ABSTRACT:
An adjustable rear sight for handguns is disclosed wherein the sight is specially designed for easy interchangeability of its sight blade or leaf by removal of a minimal number of parts. The sight blade is removably held in a dovetail channel of the sight's main body by basically only a screw-headed pin or stop that fits into a groove in the head of the windage screw for the sight.
If a user desires to repair a broken blade or replace it with a new one having a different-sized sight notch, he merely unscrews the stop pin and slides the blade (with the attached windage screw) out of the main body. The screw is then placed in a new leaf and slid back into the channel, where it and the new leaf are securely held in place by screwing the pin back into the body.
