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.
