View Full Version : Loctite

August 29, 2005, 02:07 PM
First off, if this is the wrong section, my apologies.

Anyway, the post.

Today I had night sights put on my Glock. The store I bought it from also did an installation.

He mentioned putting some loctite on the front sight, and I admit, I was unsure. I am a poor gunsmith (I can field strip and clean, but that is about it.) so I said nothing.

He advised me not to shoot it for 24 hours, my question is should he have needed loctite to install my Meprolights, and even if he shouldn't is it going to be an issue?

Thanks for any help.

Locktite is required on the front sight.It's mounted with a very small screw. ;)

Sounds like you did the right thing by having the other guy install those Meps! ;)

Loctite is wonderful stuff. It will "cure" in the absence of air. By putting it on the threads of the screw, it will harden under the screw head. It does not take 24 hours to "cure". It should be shootable within 1-2 hours. (If you want to speed up the "curing" process, take a propane torch and put a little heat in the screw (5 seconds should be plenty).

If you ever wanted to remove the screw (and you didn't use the removabe loctite) just heat it up with the torch and it will break the loctite. If you have any doubts or questions about heating loctite, ask someone at a local machine shop.

Using a propane torch on sight always worries me. What I do instead is really heat up a screwdriver or allen wrench and use transfer heat to do the job. Of course after heating up the tool, it takes the temper out of it so i don't use my very best stuff for that job.

I've used red (271) Loctite for instaling front sights on Glocks for years. Have had to remove a few; never had to apply heat to remove. If I did apply heat, seems to me that a soldering iron would be better than a torch.

The directions that come with both the sights and Loctite suggest that the Loctite should cure for 24 hrs.
