Help with Novack Sights on Combat Commander

[FlameRed]

This is really for my brother-in-law. We both have brand new Colt Combat Commanders that have the low rise Novack 3 dot sites. On his gun, the rear site moves quite a bit after normal use, even though the set screw is torqued tight and to put the site back in the middle, I have to beat on it with a hammer pretty hard to move it with the set screw completely out!

Mine has not moved, yet.

I don't understand how recoil can cause it to move with the set screw in tight, and the thing won't budge unless I hit it pretty hard with a hammer when the set screw is completely out?

I have heard that the trick to fix it is to 'dimple' the slide where the set screw hits? And Locktite the set screw of course.

Degrease the whole thing, sight it in, then loctite the sight in the dovetail.
