MagGuts +2 Conversion for Sig P365 X/XL 15 Round Magazine

CVN045
(77 customer reviews)

$33.95

This conversion reliably turns your Sig P365 15 round magazine into a 17 round magazine specifically tailored for the X and XL models.  The spring, follower, and base are replaced with MagGuts™ components while the magazine housing is reused. There is also a sleeve provided that matches the X/XL grip module perfectly. After installation, the sleeve is fixed onto the magazine housing and does not move. The converted magazine works in all versions of the P365 (standard, X/XL, and Macro) but mag sleeve included was designed for X/XL version. When used with the standard (not X or XL) P365 model there will be a gap between the mag sleeve and the grip. If used in a Macro, the sleeve is not used and there will be a gap between the base and the grip.
With this conversion you will get:

  • Reliable feed and slide lock
  • +2 capacity increase with negligible length change
  • Easy to load
  • Great fit and feel with grip matching texture on sleeve.
  • Highest quality spring and component materials used.
  • Cutting edge magazine technology [patented]

Sleeve included for the X/XL grip modules only.

This item is not available for shipment to California.

    Work great, good upgrade!

    To be honest, I have not yet installed / tested this… But I have full faith, as I have the 10 (to 12) and 12 (to 14) magguts installed in my P365/P365XL mags. Hence, I have no doubts about this 15 (to 17) version.

    Only down side is the damn price of Sig magazines, plus this, turns into $80+ each mag lol.

    This kit is somewhat more difficult to install than the 12+2 kit. The spring seems stiffer, which plays a role in the difficulty when trying to “accordion” the spring into the Magazine. Haven’t had a range session yet to test functionality.
    Other than that seems like a great addition of 2 rounds for virtually no added footprint to your mag. The baseplate design is also nice with 2 ledges on the side to be able to effectively feel and grab mag on mag changes.

    A bit tough to install. A few band-aids later, works exactly as advertised. Tremendous product.

    Great love my pluss 2 Maggut kit

  7. Ian Cadwalader (verified owner)

    A little tough to install, but that’s just because the springs are so high grade. The first couple times you load the mags will be difficult, use a mag loader. They function flawlessly, and add two rounds as advertised. You’re an idiot if you don’t buy these kits.

  8. Anonymous (verified owner)

    Hold open works flawlessly, only about 200 rounds so far but no malfunctions yet. Very satisfied

  9. Anonymous (verified owner)

    Nothing else to say! Works perfectly, buy one for every magazine you have.
    Simple, buy MagGuts, you won’t be disappointed.

    I love these +2 mag products. I have every variety for the P365 and they all work great. Shipping is also very fast.

    Place the magazine gently in a vice to ease assembly.

    No issues so far. Easy to install and seems to be working great!!!!

    Good product, terrible timing. I’ve inquired and waited on this for over a year and you waited to release them after Sig already made them obsolete with 17rd mags of the same dimensions. You should be releasing +2 for the new 17rd mags, not these. It could understand if it was a niche gun, but it’s the most popular carry gun on the market. Yall are really missing out on the $$$.

  22. Eric Evans (verified owner)

    I’ve used the plus 2 on my 12rd mags for over a year without any issue so I expect the same from these. I’ll be taking them out to test this week. The one downside to these guts is the spring is VERY tight starting out so its somewhat troublesome installing them. That said once completely installed, with a loader, the rounds go in and no rattle is noticeable. Which has been an issue with stock SIG mags. All in all I’m happy so far with these guts.

  23. Paul (verified owner)

    Excellent upgrade and functions perfectly. 17rds in a P365XL is a nice cushion. Magguts…..offer discounts! Do that and I’ll upgrade every Sig mag I have! Also, when are we getting a 2rd upgrade for the P365 Macro??

  24. KEVIN WALTHER (verified owner)

    I have several mag extensions. Unfortunately, I was unable to install the P365 kits as easily as the others and had to send it to MagGuts to have them do the work. I’m sure once completed, it’ll work as designed.

  25. Anonymous (verified owner)

    They did such a good job on this project that I prefer to carry this setup over a factory macro in an xl frame. A++

  26. DAVID M. (verified owner)

    I have used many different Magguts products over the years . The conversion units works great once installed. The first installation is a little tough, but once the new spring has been installed and used, it’s no so hard to reinstall after cleaning. A vise or a third hand helps!

  27. Salvatore (verified owner)

    Amazing product! Just like the other two kits magguts makes for the Sig p365 this works flawlessly with no Fail to feed, eject or any other malfunctions. This like the other two only adds a ever slight addition in bottom length of base pad which is not noticeable if you’re not looking for that.

  28. Stephen R. (verified owner)

    I’ve put magguts in several sig p365 10 rd and 12 rd mags, and I must say the 15 rd mag was not easy. I almost gave up. The spring leafs can flip on end inside the housing. When that happens, the spring assembly gets out of shape and has to be straightened out before trying again. Finally went real slow and kept adjusting the pressure will compressing the spring to keep it straight. Loaded with 17 rds, no issues. Haven’t been to the range yet, but my other mags with magguts work flawless. Expect the same.

    Difficult to install spring but well worth it. Works well and increases capacity to 17+1.

    Information. Id like if you guys come with these available in another firearms as well. Thanks guy

  33. Lee H. (verified owner)

    Excellent, well designed product, small challenge to install but once done it works like a champ. This kit now converts my 15rd XL mag into equivalent x-macro 17 rd mag I can use on my P365XL.

  34. David G. (verified owner)

    Awesome product, just like everything else from MagGuts. And half the price of 17 round macro mags.

  35. Jerry Hunt (verified owner)

    I’ve bought magguts before they work really well never any issues. I thought shipping was slow but it was Christmas time. I was well pleased with service and product.

  36. Jesse Cunningham (verified owner)

    I have a Sig P365XL. Iv used MagGuts 2rd kits in my 15 (17rd) and 12rd (14rd) mags. All function flawlessly. I have not seen any malfunctions posted on the forums either. Made in USA.

  37. Anonymous (verified owner)

    Pleasantly surprised, the tension is consistent throughout loading. Excellent fit and finish compaired to OEM (no corners).

  38. Craig P. (verified owner)

    Great way to improve the number of rounds without spending the extra money buying a new magazine if/when magazines are available. Reliability and affordability makes this hard to beat. Bonus is that it doesn’t add much length to the magazine and looks great too.

  39. Thomas Leavitt (verified owner)

    i broke the spring off the follower while trying to assemble ,had good luck with the 12 round conversion

    I felt it was irresponsible of me to consider spending $850 + for the P365 Macro just to have 17 rounds. I don’t care for compensates. My P365 XL shoots just fine. So for $33 I can have MagGuts which accomplished the 17 round wish!! Great job guys.

  43. Kent K. (verified owner)

    One of the smartest upgrades in firearm magazine history in my opinion. Recommend to everyone!

  44. Bryan (verified owner)

    After getting the 12+2 conversion and it working flawlessly, I ordered the 15+2 as soon as they were available. I haven’t taken to the range, but expect them to work the same (otherwise I wouldn’t have ordered). Followed the installation instructions and these now allow the stock P365 mags to hold 17. 17 + 1 for my P365X is pretty amazing for such a small pistol.

  45. Doy E Noblitt (verified owner)

    So far everything from your company has worked great. P365 10 to 12s, 12s to 14, and now 15 to 17. Thx!!

  46. Antonio S. (verified owner)

    I wasn’t really expecting any problems with this product since I already have a few of their magazine upgrades . I had a bit of an issue with installation of 17 rd flat spring on first attempt, but emailed Magguts and received a really quick response. They emailed me link to installation video that was helpful. I installed it in about 5 minutes on second attempt. Just fired 200 rounds with 4 different kinds of ammo without one single issue . Will definitely purchase a few more !

  47. Jeff C. (verified owner)

    Great product. Add two more rounds without adding anything to the size.

    These are awesome. Every mag should have them.

  50. Michael G. (verified owner)

    Holds 17 rounds, the last round is a bit snug, but not as tight as the 15th round in the original 15 round magazine. After converting my first magazine, the other three went together easily. I am planning on converting my other 6 P365 magazines.

  51. Franklin (verified owner)

    Easy install. Ships fast. Ran other Magguts in my other mags and they have been flawless so far.

    Awful and doesn’t work. Bottom 1/3 of spring gets thinner leading to issues getting the spring to compress and sit/fold properly. Watched videos and followed instructions which did nothing to help.With a ridiculous return policy, not even worth the hassle of returning. Waste of money.

    A little difficult to install but good as always

  57. PAUL M. (verified owner)

    I have purchased several of these products with a thumbs up. This new offering not so much. The spring simply was too long and did not seat properly. I ended up bending it and trashing it.

  58. Charles R. (verified owner)

    The MagGuts +2 conversion for the P365XL 12 round magazine, does in fact allow two additional rounds in each 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.

    Why keep looking for a sold out macro mag, this one works even better.

  60. Jose C. (verified owner)

    before with the original spring it was impossible to load the 15 rounds, now with the magguts conversion I can load 15 rounds but not 17.

  61. Robert Calhoun (verified owner)

    This work great so far. I haven’t had a chance to going shooting yet. Easy to in stall once I got it started. Will be buying some more.

  62. JAMES QUROLLO (verified owner)

    Does what it says. The physical act of installing the new guts to the 15-round Sig P365X magazine is fairly difficult though and should be done very carefully to avoid hand injury.

  63. Rick A. (verified owner)

    works good easy to install

  64. David Morales (verified owner)

    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!!!

  65. Kertis P. (verified owner)

    This is the best way to get a 17-round capacity for your P365XL. Shortly after I installed these, I got ahold of a Sig 17-round magazine for the P365XL Macro. Even though the Sig magazine comes with adapters to allow its use with the P365XL, there really is no comparison as far as fit and utility. The MagGuts +2 kit is hands-down better. Incidentally, I have the MagGuts +2 kits for both the 10-round magazines for the P365 and the 12-round magazines for the P365XL. Both of those work perfectly, which is why I purchased the +2 kit to turn the Sig 15-round magazine into a 17-round magazine. If they had the ability to upload a photo, I would show you the difference between the two 17-round options.

  66. Anonymous (verified owner)

    Adds the +2 like advertised and I love it cause it saved me some
    Money at the time. Haven’t shot it yet unfortunately, but lol forward to it and if it’s like the product for the 12 rd magazine, it should work fine.

    Has worked well so far, no issues. Installation pretty easy. Does not add additional length to the magazine.

    Was a bit to get the spring in the magazine on this one for it was easy on the 12+ 2 version. But did find a way to get it done. The warning of the edges being sharp are correct but even with that I found these to be excellent and function without any bit of issue. I highly recommend them for the Sig 365XL pistol and plan on getting some more as some as I can find the magazines!

  71. Tehran L. (verified owner)

    I struggled to keep the spring straight but once I got it it runs like butter .

  72. Chad D. (verified owner)

    Works perfectly fine, 1 thing I think they got rite is the fact that the base plate and the grip extension lock into each other, they are 2 separate pieces. This way the grip extension doesn’t slide everywhere and you don’t need 2 different base pads like sig made us use.

  76. John F. (verified owner)

    Great products worked well after installation, lube, & a few mags run through! Would buy again, but hope it’ll be less expensive next time.

    These are great. So far I’ve bought four and plan on buying two more.
