It fits perfectly and its really light. Definitely worth the price!
Most Recent Reviews Used on my P322 by JJ, April 28, 2024
Worked great for my P322 and Vortex red dot. Only issue was that I had to machine off the nub at the bottom which wasn’t a big deal. I machined the entire face down so the optic sits lower on the gun. Worked great.
