XTech Tactical MTX 365 +0 Magazine Grip Extension for Sig P365 9mm Extender
The ultimate comfort and control upgrade for your Sig Sauer P365 9mm pistol – the MTX 365 Plus 0 SIG P365 standard frame extension! Transform your standard P365 frame into the extended grip length improved over even the P365X/XL without compromising style or functionality by swapping the magazine. Made in the USA and California compliant (view all California compliant magazines), this innovative and patented grip extension is 100% reliable and designed to give you total control and improved grip on your firearm.
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!
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.
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!
The SIG P365 Grip Extension is compatible with factory 10-round 9mm magazines for the standard P365 9mm frame.
Our 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.
The SIG P365 Grip 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.
