Rear sight pin wants to leave the gun! (Mark III 22/45)

I've had my Ruger MKIII 22/45 for several years now. Got it back when they were dirt cheap (and actually available) in CA. I have the model rigjt before they went to the removable grip panels, so I bought the rubber grip panels that were an aftermarket addition.

I love the gun, but it has one small problem - the pin in the rear sight, the one that allows the leaf to pivot from the rear sight base, always seems to drift out when I shoot it. It hasn't come completely loose yet, but I suppose it's just a matter of time. I don't want to drop some loctite on it, as I want to retain the functionality of the rear sight.

A very slight bend in it should do the trick.
Or only put lock-tight on one end.

22 magnum has it right. Next time it has drifted out about half way, tap it downward lightly, putting a slight bend in it, then drive it back in. That's the way the factory is supposed to install the pin, but it is a very common problem, so it apparently doesn't get done much. Don't use loctite.

Tiny bit of blue Loctite on one end works great! And you can remove it if needed.

I noticed this on my Mark I Target Model last time I had it at the range. Thanks for the tips to fix it. I probably would have put Loctite on it, but I like the idea of just bending the pin better. Just tap it in. Just give it a little tap. Just give it a little tappy tap taparoo.

Thanks all - I like the idea of putting a slight bend in the pin instead of loctite.

Little side story regarding loctite and this same gun: when I first got the gun, I wanted to make it as "Buck Rogers" as possible and so, in addition to putting those rubber grip panels on it, and swapping out the front sight with a green fiber optic, I decided to mount a Bushnell TRS-25 RDS on it. I dutifully attached the picatinny rail on the top, and made (unfortunately) liberal use of blue loctite to make sure the sight base wasn't going anywhere.

Well, tastes change, and I wanted to bring the pistol back to something approaching normal, so I took the red dot off and also the picatinny rail. Urghhhhh - LOTSSSSS of leftover residue on the top of the gun, and extremely stubborn to boot (as loctite was meant to be). For a good while, I just tolerated it, all while chipping away here and then with my thumbnail, since I didn't want to use any tools that might Mar the finish.

Just recently I managed to scrape off the last of the offending residue, and the gun looks a lot better.

So - I won't be using loctite on this baby again...
