What color loctite for Glock front sight

[SPDGG]

I use Red, never an issue with the front sight coming loose or taking off a sight.

242 (blue) here.

I must be the only one who didn’t use thread locker on several of my front night sights.
All have remained fastened but this thread has me leaning toward reinstalling them with locker.

I've reinstalled one or more front sights at nearly every class I've been to for many years.

Usually more important that the type or color of loctite is prep. I come from an Aerospace background so I solvent clean and apply adhesives they way we did at Boeing. It may be overkill by I've never had one come loose, nor have I had a difficult getting one off (unless someone had it cross threaded). Plus as stated I glue the blade to the slide in addition to the threads and screw, basically trying to make the sight become a part of the slide and transfer the load.

I've had a lot of people bring me Glocks at work where the front is loose, it's clear there was no cleaning and just a dot on the screw, if that.

My cleaning process is to used a alcohol soaked q-tip followed by a dry one on each of the surfaces of the slide, the screw and even inside the front sight threads. It's important to follow up with the dry one immediately to pick up and debris that's "floating" in the solvent before it dries. This keeps it from just settling back on the surface you are trying to clean.

If you properly clean and apply the product as per instructions, Blue 242 works great. I've been using it for years and never had a sight come loose.

Red Loctite has worked well for me. No problems after a couple years and many rounds.

Edit: Make sure your degrease the area with alcohol first.

I like to use the low strength pink. I make sure the threads are clean. I have yet to have on come loose.

I have used blue in a pinch also.
