Marlin 925 trigger group-receiver screw loosening problem

[Guest Jo7hs2]

I'm curious to know if anyone else has had this problem and has a solution. I got a Marlin 925 (bolt-action .22lr) for practice purposes, and in generally I am very satisfied with it. The only issue is that over the course of three weekends at the range, with probably 500 rounds run through it, the screw that holds the trigger group came loose. At first there was wiggle in the safety when operating the trigger. Then, the trigger required four or five times more force to operate. Finally, it started giving weak strikes and I went home, rather than accumulate a pile of struck but unfired rounds.

When I got home, I researched the problem and found out it has happened to other people. No biggie to fix, just detach the stock and tighten the screw, problem solved. One person said he put a lock washer on it. There is no washer by default, as far as I can tell. It was loose enough I expect it will reoccur.

Had this happen? Ideas?

Blue "thread locker" locktite. You can still take it apart if you need to.

I think I will try some 243 blue, thanks for the suggestion.
