Need advice. The rear sight on this firearm is walking (drifting) to the right under recoil. Point of aim moves about 10" @ 10 yards in 30 rounds fired. Sight does not have any kind of set screw. Anyone know of a fix? :confused:

You could try to find a replacement with a set screw.
You could raise some teeth on the bottom of the sight with a center punch.
You could use some blue loctite and glue the sight in place.

All the above methods will work.

When putting dimples in to form raised metal, always try to work on the sight, not the slide.
A First Rule of gunsmithing is to work on the part that's easiest/cheapest to replace if something goes wrong.

Remember, the idea is to raise metal not just put punch marks on.
Use a slightly dull center punch and hold the punch at various angles to raise metal.

When using a Loctite, first degrease the sight and slide.
If they can't be easily removed, use some denatured or 91% alcohol.
Put a big drop of the alcohol around one side of the sight, put your mouth over the area and blow the solvent through.
Repeat a few times, then use a hair dryer to warm the area to dry it.
(Sounds nasty, but it works. Use a hair dryer, NOT a torch or heat gun).

After drying, put a good drop of Loctite on one side and blow it through the dovetail area.
Rinse mouth.
Let it cure 24 hours, wipe off the excess and apply some lube to prevent rust.

If the sight is really loose in the dovetail and raising a few center punches on the bottom of the sight doesn't help much, you might consider putting a couple of punch dimples on the bottom of the sight quite near the edge of the dovetail. This will swage metal outward since the metal is thinner near the edge, effectively "widening" the sight at the base.

It doesn't take as much as you might think -- if done correctly, the metal will barely appear rippled. Once you get a tight fit, Loctite will help keep it from moving around.
