Sight devices of many guns are not wholly satisfactory. When guns such as .45 caliber automatic pistols are to be used in competitive target shooting, more expensive gun sights are utilized. Simpler gun sights are available but they present visual problems. A rear gun sight apparatus is provided herein which improves visual sighting or aiming, and it can be readily manufactured at a low cost and by simple manufacturing methods.
