Keeping set screws still...

[NJPaint]

I have an evil omen as a back up... It has a single set screw in the trigger for adjustments. the problem is that once I start fanning or walking the trigger (or just excessive use... the screw starts moving and the trigger length gets longer and longer. How can I make the set screw stay in place?

Put a drop of blue loc-tite on the screw then set it to where you like it and let it sit for a while.

yea either loc-tite or tephlon tape will work
any thing that puts resistance on the screw when its screwed in
