The gun used in the series is actually a replica Paterson modified to fire metallic cartridges. The gun was described as being built in 1835, before Colt made firearms, and fires metallic cartridges which were never made to fire in a Colt revolver until 10 years after Samuel Colt's death. On the barrel of the gun is inscribed the Latin phrase "non-timebo mala", meaning "I will fear no evil". On the grip is a carving of a pentagram, with much of the finish removed to give it an aged appearance. The prop department also has a rubber version of the Colt to be used in fight scenes for pistol-whipping.
