Colt Police Positive

The Colt Police Positive is a small-frame double-action revolver featuring a six-round cylinder, chambered for either .32 or .38 caliber cartridges. Designed primarily for sale to federal, state, or local law enforcement agencies, the Police Positive was introduced into the firearms market by the Colt's Manufacturing Company in 1907. The Police Positive was very successful; along with the Colt Official Police it dominated the law enforcement firearms market in the early 1900s.[4] The Positive was itself incrementally modified in 1908, forming the basis for Colt’s Police Positive Special model.[2]

A nickel Police Positive with pearl grips was used by Charles Bronson as Paul Kersey in Death Wish. The notorious American gangster Al Capone also used a Police Positive, a nickel .38 Police Positive with walnut grips and a 4 inch barrel, manufactured in 1929.
