Single Seven Sight ??

[flyguy958]

Bought a new single seven and the front sight slides through the dovetail almost easily. Had the same problem with a SP101 in 22LR but it had other problems so I sent it back for repair.

What is the easiest way to to secure the front sight? Don't want to send the gun back for this issue.

As a note, the SP101 was returned within 7 days will all problems solved. Great service, just wish QC had caught the problems before shipping.

I'm a bit confused here: the front sight on my S7 is not dovetailed, nor have I seen any that are. I thought they were secured either in a brazed base or with a screw like the Single Six.

I believe the standard accepted practice for securing a loose dovetail is to rough up or peen the slopes a bit toward the middle and use something like red Loctite to make it permanent.

The traditional military armorer's fix for a loose dovetail:

Using a steel center punch put 2 to 3 "dimples" in the bottom of the female dovetail slot to raise the metal with the dimples getting progressively deeper as you move from right to left. This assumes that the sight is driven in from right to left with the gun pointing forward.

You are correct, it's a SP101. Don't I seem like a dummy. Bought both a single seven and a SP 101 too close together.

I prefer to peen the top sharp edges of the dovetail to tighten. Dimpling the bottom of the dovetail will raise the front sight a bit but worse than that, the sight may be canted once installed.

If you use a center punch to raise dimples, do it on the bottom of the sight, not in the bottom of the guns female dovetail. I do like Hondo said by using a brass punch to just barly peen the edge of the barrels dovetail down. No need to over do it. It don't normaly need much.
