The very first Colts were the same, though gateless, the loading lever equipped percussion guns, 1847, 1848, 1849, 1851, 1860/61, conversions and the 1871/2 opentop were all loaded or capped on the right side, so the left hand had to hold the gun. The 1873, though Sam Colt had died, was mechanically identical except for being a cartridge revolver.
