History
Following the Civil War, the US military sought to convert from percussion cap-and-ball arms to the new metallic cartridge technology. The Navy adopted Remington's rolling block pistol in 1866, chambered for this large-bore rimfire. The rolling block action was among the strongest single-shot actions of its era. The .50 Remington Navy provided a substantial step up from the earlier .44 Henry in a handgun-sized package. The cartridge was superseded as the Navy transitioned to centerfire designs in the 1870s. Original Navy rolling block pistols in shootable condition are highly sought by collectors of US martial arms.
