Gen III Colt Single Action Army new in the box! .45 Colt caliber. 4 5/8" BBL. Serial #SO_ _ _ _ A This revolver has not been shot or even cocked since leaving the factory. It has color case hardened frame and Colt Royal Blue finish. It has factory Stag grips. My research indicates this gun came out of the Colt Custom Shop since they were the only ones doing the Stag grips and Royal Blue finish at the time. Box is pristine and all original factory paperwork is included. A perfect BBQ gun! No trade offers please. Cash deals only.......got too many damn guns now!
