"Machine Gun" Kelly was one of the most wanted gangsters of the 1930s. He had a special expression for the FBI agents hunting him: G-Men. The Hollywood film of the same name made the men working for the Government world-famous - and their service revolver into a legend. Smith & Wesson created a new class with this revolver model: the snubbies. Gun users all over the world still call the "snub-nosed" revolvers their "life insurance". As a gas signal gun, the S&W Chiefs Special is a strong revolver in a large caliber.
