Although it appears to be a conversion, the model 1872 Open Top was Colt's first revolver specifically manufactured to fire a cartridge. Since Colt did not use percussion revolver parts, the revolver was manufactured as an entirely new model, first with Navy-sized grips, later with Army-sized grips. All come standard with case-hardened frame and blue barrel finish. Nickel finish frame and barrel are available; add N00 to model number.
