An answer to Colt's Detective Special and Smith & Wesson's Chiefs Special, the Ruger Speed-Six revolver was intended for use by plainclothes detectives and others desiring a more concealable handgun. The revolver, a variant of the Ruger Security-Six and Service-Six, incorporates fixed sights and a round-butt frame, and was available in .357 Mag., .38 Spl., .38 S&W (.380-200), and 9 mm Luger.
