Abstract
Abstract A safety indicator is disclosed for use with a revolving chamber cylinder of a revolver. The indicator comprises a static marker which is positioned or manufactured on an external surface area of the revolving cylinder. The external area corresponds to the location of a predetermined chamber of the revolving cylinder which is to remain empty while loading the remaining chambers with bullets. After loading the revolving cylinder, the static marker, and hence the empty chamber, is aligned with the barrel and firing hammer of the revolver in accordance with the accepted and safe practice of carrying a revolver with the hammer on an empty chamber to discourage accidental discharge.
