View Full Version : The sight keeps coming loose

March 19, 2009, 10:34 AM
I have a Taurus .22 mag pistol with a rear sight that can be adjusted for windage. But, after so many rounds of firing, the sight comes loose.

I'm afraid to over-tighten the little set screw because I don't want to strip the threads. Any suggestions?

Here is a picture:

Loctite it.

Will Loctite allow me to keep adjusting the sight until it's right and still do the job? I can't loosen the screw to use the Loctite once the gun is sighted in because the sight will easily slip out of place.

You can peen the edges of the sight just a little bit where it fits into the dove tail. That will make a tighter fit and still allow it to be adjusted. Once it's sighted in use blue loctite on the screw. Use red loctite and you'll never get it back out without using heat.

use a punch to stake it in place

Not exactly sure what you mean by that.

use a punch to deform the metal slightly where the dovetail overlaps the rear sight. You can use a center punch, which will be most secure, but will leave a small punch mark. This will leave a small dimple that will force a small amount of metal from the dovetail into a small indentation on the sight. You can also use a round nose punch which will tighten the gap without leaving an indentation in the metal.

Ok -- got it. That sounds like it ought to keep it place after it's sighted in alright. In attempting that, however, it would be just my luck to knock it out of place.

If I'm going to scratch the gun, maybe I should simply scratch a mark to line up after it's sighted in, and then loctite it. Sometimes the decision is the tough part!

Blue loctite will allow you to still adjust the sight. The non hardening formulas allow you to loosen and retighten the screws a coupe of times before needing another application of a drop or 2.
There is a blue loctite that is a stick (like lipstick) that you can use.

Before doing anything else, tighten the set screw. That's what the set screw is for.

A/C Guy --

Thanks for the insight on the blue loctite -- that sounds like the way to go on this.
