The Cimarron 1851 Richards-Mason Conversion single-action revolver is one of the best replicas ever manufactured. The 1851 Richards-Mason revolver was a conversion of the 1851 Colt percussion revolver to a breech-loaded self-contained metallic cartridge. Due to the scarcity of original models the Cimarron 1851RM is a favorite of modern-day shootist. The Wild Bill Hickok model is nickel plated and highly engraved with ornate scroll-work. The backstrap features a W.B. Hickok signature with attractive poly ivory grips. - Single Action Revolver - .38 Special - 6 Rounds - 7-1/2 Barrel - Fixed Front Sight - Nickel Plated - Ornate Engraving - Poly Ivory Grips - W.B.
