Rear sight moves?

[SavageSig]

I've got a Springfield 1911 with Novak sights. The rear sight has a set screw that's supposed to keep it from moving around. However, after a few mags, the set screw will work itself loose and a gentle tap will easily throw my rear sight off alignment. What are some things I can look at to stop this?

Loctite?

Teflon tape?

Get a new rear sight?

Red loctite. The red is really strong.

Red loctite. The red is really strong.

+1 use this on all my scope rings.

red loctite, as said before.

Thanks for the help guys. I was thinking blue loc-tite, but I guess red is required to stand up to the .45.

No, No, use blue. I think the red is permanant.

They also make a locktite just for guns. I believe it is green.

+1 Use red only if you're sure you never want to move it again. Blue is what most people use for scope rings.

Start with the blue. If it doesn't work you can always try something stronger.

Blue might work just fine. But the slide takes all the beating and I have had no trouble breaking the red free when I needed to do so. FWIW.

I used purple on my .40 and the sight is still in place. It's weaker than blue (as I recall).
