I screwed down the Vortex Venom pretty tight and used LocTite. I'm actually more worried about when or if I ever want to take it off. lolI went to shoot mine for the first time and after 6-7 shots the trigicon flew off. Couldn’t find the screws so that was that. I still need to get the correct screws for it and try again. I can’t remember if I had tightened the screws to the proper specs or not so it was most likely my fault. I had other 10s with me so I shot them and just never got back to the G pistol.
I made sure the screw on top that holds the battery in is screwed down tightly as well. I've seen videos of that screw flying off.
