mainspring aka strain screw adjustment?

[Thaddeus Beauregard]

Has anyone else experienced screws that have backed out? Is there a good fix for this that won't mess up the gun?

Yes, snug it down completely. If it's tight, you shouldn't ever have it back out again. The bottom of the screw head needs to make firm contact with the bottom of the counterbore.

Thanks, that's a load off
