I have the sight mounted to the rear of the breach, if that makes any difference. The glass is directly above the front of the bolt release. Please post up a picture, it may help. - Were you able to sight in with the sights, before you added the Venom? - Do you have a friend that can loan you the rail off...Jul 20, 2017 · Just wanted to share my favorite sidearm. It's a Grand Power X-Calibur with a Vortex Venom red dot. The Grand Power rotary locking mechanism is amazing and makes this a very soft shooting pistol. Accuracy is phenomenal. It took a while to find the right mount, but EGW had one for the Gold Cup that fit this pistol perfectly.
