Abstract

An improved revolver with a reduced barrel/cylinder gap (34) employs cylinder-chamber passages (54) through which bullets travel on route to the barrel bore (62) having diameters which are at least 0.005 inch greater than the diameter of the bullets. In this revolver the forcing cone (41) of the barrel bore (62) is at least one-half inch long and has a large-end diameter which is 0.025 to 0.035 inch larger than the bullet diameter. The cylinder/barrel gap (34) is less than 0.004 inch.
