Securing front sight

[Forester]

Looking for input on securing front sight.
I'm shooting a shadow systems MR920. They use a Glock pattern front sight.
The problem I have is that during high round count (300+) rapid fire training days the front sight loosens up.
Multiple times I have taken it apart, cleaned it and replaced using "red" thread locker. Continuing to perform the same repair doesn't sound like the best solution.
I appreciate any thoughts or suggestions.

Thank you

Have you contacted Shadow Systems to see what they might have to say?

Not yet. But I will send an email

Did you thoroughly degrease everything prior to using the Loctite? I use blue and it holds, I only use red on gas block set screws, it should be serious overkill in a front sight.

This ^^^
I wouldn't use red on that tiny screw.
If red isn't holding you're doing something wrong like not de-greasing.

And keep in mind that if you can get red to work properly and you ever want to change that sight out, you'll probably have to break the screw.

I checked and I was mistaken on the thread locker. I had used green. I've been using isopropyl alcohol to clean. Is there a better solution to my degreasing? Sounds like that may be my issue.

Appreciate the good info.

Thanks

Rubbing alcohol should be fine.
Take an old toothbrush and scrub the threads.
I use Loctite 242 Blue for the Glock front sight.

I think your Permatex green might be a lower strength.

Dave Dawson of Dawson Precision floods the sight pocket on the top of the slide with Loctite.
I have never tried that. Just the threads for me.

Copy….I'll get Loctite. The permatex has not been working.
I'll brush it and try that

Correct, green is between blue and purple
