I recently bought a new threaded barrel for my Sig Pro 2022.  When I clean the pistol I tighten the thread protector with a pair of padded pliers, but then when I go to the range it comes loose after a couple of magazines and I'm afraid I'm going to lose it. Stupid question time - am I SUPPOSED to take it off before shooting or is there something I can put on that will help it stay put but allow for it to break free when it comes time to clean it?

Well, I'd say Loctite, but that does come loose with heat, so...

A trick a fella taught me was to use Teflon tape as a thredlocker.  Works good, can take alot of heat (I used to solder joints with the parts already threaded together), and it comes right off when you unscrew it.

Experiment with lots of blue or a little red loctite.

Thanks guys!

I think I'll start with the Teflon tape and move to the adhesives as needed.

Honestly I put some heavy grease on the threads on mine and screw down the protector, It wont stop it 100% from getting loose but it gets way way less loose.  Some guys use a rubber O ring as well behind it to screw it down on.  Me, I will stick with my grease, it keeps it on there and not coming loose enough to fall off when shooting.

I used a rubber o-ring on my FNX-45T, worked like a charm and never moved.
