This is my first venture into the world of rigidized miniature reticle optics. I got impatient and installed a brand new vortex Viper on a 9 mm pistol but noticed when I really screw it down to the plate tight it somehow makes the battery lose contact. About 1/8 of a turn to loosen the two screws up and the red dot comes back on. The manual says nothing about a torque ratio so it leaves me wondering. It seems I would want the screws as tight as possible, without overtorquing, for proper installation. Has anyone ever heard of this dilemma?
