My K22 dates 1951, and someone messed up the slot in the yoke screw...Is it simply a "screw" in a new one,or is fitting required?. Guess I could file the head a bit and leave it alone, and put it back in... kind of looks funny, all other screws are fine. Part looks to be available.....

Yes, it has to be fitted - too long and it binds up the yoke barrel, too short and it doesn't retain the yoke. Dressing up the head sounds like a fine plan .

It needs to b fitted to prevent the yoke from binding. Newer guns (since the 80's) have a different system which uses a screw with a spring loaded plunger to eliminate the need for fitting. Not sure whether they'll work on older guns....

Fitting may not be needed, try it out and as murphydog stated if it binds on the yoke a few strokes with a file should ease it up.

Nope.. different size screw entirely.

Take your original screw and put it in a padded vise. Then, use a hammer to tap the raised edges down. Next, secure your variable speed portable drill in the vise with the chuck horizontal. You now have a poor man's lathe.

Chuck your screw in the drill but don't damage the threads. Turn on the drill and dress the head of the screw with a fine cut file. Polish the screw head with fine sandpaper or emory cloth. Degrease, then wipe the screw with cold blue until you get the color you like.

Several times I have used a brass punch and hammer to flatten out the damage on a boogered screw slot, it works OK if the damage is not too bad.

Thanks for the ideas....The gun is fine,its a mind thing!

I have done this many times; usually sufficient. Haven't checked lately, but sideplate screws from S&W didn't used to be very expensive.
