6/20/17 - This is an excellent Colt Official Police, manufactured in 1942, as shown on the Colt factory letter that accompanies this revolver. The original bluing rates at about 97%, with the wear found on either side of the muzzle, as well as the visible roll marks. The revolver is all correct and matching with a minty bore. Introduced to the firearms market in 1927, the Colt Official Police is a medium frame, double-action revolver with a six-round cylinder, primarily chambered for the .38 Special cartridge, and manufactured by the Colt's Manufacturing Company. The intended specific target market for the Official Police was mainly law enforcement agencies and it became one of the best selling police firearms of all time, eventually in the 1950s coming to exemplify typical peace officer weaponry. The Official Police was also used by various U.S. and allied military forces during World War II.
