Talking about target sights, the 2 screw rear sight would represent a third type of rear sights made for the pre-WWII K22s 1st Models. As Jim states, a second screw was added to help hold the rear sight in place in the mid-1930s. It was thought that the single screw sight height adjustment was subject to movement during prolonged shooting, so a "lock screw" was added to keep the gun on target. That second screw had a slot in the frame in front of the elevation screw that allowed the shooter to tighten the sight against the elevation screw, thereby holding the sight on target and make minute adjustments possible. I recently purchased such an K22 Outdoorsman's revolver that shipped in 1936 and Ralph helped me to understand how the sight worked. How did I do Ralph?
