Used on my p322 - Evolution Gun Works Vortex Viper/Venom fits Burris FastFire and Docter Sight Mount For Sig P365 Optics Ready

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.
