These early Colt conversions were the first large caliber cartridge pistols that Colt produced and were very popular on the western frontier. They were mfg.d from 1871 to 1878 when the West was still pretty wild and being settled by Civil War veterans. This pistol certainly has a cowboy /gunfighter look about it. The barrel has been reduced from it’s original 7 1/2″ to 5 1/4″. This was professionally done and they even utilized the original front sight. The action is a little worn but locks up nicely. The cylinder exhibits a full scene with the Engaged 16, May 1843 still very sharp. Both sides of the grips have period notch’s cut into them . They are well worn and been there along time. The pistol still retains a good amount of it’s nickel finish on both the barrel and backstrap. A great looking 1870’s western pistol.
