    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.

    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.

    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.

  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.

    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.

  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.

  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.

    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.

  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!

    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.

    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

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

    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.

    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.

    Huge improvement. Far easier to load and better capacity

    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.

  179. David (verified owner)

    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.

    10/10!!! Looks factory and works every time! You might have to shave off some plastic on the back of the base plate as I did, it was protruding and digging into my hand. Just a heads up. WOULD Recommend

    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.

    A very practical mod. I’m very impressed with the quality of this product. Seems overpriced (should be <$25) but is well engineered, functions well, installs easily, innovative flat spring and components, good spring tension, and amazing form and fit to get 2 extra rounds. Much easier to load manually than OEM mags. Sharp corners are easily filed or sanded. Makes an already incredible pistol amazing.

    I was skeptical that this would work reliably and was pleasantly surprised after testing different ammunitions. Fed reliability and locked up and the only slight criticism I would have is something already expressed by others, namely sharp corners at the bottom of the magazine. I would suggest you polish these at the factory, as I have done at home.

    Love them, magGuts in all four of my sig 365’s . The extra rounds are worth it . they also catch slide way better then the 365 magazine spring does after last round . I bought two then another 3 more . I not only recommend them and have tested 300 rounds on couple of them no issues at all . Yes I feel safe having those extra rounds and with no extra length on pistol, I’m getting more . I actually use my ten round mags now lol. 😎 thank you sooo much .ARI

    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.

    Magguts is the first item to buy after purchasing your new pistol! Provided a kit is available for your make and model pistol. I have bought about 10 kits from them for various pistols I own. All worked as well or better than OEM. I just wish they offered replacement parts for their kits, as I anticipate needing replacement parts in the future.

    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…

    It adds a bit more length to the magazine than the one for the 12rd mag but in a way it’s better that way so now my used to be too short mag have a bit more to grip my pinky finger to.

    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.
