How'd This happen?

The rear sight on my TH9c had to be adjusted when I first got it. I moved it to the right, all was well. This week I've been shooting it and figured out it's shooting left again. Apparently the sight had migrated back to the left despite the set screw on the sight still being quite tight. Hmm. Well, I re-set it and drowned it in blue loctite this time. It's shooting straight again. We'll see what happens.

Single set screws aren't usually absolute unless there's a detent/dimple for it to seat into. The receiver scope mount for my Enfield has three or four set screws and even though I've had them all tight enough to be on the verge of stripping, it still moves after 5-10 rounds.

Well, if the loctite don't keep it in place, maybe superglue will.

I dont think it the threads backing out, it's the screw not being able to bite the slide.
I'd mark it where it shoots good, and a little super glue might be in order.

Check your gun safe for this guy.

Call Taurus and get a label on their dime...the set screw should have a serrated cup end where it contacts the bottom of the dovetail.

Well, I really don't wanna trust Taurus to get my gun back anytime this century over something I can likely fix myself.

You have a liberal sight. Always moving to the left.

Well my suggestion is to get in touch with Jake!
you know his first cousin Clarence works at Taurus and is in the sight installation and zero department and can likely add some Professional advice to you!
Now be sure and mention Clarence, as he is the cross eyed one, his brother Terrance works in factory lubrication of shipped weapons!
