I purchased 3 of these extensions. I use them for my S&W MP9 and in USPSA matches. Was able to bump up from 17 to 22 rounds. The extensions are very light and I’ve zero feeding problems with the new springs. In stall took only a few minutes. Grab you some!!
These things are awesome. Use them for my USPSA matches. Installed in a bout a minute with the new springs included. Even though they are metal, they are light weight. I’ve ran around 300 rounds through them with no feeding issues. Well priced to be attractive. Don’t hesitate, buy them.
I was worried about the belt not having a buckle to keep it closed and secure. The Velcro is very strong and secures the inner and outer belt together with no issues holster attached and secured perfectly.
Purchased for use on my S&W MP9 m2.0 with no optics cut. The fit is tight and a little blue loctite for safety. I’ve only shot 250 rounds since I stall, but no movement. I used the Vortex Viper RD with this mount. Ordered on Sunday night and was in my hands on Wednesday.
First 200 rounds without issue. Straight from packaging to install. Ran a patch through it to make sure it was clean. Fit was same as the stock barrel from S&W. Very happy!
