is it a good odea to use Blue loctite on grip screws?

I've never needed it.

Some use blue LOCTITE, some use clear nail polish, some use nothing at all.

Personally, I'd rather lose a grip screw than over tighten one and strip out the frame (on a SIG).

On a KAHR MK9 pistol, I finally resorted to blue LOCTITE because the pesky grip screws were very short, very fine threaded and were always loose.

If this is your choice, just snug them tight then a apply a small dab.

I do on my 229 DAK with factory screw I dont need them on my others with after market ones I use a very very small amount though

LOCTITE purple

just got done with my armouer class and he told us to use nail polish. Its easy it breaks away when you remove the screws.

Ah but nail polish doesn't hold as well either. As little blue locktite as I can get on the threads is what I use though always manage to spill so much, damned stuff. I may try the purple though

If the screws tend to back out then I use just a little on the threads of the screw and let it fully dry before putting it back in. It is easier to remove them later and they don't walk out again either.

clear nail polish (cheap CVS on sale) works very well for me on all of my grip screws

I seem to need it on just about every Sig I have.

So, do you allow the nail polish to dry before re-installing the screw?

No, put the screw in wet. The purpose is to allow the nail polish to bind with the male and female thread parts, tying the screws to the gun.

Loctite 222MS (Purple) is meant for smaller machine screws (MS), which is what the grip screws would be classified as. They will hold adequately but will be easier to remove than with the blue.

Another option is "camel snot" which is what we used to call 3M automotive gasket adhesive. It's yellow, product #8001.

If you're a car nut as I am, it might already be in your shop. Apply just a dab, allow it to dry or apply wet. It doesn't take but a very minute amount as it's very sticky...

Twist the screws down until you hit resistance, then give it 1/4 turn more.

This is what I was taught in my armorer's schools and it's worked for years on my agency's pistols. Haven't stripped threads or lost a screw yet.

I like snug,and a drop of blue loc-tite,it is the most secure /easily removable method,with the least risk of damaging fine threads in an aluminum frame.IMHO
