  1. Donald (verified owner) –

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

  2. Stan (verified owner) –

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

  3. Raymond C (verified owner) –

    It works

  6. Stan J. (verified owner) –

    Shipping was quick. Product seems to be of high quality. Installed with no problems at all.

  8. David H. (verified owner) –

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

  9. Anonymous (verified owner) –

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

  10. Ray K. (verified owner) –

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

  11. John (verified owner) –

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

  12. Mike (verified owner) –

  13. Peter B. (verified owner) –

  14. Ernest L. (verified owner) –

    It’s nice to actually get something worth what you paid for it.

  15. Steven B. (verified owner) –

    Ran two magazine loads to test with mix of ammo. Also left it sit loaded for a day prior. So far no mis-feeds, etc.

  16. Scott P. (verified owner) –

  17. Michael P. (verified owner) –

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

  18. Mark B. (verified owner) –

  19. Michael Martinez (verified owner) –

    Great product! Was waiting for something like this!

  20. Quang (verified owner) –

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

  21. Anonymous (verified owner) –

    Always quality that works from Magguts!

  22. Jose Lopez (verified owner) –

    Works great like all your maguts

  23. Robert Bailey (verified owner) –

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

  24. Robert G. (verified owner) –

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

  25. Kerry Coyle (verified owner) –

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

  26. Richard (verified owner) –

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

  27. Kee (verified owner) –

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

  28. Scott P. (verified owner) –

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

  29. William G. (verified owner) –

    Work just as advertised

  30. Kevin F. (verified owner) –

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

  31. Anonymous (verified owner) –

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

  32. Fernando C. (verified owner) –

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

  33. Dwayne H. (verified owner) –

    Like added rounds but would like extended grip too

  34. Anonymous (verified owner) –

  35. Camden M. (verified owner) –

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

  36. John S. (verified owner) –

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

  37. Ron (verified owner) –

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

  38. Mike Mueller (verified owner) –

    Great

  39. William Key (verified owner) –

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

  40. Jon Bowman (verified owner) –

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

  41. E.J. C. (verified owner) –

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

  42. Michael M. (verified owner) –

    Excellent product. Super easy to install

  43. Michael (verified owner) –

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

  44. Geno B. (verified owner) –

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

  45. Patrick M. (verified owner) –

  46. Alan S. (verified owner) –

    fits well easy to assemble

  47. YOUNG K. (verified owner) –

  48. Josh H. (verified owner) –

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

  49. Byron Ray (verified owner) –

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

  50. Gordon Weis (verified owner) –

  51. Orlando Gonzalez (verified owner) –

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

  52. Anonymous (verified owner) –

  53. Michael Brown (verified owner) –

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

  54. Daniel Brown (verified owner) –

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

  55. Vincent L. (verified owner) –

    Installed in minutes works flawlessly.

  56. Robert (verified owner) –

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

  57. John Benson (verified owner) –

  58. Oliver (verified owner) –

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

  59. Scott G. (verified owner) –

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

  60. Chase (verified owner) –

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

  61. Michael (verified owner) –

    Couldn’t be happier.

  62. Phillip LaFlamme (verified owner) –

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

  63. Joshua (verified owner) –

    Great product. Works flawlessly!

  64. David (verified owner) –

    Pretty cool product and so far it works well

  65. Michael G. (verified owner) –

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

  66. CHARLES C. (verified owner) –

    Order was correct and delivery was on time.

    Have not gotten them yet

  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.

    Feeds perfectly and loads with 12 rounds without a lot of effort, love it!

  78. William Trilk (verified owner) –

    Only have couple hundred rounds through them but 100% reliable and 12 do load easier than previous 10.

  79. Andrei Nicolau (verified owner) –

  80. Matthew S. (verified owner) –

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

    Gets 5 stars based on quality, easy to install and that I know it will work flawlessly just like the magguts I put in my Kahr CT380

  84. Anonymous (verified owner) –

  85. kay b. (verified owner) –

    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.

  93. Wade Hermes (verified owner) –

  94. Richard Dillon (verified owner) –

  95. David A. (verified owner) –

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

  96. Anonymous (verified owner) –

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

    Magguts deserves respect and business.

  97. Phillip L. (verified owner) –

    Great product. This is my third set of guts I love how it does not make my mags longer just ups the capacity. Brilliant!

  98. Philip B. (verified owner) –

  99. Derek M. (verified owner) –

    What an awesome design. Cycles flawlessly. People almost don’t believe me when I tell them this little magazine is packing 12 rounds of 9mm defense thanks to Magguts!

    Great!

  106. Matthew (verified owner) –

    Bought 3 of the Sig P365 +2 for 10 Round Magazines. After a few hundred rounds all three are functioning perfectly without any issues. It is amazing to have 12+1 available in such a small package. Well done.

  107. Edgar Alain Flotte (verified owner) –

    works excellent with all sorts of ammo including Underwood +p+ penetrator “boutique” ammo. A++

  108. Mac P. (verified owner) –

    These things are great. Easy to install, work great. A little pricey but what can you do?

  110. Kevin R. (verified owner) –

    Product works as designed. Loading is easier. 2 more rounds without added bulk, this is a win/win.

  111. GARY (verified owner) –

  112. PAUL E. (verified owner) –

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

  113. Ed F. (verified owner) –

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