I just installed TFOs on my P229/.40 a couple of weeks ago--yesterday I noticed the set screw on the rear sight had worked itself loose enough to cover the front sight post. Anyone else have this problem?--I never heard of it happening before.
I reset it with a small Allen wrench, but have concerns it will happen again...thoughts? I was thinking about some Loc-tite (blue)...

Red lock tite works better with heat. Although , it takes some heat to remove a lock tited screw too. No knowledge of the sights themselves.

Yep, once you get the rear sight dialed in for your chosen load just remove the set screw, apply loctite to the threads and then reinsert and tighten it down. To remove, a soldering iron on the screw head for a few seconds should loosen the loctite.

Why would they have a set screw if it's a very tight friction fit??

Novak's low mount sights are set up the same way. While I'd say it's probably rare, recoil from hot loads might be able to shift the sights ... at least that's the only thing I've ever been able to figure out.

In my experience, if a dovetail is cut correctly, a set screw is an extraneous gimmick.
When you’re wounded and left on Afghanistan’s plains,
And the women come out to cut up what remains,
Just roll to your rifle and blow out your brains,
And go to your God like a soldier.

Since I needed a sight pusher to install the TFO's on my Sig, I haven't messed with the set screw.

Me too--I thought I was going to break it with the dovetail cut tight!...despite experience in setting sights in the past.Originally Posted by AutoFan
Thanks for your advice, guys...
I agree that the Loc~Tite red is better than the Loc~Tite blue.
And as per above it's still possible to remove a screw that has been set with red if you need to get it out.
Loc~Tite Stud & Bearing Mount is the real Kick Butt Loc~Tite and that is amazing stuff but, it's overkill for an average set screw.
Years ago I set a plunger tube onto an aftermarket frame with just Stud & Bearing Mount.
That was on my one junker "spare parts" Colt - I used the Loc~Tite without staking the plunger tube on - and it's still solidly on there.
It has survived probably slightly less than 5,000 rounds without ever coming loose.
It's important to clean and degrease the metal first for best results.
I'm sort of a Loc~Tite aficionado because my Wife's Co. supplies one of the key "ingredients" for Loc~Tite.

Well then, where can I find the purple loct-tite?
