Sight adjustment on pre-war targets

[austintexas]

Before I start fooling with the sights on my pre-war target S&W I need a little information, I think I know how to adjust for windage but how do you adjust for elevation? My rear sight had two small screws where modern Smiths have one. I've never had to fool with these early sights before and I don't want to break anything.

The forward of the two rear screws is the "Check elevation screw". It checks, as in STOPS movement.

LOOSEN it to start with- turn it to the left. If you loosen it too much, it will FALL OUT. Forget about it for now.

The rearmost screw is the elevation screw. Notice it has a FOOT that fits in a slot in the frame. It is a normal right hand thread. Turning it to the right RAISES the rear sight by jacking it up, so turning it left LOWERS the rear sight by pulling it toward the frame.

Once the rear sight is adjusted, turn the CHECK screw gently to the right and snug it against the frame. You are trying to put the two screws in a bind against each other to keep the elevation screw from moving.

I think I know how to adjust for windage

If you want to move left, loosen the LEFT screw, and IMMEDIATELY tighten the right screw. Leave either one loose, and your blade can FALL OUT.
If you want to move right, loosen the RIGHT screw, and tighten the left screw.

On a K22 OD without the check screw, you turn the screw to the right to raise the rear sight ?

Correct.
Standard right hand thread, so as it screws into the sight leaf, it causes the leaf to rise.

thanks Lee - didn't want to do any trial & error on this one, and the sight is currently bottomed out on the frame.

Thanks alot for the sight information, I would really hate to screw up a nice old revolver.

FIRST of all, get a hollow ground screwdriver that FITS perfectly. Not almost perfectly. Those little rascals are narrow. Good luck.
