  1. Question


    Might be a dumb question but would this fit on a Sig P320? I think that would look baddass and the slide serrations are almost the same angle. Just wondering if anyone’s tried it before. Thanks!

      This Comp Weight will not fit the Sig P320. It was specifically designed for the VP9 and VP40.
