I have a Mark IV Hunter and the front fibre optic sight has a very small screw
and every time I shoot even 30 rounds the front sight gets loose and when I shoot
even more the sight is ready to fall off. Ive used loctite blue and it still comes loose.
Help, what can I do????????

You might try a real small rubber o-ring on the screw. S&W Victory had trouble with barrel screw coming loose. An o-ring or a star washer supposedly worked for the problem.

Try some purple Loctite.

I've completely given up on the factory slotted screws. Those screws include a blue thread locker that just doesn't seem to do the job. So, I find these "custom" torx screws work out much better.
