I have a series 80 mark 4 colt 1911. It has been a great gun but I just got back from the range and as I was cleaning it I noticed that the rear sight was lose. Not sloppy but I could click it back and forth about a 64th or less before it locked up then I could click it back. I don't even know if it moved enough make a difference at 25 yds. I am worried it will get looser over time. There is not hex set screw or peen mark to lock it up. How do you go about tightening up a rear dove tail sight?

had that issue with my springfield 1911-a1 had a gunsmith peen it in place. my a1 had marks on the slide and a notch to align with so i could tell the smith where to position the sight for windage.

It's a simple matter for your gunsmith to peen it in place. Inexpensive and painless too. PM me or post if you want to do it yourself and I'll walk you through it.

One other thing that could be done is a novak two dot rear sight that has the hex set screw. If I can't get the original sight secure this could be an option.

What about red lock tight? could a few drops of that fix the problem?

Replacement sights could be a good option. Inexpensive upgrade.

Great time for the upgrade
Mine came from Fusion a bit oversized (for my RIA) so i had a really tight fit after a few strokes of the file -

I used red locktite. I put it one let it set for about 30 sec. then removed the excess. The idea was to not let is soak in too much. I may want to change the sights down the road. The gun shot a bit low and to the right so I had to hold a bit high and to the right. I moved the sight as far as it would go to the left to help correct it. It was only about 1/32 at the most. If I have any trouble with it I will just remove it and get the novak sights.
