner)

    Works exactly as advertised. My only issue is the spring steel has sharp edges and has a lot of tension. When trying to install the spring and compress it into the magazine, it got away from me, and sliced the tip of my thumb as I was trying to compress it. Recommend wearing gloves to install. Other than my mishap, it works great!

  70. Donovan (verified owner)

    Great price and a fantastic product! Easy to install and you have to love two extra rounds in a compact platform. I will definitely be purchasing more for my 10 and 15 round mags soon.

  71. Michael (verified owner)

    Recently I decided to switch my daily carry to the Sig Sauer p365. The main reason was for capacity. So it only makes sense to use MagGut’s spring and follower kit to give me even more capacity in such a small package. Installation was easy and all four of my 12 round (now 14) magazines have worked flawlessly with their product installed. It’s easy to get a full capacity 14 round mag in my gun with a round in the chamber no problem. Shipping was fast and well packaged. I highly recommend this product and I’ll buy more as I buy more magazines.

  72. Robert (verified owner)

  73. Blake B. (verified owner)

    Very happy with this kit! Awaiting the release of the plus 2 for the 15 round magazine!

  74. Raj (verified owner)

    Love the product, I’ve bought 7 of them so far. I preferred the old hard plastic packaging so that I could store my original mag spring in it, but I’m sure the new packaging saves money.

  75. Anonymous (verified owner)

    The Sig P365 was looked at as an engineering marvel anyhow. The 12rd magazines make the tiny tiny pistol more comfortable/accurate. Being able to put 14+1 in a package that small (3/32″ addition to the height is negligible) and have it function as flawlessly as stock for a mere $34 additional…just makes sense.

    I’ve put about 100 rounds through the gun using the new guts and so far no malfunctions. Seems to work great. Amazing to get 2 more rounds with such a tiny increase in baseplate size. Very impressed so far.

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

  83. 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.

  84. Mclean G. (verified owner)

    Made reloading easier which was surprising since there’s such little room taken up to add the two rounds, put about 200 rounds down on it so far and it cycled flawlessly, I will be buying more

  85. Adrian L. (verified owner)

    Shipping is super fast and easy to assemble. Happy customer ordered 2 more!

  86. Michael A. (verified owner)

    Worked as described. Super easy install.

  87. 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.

  88. David Smith (verified owner)

    bought 365xl mag guts to take it to 14 rds. (from 12) The last round will not feed into the chamber. Slide locks open with one round remaining. Doesn’t matter if there are 14 rounds loaded or 2 rounds loaded-slide locks open with one round left in the mag.

  93. 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.

  94. 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.

    I had an incident where driver on drugs accused me of following him as he was parked in the middle of the street on a curve. He jumped out and called me a racial name for a white male and threatened to harm me, while I was taking my son to the park. I responded with a tactical racial remarked as he was already approaching my car with intent to fight, at which he then changed his attack plan. He and the other male were somalian, and I was in a south Seattle district. Little to say, they never knew that I had a weapon (p365) I can easily draw and put into work, but that I also had 28 rounds in only 2 mags.

    Super easy to install. I’ve had the new springs in 2 12 round magazines for about 2 weeks now, and fired about 550 rounds shared by both. Still feeds like the original. Where I have to say these things shine is reloading. Every single round that has been loaded in has been a breeze. With the original spring I would fuss on the last round of each magazine. It was a pain! Now the 12th round goes in easy, as well as the 13th and the 14th. Haha. Getting more for my p320 next!

  130. Jonathan W. (verified owner)

    Nearly the price of a brand new OEM mag, but does function perfectly. 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.

    Excellent product, mag feeds well, slide locks to the rear. Would 100% recommend to anyone

  132. Anonymous (verified owner)

    Order was efficient and receipt expeditious. Quality superb. Install straight forward. Some say the price is near the cost of a new mag for a +2 gain. I say for the carry niche it fills, l got a bargain.

    Ok, I got to admit, I was leary at first, but this popped in with minimal effort into my p365 12 rd mags. Amazingly it now holds 14 rounds. Whats even better is before the install, my pistol would not hold 12+1 due to a fully loaded mag not locking in with a bullet chambered. Now its no problem, 14+1 is easy peasy. Slide even locks back on the final round and the mag is actually easier to load. Ill be buying more mag guts for sure. Super happy! A 15 Round P365, look out hellcat.

    If you have a p365 you need this! If you want 2 more rounds, this is the best way. I carry the 12 rnd and now it’s a 14 rnd. There is no sacrifice in the length either. Perfect.

    They solved the problem of Sig’s pathetic attempt at designing a 12 round magazine. Sig should be ashamed of themselves for putting out such an inferior product. Mag Guts not only fixed the functionality, they improved upon the the design by offering two more rounds. Well done!

  150. Edward Maroti (verified owner)

    I’ve bought 4 for the p365 and had 2 for m&p shield. I feel there great and never had a malfunction with any of them. A fair price for a plus 2 with really no length added.

    • admincorso (store manager)

      The converted magazine should not be tight at all. In fact it should be easier to load the two extra rounds than it is to load an unconverted magazine. We sent an email to you from support with a plan to get this resolved.

  159. CHARLES M. (verified owner)

    bought 10 & 12 round magazine magguts- 12 round + 2 is very good- 10 round round +2 should have longer base plate- maybe a 1/4 inch longer. Both have follower with metal attached to underside- maybe a weak point- could it snap off???

  162. Scott M. (verified owner)

    Magguts made me feel like I bought a whole new p365 instead of “just” a magazine spring kit.
    Loading last round in my p365 tacpac 12 rd mag was very difficult.
    And even worse made it very hard to operate slide on a full mag, begging for a failure to load.
    Magguts maintains equal spring pressure whether round 1 or rd 12, and cal draw back alide on full 14 rds mag.
    Love it.
    Received quick, installed quick, works great.
    A no brainer.
    Wear safety glasses.

    Very good product. Time will tell overall. Follower with metal attached to underside – maybe a weak point-could -Could it snap off?

  164. Bryan (verified owner)

    One of them had the spring turn sideways, bend, and become unusable, feeding no ammunition, the second time I loaded it. I’ve stopped using both the 10 round and 12 round extensions because shot #2 is way more important that shot #12 or #14.

  165. Salvatore C Vieni (verified owner)

    Love this so much!!! Works flawlessly install was easy!

    I would greatly buy again if you did this as another kit that was +3 instead of +2 and def waiting for the addition to the 15 round mag.

    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

    After buying my first magguts for my Sig p365, I was amazed, now holds14+1. Super easy to load now and cycles perfect. 200 rounds and zero feed issues. Had to get a second one for the wifey! She’s happy. Happy wife, happy life. Lol

    I purchased 1 of these for the only factory 12-rounder I currently have…it feeds PERFECTLY and after just a few loads and unloads it’s easy to load all 14-rounds with just my finger tips! These add zero length, when compared to the original, after installation. It’s AWESOME to have 15-rounds of 9mm capacity in such a small package on my belt! I actually rarely belt carry my P365 as I’m a full-size fighting handgun kinda guy but it’s ALWAYS nice to have options! I use my new MagGuts 14-rounder as an off-pocket backup mag. True these are a bit spendy but worth it in my book.

  190. Ron R. (verified owner)

    Amazing product! I purchased one for all of my 365 mags – except the 15 round. Please create one for it soon!

  191. Christopher H. (verified owner)

    It’s great that I now have two more rounds in my twelve round magazine with virtually no extra length added. My only problem is the rattle in my magazine when I have the fourteen rounds in it. It loads and functions fine. Just has a rattle.

    10/10!!! looks factory and holds the slide back every time! Someone was saying that the rounds get stuck unloading rounds by hand but i find that factory mags did the same. I’m going to buy another 12 rounder just to make it into a 14er 😀

  198. Alan G. (verified owner)

    So far so good. This gives me nearly the same capacity of my P320C in an unbelievable small package.

    Amazing! Replacing the follower, the spring, and the mag base takes about 2 minutes. Now my CC P375XL holds as many rounds as my SW MP 2.0 9mm. Love these extenders!

  220. Sheri W. (verified owner)

    I had high hopes for this product with all the positive reviews on here. However, it was easy to assemble and once assembled if you try to use a mag loader the front of the follower pops up and out of the mag and its sitting at a 45° angle which makes it untrustworthy in my opinion. The follower should have some sort of positive connection to the spring instead of just being a separate piece that rides the top of the spring. This allows the follower to pop out too easily.

    I inadverdantly ordered the kit for the P365 rather than the P365XL…the baseplates for these are different, but I was sent the proper baseplate at no charge…. excellent service and an excellent product!

    Apparently, they’re two (2), different 12 round magazines for the Sig P365, (non-X, non-XL), standard pistol. I tried for 45 mins. to assemble this mag to no avail. Purchased an extension insert for a P365XL 12 round mag previously, and it works perfectly. Be sure you know what mag insert you are purchasing, and it’s for the correct UPC or product number magazine from Sig. The follower and spring in the one I purchased keeps jamming and the spring is now bent into all kinds of weird shapes. Never fit properly. BTW, I’ve done trigger tunes, sear filings, rail lapping, MSH adjustments, etc. and have shot pistols and rifles competitively for over 20 yrs.; not a newbie at this.

    My “go to” mag for the Sig p365 is the 12rd. The Magguts kit is like icing on top of the icing on the cake, 14+1, wow!
    Simple install, no hype, they do what they are supposed to.
    Sig magazines for this pistol cost $42-$43, they are salty. With the addition of the Magguts kit
    (I bought 4 right from the start) they have become the most expensive mags I have ever owned…in my life! Lol
    To me, the cost is worth it, no complaints. Great product, I will buy more!

    A gamechanger for The Gamechanger!
    The Sig P365 was already considered a gamechanger for concealed carry with its 10 or 12 round mag capacity in such a small pistol. With a Magguts kit in the 12 round mag the P365 offers the ability to carry 14 plus 1 in a platform that was limited to 7 or 8 plus one a short time ago.
    The kit is easy to install (it takes me longer to hand load the mag than install to the kit) while somehow making the mag easier to load!
    Quick delivery & excellent customer service/support makes Magguts a pleasure to do business with & this product is a truly remarkable innovation.

  268. Bruce (verified owner)

    Works Great. Love the fact that I got 2 extra rounds per mag for my P365. Cost is the reason for one less rating score. $20 a spring would be about right! Not $76 for 2 springs with shipping and tax.

    The spring and follower appear well made from good quality material. The installation of the spring was straight forward and it holds the two extra rounds as advertised. I have not yet been able to test the magazine because of the bad weather. I will follow up later after I test it.

  272. Michael B. (verified owner)

    Very easy installation. Best way to add rounds without getting a lot bigger mag. I think the folding spring is the wave of the future. There is no way it can get “ coil wrapped” like almost all other coil springs in most magazines. Definitely a winner!’
