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!

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.
