Absolute game changer. I took it out to the range this morning and the stability I’m getting now is night and day. Plus, that threaded tip is just begging for a suppressor. Shipping was surprisingly fast, too!

I’ve seen the videos, but holding it in person is a different story. It turns a standard sidearm into something much more capable without adding a ton of bulk. It’s snappy, responsive, and just plain fun to run drills with.

Just got mine in the mail and the first thing I noticed was the build quality. It’s rock solid. I was worried it might feel “plasticky,” but it’s dense and premium. Major props to the fulfillment team for getting this to my door three days earlier than expected!

The balance is perfect, especially with the extra length on the barrel. It cycles like a dream and looks like something straight out of a sci-fi flick. 10/10, would buy again in a heartbeat.
