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.

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.

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!

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.

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

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

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

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.

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.

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.
