View Full Version : Dan Wesson rear sight issue

--------------------------------------------------------------------------------
I have a Dan Wesson 357 MAG revolver. I'm adjusting the rear sight.
Using the little hex-key, I have been able to adjust the rear sight to where it shoots dead-on (POA=POI) at 25 yards.

However, the rear blade with the notch now feels a little loose on the end of the 'rail' of the sight (the part that's screwed into the top of the frame).

The windage adjustment (forgive me if I'm not using the correct terminology) is a hex screw on the right hand side of the gun.
However, if I look on the left-hand side of the sight, it looks like the hex screw is threaded inside a second screw, which will take a small flathead screwdriver.
Should I be holding the external thread/screw while turning the hex on the other side? Will that not move my sight out of alignment again? Do I need some special tool for this?
The left hand side looks something like this:

-(o)-

With the - being a notch that runs through the top of the screw, () is the outline of the external/second screw and o is the end of the hex screw.

Edit: per the Dan Wesson page, the screws are the Windage screw (hex on the right) and the windage retainer screw (on the left).

I know this should be fairly easy to do, but at the same time I don't want to bugger up my gun or completely jack up my sight alignment, so I get to spend another afternoon (and 75 rounds) sighting it in all over again.

Sorry for the long thread. Any feedback is welcome at this point, even if you tell me to dump the sight and buy a new one (if so: which one?)

Thanks

I think I've figured it out in theory, but I'm no closer to fixing it.

The Windage Retainer Screw on the left locks over the Windage screw on the right. The problem is: it looks like I need some sort of 2-pronged screwdriver to tighten the windage retainer, while holding the hex windage screw in place on the other side.

Am I correct in this? Am I looking at dremeling a small screwdriver down the middle until it does the job?

The older Dan Wesson revolvers had rear sights that tended to wobble a little. The best solution is to do what the current Dan Wesson company has done, replace them with Millet rear sights.

It's normal for these sights to "wobble". They're mounted with a screw running through them and have to be in a slot that allows them to move back and forth easily. So you are always going to have some front to back movement of the blade. George

pvanosta,

Dan Wesson had a lot of problems with their rear sights in the 1980's.

Adjustments and repeatability were very poor. I replaced mine with Millet's, and never looked back.

Good Luck...
