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!
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.

I have a CA compliant P365 with mag disconnect. Nobody makes XL grip modules that are compatible with the mag disco FCU. This extension gives you the “XL” grip for $23 and your mag is still 10rd. Fits great, easy to assemble, excellent option!

I’ve tried two other grips, the extension that came with the gun. Okay but too short. A second from another company, ever time I fired the gun the extension pinched my hand. This new magazine from xtech is perfect it fits my hand perfectly without the pinching effect when I fire the gun. The MTX 365+0 Grip Extension P365 9mm EXCELLENT PRODUCT 100%

I have a MA compliant P365 so with max of 10 rounds this grip is perfect. Much more comfortable feeling when shooting.

I recently purchased a CA compliant P365 and wanted to find a longer grip co I bought 2 pairs of the MTX365+0 Grip extensions and added them to my 10 round magazines, what a difference, so much more comfortable shooting the gun. Excellent Product 100% sold.

Sig p365 CA compliant
Instead of buying a grip module and then modifying to fit magazine disconnect , I chose this route .
Inexpensive , easy install , feels great in hand and I’m still compliant with my county’s requirements for CCW purposes.
Will buy more and recommend .

Excellent.
Bought the 365 for pocket carry. Mag extension is excellent for IWB carry. Need to pocket carry simply switch mags. Excellent product. Very easy to install. Mag extension gives flexibility that a new larger grip does not.

Product is great and very innovative. It utilizes the existing oem magazine not only adding to the capacity, but dramatically improving the grip. I highly recommend purchasing this product.

California Compliant P365. These are perfect for my hand size and does not require me to modify anything on the pistol itself. I had to watch the instruction video a few times before it made sense how to install. Take you time, do not rush. I will order more when I get more magazines.

Stumbled upon this through Reddit of all places. These extensions make gripping the p365 way better! Installing takes minutes.
Highly recommend.

For $15 my CA compliant P365 feels very similar to a CA compliant P365 X-Macro which costs about $330 more.

If you’re looking to get more contact on the grip. These extensions make all the difference.

I am extremely happy with these extenders. It makes holding onto the P365CA alot easier. This is an excellent option instead of buying a new chassis, since we can’t purchase the P365X in California.

The instructions for the instal was very confusing and was difficult to install. But, once installed I have zero complaints. The extender is very well built and feels amazing in my hands. The groove for the pinky is also game changer. Thank you!

The order was shipped and delivered quickly in just 3 days. Took time to attach the extension to my magazines, but feels very good and more spacious now, giving my pinky finger more space and a better grip whilst complying with CA regulations.

I have the MA compliant Sig 365. Watched the install video on the XTEC site. Installs easy and feels great in my hand. Can’t wait to try it at the range.
