When the first all-steel small frame (J) revolver was introduced in 1950, it became an instant success. Originally named the Chiefs Special by the International Association of Chiefs of Police, it has become the first choice for those who insist on an allsteel, small frame revolver with greater recoil control and proven performance. This classic revolver is available in three hammer designs - the "Chiefs Special" with exposed hammer, the "Centennial" frame with fully enclosed hammer and the "Bodyguard" frame shrouded hammer.
