If your guy's sights do get loose, it's really an easy fix. That height adjustment screw comes all the way out and you'll see the set screw there. You may be able to just tighten it up and it may be fine? You may never even have it loosen up!? But if you do, I suggest you do as I did. Maybe get a new set screw (Possibly found at a gun smith store? If not, A local hobby store for Remote Control cars and stuff will have one of those set screws) and just mark on the slide where the screw would sit if the sight is centered, and just buzz out a bit of material for the set screw to center itself into and then loctite everything.
I wish you guys luck!![]()
thanks for the tip
