Gen 5 Glock 17
Trijicon HD's (removed from a Gen 4 G-19)
After a few hundred rounds the rear sight progressively slides to the right. Right side of the sight will sight flush with the right side of the slide.
Sight history. Gun shop dude put them on my gen 4 and then on the gen 5. I watched him do it and there wasn't any forced movement either time. It went very smooth. He used a really nice sight pusher, I believe the one he had was Glock specific.
When I checked zero I needed to bump the rear sight no more than 2mm right and I used the ranges multigun sight pusher.
Shot the TPC handgun mastery course and than immediately a weekend long match (Hard as Hell). On the 2nd day I noticed my POI was way off and when I looked at the gun the rear sight moved. I used my friends sight pusher and moved it back to zero.
Probably but about 700 rounds through it since then and it has slipped all the way right again.
1. Can I lightly peen the slide and edge of the sight? What size punch and technique should I use?
2. Loc-Tite? If so - technique?
I plan on permanently keeping these sights on the gun.
3. Why did it move? Glock and Trijicon should be pretty solid.
I appreciate any advice.
