MagGuts +2 Conversion for Sig P365 Standard 12 Round Magazine (Not X/XL)

(652 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

    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.

  52. Chet P. (verified owner)

  57. Josue V. (verified owner)

    The terminations looks pretty good and the dimensions are awesome

  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

    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

    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.

    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!’

    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?

    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.

  357. Jason (verified owner)

    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!

    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.

  386. Hardy C. (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.

    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.

  397. 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.

  398. Daniel Swanson (verified owner)

    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!

    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, but the reliability has been maintained.

    Difficult to install, may require several assemblies before the correct posture is achieved. Cut my hands up in the process. Rather expensive. Easier to load than the original magazine. It took a long time to install. If you bend the spring then it becomes extremely difficult to install. If the metal pops out and bends itself, Lord have mercy.

    Be aware. This magazine kit is for a magazine with the two piece base plate. I’ve changed my P365 grip module to a P365XL grip module, and my magazines now need the one piece base plate. I ordered the correct one a while ago, and it’s brilliant! The man who invented it is a genius.

  492. Keith (verified owner)

    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.

    I was skeptical in the beginning but, after 500+ rounds of mutiple types and manufacturers, without a single failure or issue, I would give this an A+ buy recommendation.

  547. Ryan (verified owner)

    Installs easy and utilizes the factory grip extension, so you retain the excellent factory magazine grip texture. Function is good but, when fully loaded, it rattles very loudly.

  548. Charles R. (verified owner)

    The MagGuts +2 conversion for the P365 12 round magazines, does in fact allow two additional rounds in the magazine. The conversion is more difficult than it would seem…the follower has an attached spring that seems to be more of a guide for the folded MagGuts spring. The attached point of the “guide” results in a bump that is prone to catching the top fold of the main spring. This catch point is mentioned as a precaution in the assembly instructions. If the folded spring end catches the bump, things don’t work as they should. It would seem that bump could be trimmed so as to not catch the top fold, or the leading edge of the top fold could be chamfered or rounded to prevent catching.

    Wish I could upload a video of all three! The 10 to 12. The 12 to 14, and the 15 to 17! All with a round in chamber making them: 13, 15 and 18! All fired FLAWLESS! Thank YOU!!!

    EXACTLY as advertised, and recommended by several Youtubers – quick shipping, and installation was almost too easy. The video provided by MagGuts was spot on, I did 3 of them in about 10 minutes. Feeds great, excited to put many rounds through. What a thoughtful product – and virtually NO change in the mag, yet I get another 2 rounds. HIGHLY RECOMMENDED!!!!

    Flawless so far. I’m so impressed with such a small package holding 14+1 of 9mm. Going back to the range this evening to hammer away at another 100 rounds. Very happy with this.

  556. Garrick (verified owner)

    Took it to the range yesterday for the first time. Ran about 350 rounds through it. It ran PERFECTLY. Not a single malfunction, and the slide locked back every single time after shooting the last round. What more could you want? 14+1 in a gun this small, and it runs reliably? Couldn’t be happier. You won’t regret the purchase. Thank you, Magguts for taking my money. Haha

    This is the 2nd ser The bought. The 1st one was for the 10 rd mag. I tried it w/ 900 rds before use to carry. Now I got the 12 rds mag gut and after 90 -100 rds am confident to put in service and carry. Never had any problem with either. They run flawlessly. Now I carry the P365 w/14 rds and a spare 12 rds mag. Very satisfied. Delivery was away faster of expected.

    It was easy to install , went to the range and tested it. It worked flawless

  572. Jeremiah S. (verified owner)

    Easy install and no misfires so far. Exactly as advertised and worth the cost to carry an extra couple rounds in my EDC. Critics say they could buy another mag for the same price, and while that’s true for the range, this is for my personal carry weapon and totally worth it!

    This is the fourth spring I’ve brought.
    I brought three for my p365XL.
    All worked as described.
    I later decided to by this one for my p365 twelve round mag. This is my wife’s home defense gun.
    All mags now hold 14 as described.
    It is easier loading the 14 than the 12.
    There was a little difficulty and frustration level with installing the springs in all the magazines. Don’t give up you can do it. I did have to walk away for a little bit and take a break and rethink what was going wrong. I do recommend before actually putting the spring in, dry fit the base plate a few times before moving onto inserting the spring itself. But I got them installed correctly. I would definitely buy them again.
    Next is a recommendation from magguts reviews read reverse the order that they are in. Put the most recent at the top and old is at the bottom. I think most people would like reading the recent ones and not having to scroll for a day and a half to get to the most recent ones. Just my suggestion. Keep up the good work.

    Possibly a little over-priced for what it is, but what it is is perfect. Easy install, feeds/works flawlessly. 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.

    Customer service went above and beyond when I ordered the wrong P365 kit. Base plates were not right ones so they allowed me to exchange for the (X/XL) bases.

    Shipping was fast, and discreet. Installation took all of three minutes, and just as advertised, loading is easier, and two more rounds fit in a still compact magazine. I only bought one for my EDC, but after experiencing it, I will be buying this kit for all of my magazines.

    I accidently ordered the wrong kit for my std, 12 round magazines for my Sig P365. I contacted customer support, explained that I thought the bottom baseplate was the only difference. They said that was correct. So I sent the wrong one back, and they sent me the correct one free of charge. Class act company. So now I own (3) three Magguts kits for mt three 12 round mags. It`s a joy to do business with companies that conduct business with old fashion customer service. That`s rare these days.
