What is the XTECH TACTICAL - MTX Mag Extender 12-Rd to 15-Rd for 9mm Luger P365 Black?
The ultimate upgrade for your Sig Sauer P365 pistol – the MTX 365 Plus 3-Round SIG P365 12 rd to 15 rd Mag Extension! Transform your standard P365 frame into an extended grip with 15 rd capacity without compromising style or functionality by swapping the magazine. Made in the USA, this innovative and patented magazine extension is 100% reliable and designed to give you total control and improved grip on your firearm.

The SIG P365 Mag Extension is compatible with factory 12-round magazines for the standard P365 frame. Please note this only works with Sig P365 12 round magazines and standard frames. The unique design enables the extender to work on the Sig mag body with inward-facing tabs where other extenders cannot be used. This also allows for seamless integration with the P365 platform without compromising the overall aesthetics of your firearm.

One of the main features of the SIG P365 Mag Extension is the custom-engineered spring, which guarantees unmatched reliability and ensures last-round bolt hold open. The MTX 365 12+3 Round Magazine Extender also comes with a detailed installation video QR code to guide you through the simple process of adding this essential P365 upgrade to your firearm.

Furthermore, the SIG P365 Mag Extension provides the perfect pinky extension for tactile feel and control, allowing you to maintain accuracy and precision while shooting. In addition, the grip extension dramatically improves grip and control without having to go for the XL frame, giving you the confidence to manage your firearm in any situation successfully.

Lauded as one of the best P365 upgrades available on the market today, the MTX 365 12+3 Round Magazine Extender with Spring for P365 takes your shooting experience to a whole new level. With its innovative, patented design, US 11,408,697 B2 and US 11,168,954 B1, and unparalleled reliability, this superior accessory is a must-have for any Sig Sauer P365 owner looking to enhance their firearm’s performance and take their shooting skills to new heights.

Been looking forever!
I’ve been looking for 15 round P365 mags forever. This magazine ( +3 ). extension is easy to install, turning 12 round mags into 15 round mags. I’ve put a box of ammo through each one and they work flawlessly.

Hits rock bottom at 14 rounds. Mine was purchased fully assembled with 12 magazine from the XTECH website. This 12+3 magazine assembly is much more bulky than the 10+3 and you only get 1 more round into the unwieldily large magazine.bulky an
Follower hits bottom at 14 rounds. Only 1 more round than the 10+3 mag, which is the perfect length.

Waste of time should've bought the 12 round clip from Sig
This is an awkward conversion that doesn't hold 13 rounds very well. I was able to load 13 once then only 12 and it was VERY difficult.

Pure junk
I tried both the 13 rd extender and the 15 rd extender which I purchased from Brownells. The 13 rd extenders worked fine in original 10 rd magazines over and over. The 15 rd extender didn't work at all. I had so many failures to feed that I am going to return it to Brownells for a refund. The magazine spring in the kits appears to be the same for both kits and it's way to light for the 15 rd kit. Buy the 13 but avoid the 15.
