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. The standard barrel lengths available were the same as those for the Service-Six, but also included a 3" length in certain law-enforcement contract orders, until the agencies using the revolver ultimately adopted .40 cal. semi-automatic pistols.

Great powers have often used smaller conflicts as test beds for new weapon systems, and also as dumping grounds for obsolete machinery. The Spanish Civil War was one such conflict.
