All components of the magazine except the steel magazine body are manufactured by XTech Tactical

Unlike the now discontinued Sig Sauer P365 15rd magazine, our combo give you a much improved grip and control over the pistol by filling our the back of the magazine and therefore your grip.

Our engineered spring with our injection molded sleeve and MTX extension give you a package you can count on regardless of your use. Our extension uses both of our issued utility patents to extend a magazine with inward facing base plate rails and eliminate any catch point when the follower transfers from the extension to the magazine body.

This set up with the standard Sig 365 is ideal for back up magazines or if you live in Colorado which limits to 15rd magazines.

Compatible with the standard P365 grip module, Wilson Combat standard grip module for the Sig P365, and many other standard sized modules

-Will not fit the P365 X or the XL or any version of the MACRO

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.

-The ideal ergonomics (shape) of the MTX gives you a natural high grip on the pistol. Compared to the factory 12rd magazine which brings your palm down due to its angle pushing your pinky forward. Also, we have never met a customer that doesn’t prefer our MTX installed with the standard module over the X or XL grip module. That paired with the ability to shrink down with a magazine swap make this a no-brainer!

-Easy adaptability: we live in Arizona where the weather for half the year gets super warm. So there are times where we struggle to conceal our P365. With the standard module and MTX set up, if you need a smaller package size, just swap your magazine to a factory flush fit magazine.

-Flawless feeding: our newest utility patent for magazine extensions do make us the ONLY P365 magazine extension for 10rd and 12rd magazines. But you are in luck as our first patent allows us to guarantee flawless feeding. We have thousands of happy customers with ZERO known feeding issues. This is also in part to our extreme testing protocol. We do all we can to ensure our products are ready for release before we launch them. This product took over 12 months longer than expected. But that’s our commitment to you!

-100% Custom Engineered Components: this was not the initial plan, but we ended up developing every single element of the magazine (outside of the magazine) body from scratch. The spring is precision engineered from 17-7 stainless steel to match the force profile of the factory spring. (This is a feature of all our MTX products)

-Ideal length for best grip: the 13rd Extended Magazine is the best balance of length and round count available. The grip gives you complete support and a better natural point of aim vs the factory options.

Please note this only works with P365 9mm standard frames

Everyone celebrated the P365 hitting the roster in California, until Californians realized but the rest of us already knew, it’s too dang small for most applications! Fear not, we have the best grip extension here for you!

Perhaps the best parts though are even more exciting than you first realized:

#1. We have our Free State Adaptor +3 kit. We were there for Californians during the infamous “Freedom Week” if it happens again or if/when you move you simply need our kit and you get 3 more rounds! It’s legal in all 50 states due to the magazine body design with the inward facing rails. If you remove the blocker in this kit, you get a non functional magazine and no more rounds. The only solution to add rounds here is the Free State Adaptor Kit we offer. It does not ship to restricted states. Let’s fight together for your rights and support GOA and other groups on the front lines!

#2. We give you a great value! We do not believe in taking advantage of folks in restricted states.

#3. The details: the texture, the ergonomics, the styling, we have you covered for all of the above! In fact we feel that our magazine extension look superior to the Sig extended options. This is the ultimate 10 round magazine base plate for the Sig Sauer P365 pistol.

#4. Our grip extension gives full support and the best ergonomics! We as a brand do not support the forward angled pinky extension approach from the 1990’s. The forward angle that Sig Sauer and others use brings the web of your hand down, and fights you from maintaining a high grip. The angled pinky extension approach also does not support the back of your hand. If you feel our product in hand, you will know you have the best solution in the market, period! Thousands of happy customers agree with us!
