Tuning M3 trigger problem.

Installed 35 slug power kit on 30 cal. I decided to adjust the trigger. I accidentally loosened the silver screw that ernest say not to. Now it seems to loosened on its own . I took the trigger off. My problem is the safety doesn't work after a while I have it sitting with locktite. Has any one had this issue. I hope it just needs locktite. Apologies for hating on other people's guns. Everyone entitled to like their gun.
