I’ve seen the heads of Glock sight screws shear off… maybe?Quote:
I don’t think it’s the screw for one reason.
The barrel in the slide will keep the screw from coming completely out. It will not keep the front sight from getting loose and it’s proximity to the barrel is why I use red Loctite on the front sight because it sits literally right above the barrel (I don’t have measurements - but I’d say less than 1/10th of an inch).
I had a front sight wobbling loosely once and couldn’t figure out what my problem was with shooting that day. The front sight was loose and moved when I bumped it. It’s probably my one legitimate gripe with Glocks - I think they should use the same dovetail for the front sight as they do the rear.
To take things further - on one of my Glock 34 Gen 5 the front sight had been installed with red loctite. When I went to change the sights to RDS height sights I figured let’s see if the screw would loosen without heat (again red Loctite requires heat to loosen). Sure enough it did - no lighter or warming up required again because of how close it is to the barrel on that end of the slide.
It has me contemplating green loctite. I’m interested to see how this goes!
