Hey guys, recently purchased a 995 in an ATI stock. With my Trigger Plate's rivets - one of them is missing (broken completely off), and the plate itself is not exactly planed/level. (Its a bit bent) 1.) Is the trigger plate supposed to be permanently riveted to the receiver? (AKA never, ever removed) 2.) What fixes can keep the Trigger Plate in place to ensure the Sear Cam (Part 31) and Trigger Assembly (Part 30) don't incorrectly move around. (I am experiencing slippage of parts) Thanks, and I apologize for no photos!
