Loose front sight insert - question

Jay,

The best way to tighten the dovetail, is to take out the sight.

Find a piece of steel bar stock about 5/8" diameter.

Clamp the barrel firmly in a padded vise.

Lay the bar stock across the top of the dovetail. Be sure that is parallel with the edges of the dovetail and squarely and firmly touching the edges.

Now tap it very lightly with a small hammer. Try the sight for fit.

If it's still loose? Repeat the procedure as needed until the sight resists and has to be drifted into the dovetail.

This method, if done correctly, will upset the dovetail edges without showing signs of peening.
