Sig Sauer P365 +2 for 12 Round Magazine

CVN039
(407 customer reviews)

$33.95

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.

  7. John (verified owner)

    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.

    In a pricey end but worth it

  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.

  52. Chet P. (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.

  131. Nicholas D. (verified owner)

    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.

    The first magazine I received had a weak spring that was causing issues. MagGuts was very professional about sending a replacement which has given me no issues since.

    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.

    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

    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.

    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.

  221. Kevin D. (verified owner)

    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.

    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

    Awesome!
    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.

    Outstanding products AND service! I’ve installed 30-40 MagGuts kits across various firearms 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.

    Over 300 rounds of assorted brass/reloaded brass, and steel case through the two mags that got upgrades and zero malfunctions.

    Early last year I purchased one 10 round MagGuts kit and one 12 round kit. The 10 round kit worked great and I love it, but the 12 round spring was pushing the base plate from the magazine and eventually did separate from the magazine. I tried to contact someone at MagGuts and did not get any response. I purchased another 12 round kit a few weeks ago thinking maybe the first one was flowed. I installed the kit as instructed and it too was pushing the base plate out from the magazine and shortly the base plate became separated from the magazine. I would like to talk to someone about this as I want this to work. If it will not work correctly I would like a refund! I would love for it to work please! May I hear from someone please? My contact information is as follows:

    Placed order (#044051) on 2/4/22. Still have not received product or any shipping info.

    Awesome Product! Skipping was fast. Like the look better than the stock 15rd.

  349. Riley L. (verified owner)

    Excellent product, nice having 30 rounds on me, in the Sig 365, the load a little smoother as well. Thanks Mag Guts!

    Turns your P365 into the highest capacity subcompact. Worth the money and will be buying more!

    Quality components. Easy installation.

  353. Richard Presel (verified owner)

    I ordered the wrong kits, I needed the 365X kits. I contacted Customer Service, I received a response very quickly. I was offered a trade; my bases for the correct ones. Great Customer Service.

    This conversation runs well, feeds ammo great, slide locks back perfect, thanks

    I was happy with the quality but couldn’t get a response back in regards to a return. I bought what I thought fit my magazine (p365x) 12 round mag but it was for the p365 12 round mag. I tried to get support from their website but was never contacted back. I am still within the 30 days of purchase and I’m only looking to return for the kit that fits my pistol. I will pay for shipping just make the return process easier plz.

    Outstanding quality and performance. Not a single failure with these components installed. I’ve ran Magguts in all my Glocks, Springfields, and now Sigs; never an issue with any of them. And now my P365 XL has 14 round mags at a fraction of the size of a 43x. Highly highly recommend!

    Very interesting spring

  361. mike thomason (verified owner)

    didn’t send the right kit for my sig p365xl

  362. Christopher (verified owner)

    Amazing product; spring works better than original Sig part.

  363. Steve J. (verified owner)

    I haven’t gotten out to the range yet but installation was a snap and I have cycled the slide and all rounds fed like they should!

  364. Jonathan (verified owner)

    Works well, was shipped fast easier to assemble than Kahr magazines but, the sides of the springs sharp for the Sig hence 4/5.

  365. Augie M. (verified owner)

    Excellent product. I have three mags with magguts springs in them and they all run perfectly. Will be buying a few more for sure.

  366. Kevin W. (verified owner)

    Easy to install. I ran 250 rounds through the mag without a single failure to feed.

  367. Cameron (verified owner)

  368. Stephen S. (verified owner)

    Works extremely well as I can now load to 14 +1 rounds in my P365

  369. Christopher B. (verified owner)

    Easy to install. +2 and a slick lookin baseplate.

  370. Keith H. (verified owner)

    I’m very happy with this mag extender! It’s only about an eighth of an inch longer than the 12 round mags for my Sig p365. Waiting to test it at the range with different ammo to insure it feeds well. I don’t doubt it works perfectly.

  371. Steve M. (verified owner)

  372. Murray L. (verified owner)

    Great product! Changed my P365 carry from 12+1 to 14+1 without any change in size. For $35 it’s a no-brainer.

  373. Mathew K. (verified owner)

    10 out of 10 not only do you guys offer a great product but your customer service is excellent! Speaking from experience

  374. Danny W. (verified owner)

    It works and keeps working like it should. My only gripe is the follower sticks up too far and sometimes interferes with reloading. Other than that … it is as advertised!

  375. Donald W. (verified owner)

    Assy easy, couldn’t get more than 3 rounds in mag

  376. Morry Lanera (verified owner)

    Great experience. Quick and accurate.

  377. Billy Turner (verified owner)

    All I can say is PERFECT!! It gets NO Better. Perfect on dry Cycle, Perfect on live fire, easy install, no additional length added, other than a “bump” at base which is not noticable. Thank You MagGuts for a perfect product!!

  378. Michael C. (verified owner)

    Order was processed and shipped very quickly and arrived in no time at all! Instructions for installation were clear and item was easy and quick to install. Need to test item out but happy so far!

    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.

  381. Slava K. (verified owner)

    After testing my mag with the new guts at a range I have full confidence to use it in my carry gun.

  382. Anonymous (verified owner)

    Easy to install, works great 👍

    Product is expensive. If there’s an issue, you’ll pay an additional $9 for exchanges.

    Putting the price of a plus-two mag extension at over $40.

    Ordered product in late February. Not getting support. Extremely frustrating.

    If I’m unable to get product support I’ll use all of my emails as evidence to contest the charge and get a full refund via my CC company. At which MagGuts can send me a prepaid envelope to get their parts.

    I repeat, extremely frustrating.

  384. Rocky Caceres (verified owner)

    I tested and worked perfect! It’s super easy to load, the only thing I didn’t like is the base plate is loose slide back and forth. I had to made a shim to keep it in place.

  385. Worth (verified owner)

    I had one failure to feed with the first magazine fired! Have not had any problems since then!

  386. Aaron (verified owner)

    Good products, backed up by great customer service. Initially I ordered the wrong magguts kits. I reached out to them and they offered to exchange it at no charge. Very quick response. I ended up just buying the bottom plates, I needed to make it work on my current setup. I also ordered two extra magguts kits(correct ones). So I now have 4 kits and 2 extra bottom plates(Incase I decide to change my bottom frame) which is great. 5 stars.

  387. Hardy C. (verified owner)

    These are amazing, and I recommend them to anyone- I even sent one to a family member! They work perfectly and a super easy to install! In less than a minute you can have 2 extra rounds!

  388. Anonymous (verified owner)

    Prompt deliver. Product worked as described.

  389. Jose H. (verified owner)

    The mag inserts appear to work as advertised. I received them within a few days of the order!

  390. George (verified owner)

    With the MagGuts +2, there is nothing smaller with 14+1 capacity than the Sig 365. Definitely worth adding this to several of your magazines.

  391. Paul B. (verified owner)

    So far everything is great! Works as described. Easy installation, fast shipping etc. Time will tell if this holds up and can be counted on reliably for EDC. So far I’ve put about 400 Blazer FMJ 9m range rounds thru with 115g and 124g — no issues at all. Very pleased … so far. Contact me in about a year to do a reliability feedback form.
    PS: Website could use some work. Need feedback on orders, cost, shipped status etc. etc.

    So far so good about 60rds in with my one example and will keep running it. Once I get a few hundred rounds through it, I’ll likely be ordering more for the rest of my mags.

  395. Ronald R. (verified owner)

  396. Steve G (verified owner)

    Looks like I may be buying another one.

  397. Thomas V. (verified owner)

    Worked as advertised. Took 12 round magazine and enabled it to carry 14. The Sig is a small package that now carrys 15 rounds of fun. We’ll worth it!

  398. Emil Ivanov (verified owner)

    These custom magazine springs caused my P365 to not to be able to re-load automatically. The issue is also known as “nose-dive”. When I switched back to the original springs, the issue went away. Very disappointing.

      The converted magazine should work perfectly. It sounds like something must be wrong. Please refer to an email sent from support to help you get things working as they should.

    I concealed-carry a Sig Sauer P365 every day, along with three 12-round mags—one in the gun and two extra—all with MagGuts springs installed. With one in the tube, that’s 43 rounds! From the factory, these Sig mags were very stiff, requiring a mag loader to fill them up. But, with MagGuts springs, it’s now possible to put even that 14th round in BY HAND—still not exactly EASY, but POSSIBLE! 😉 Love the quality workmanship, and the look of that brass retaining pin in the base plate!

  400. Robert Zabel (verified owner)

    Works great. Turns the 365 into a real powerhouse.

    Simple to install, done in 2 minutes. Haven’t been to the range yet to see how the function is. But I think all is good
