Richards Conversion, 1860 Army Revolver
Colt's second attempt at metallic cartridge conversion. It met with quite a bit more success than the first. Richards Conversion was designed for .44 Colt cartridge. Has a 6-shot cylinder and an integral ejector rod to replace the loading lever that had been removed. Other specifications pertaining to 1860 Army Revolver remain as previously described, if they are not directly altered by the conversion. Richards Conversion adds a breechplate, with a firing pin and its own rear sight. Approximately 9,000 of these Conversions manufactured between 1873 and 1878. NOTE: Blued models will bring higher prices than nickel models in the same condition.
