SN: 8548. Made 1927-1928. .45 ACP with a 5"" barrel. Bore has strong rifling with minor frosting noted in the grooves. This Argentine Contract Colt 1927 was one of the first 10,000 pistols made In Hartford Connecticut at the Colt factory before being sent to Argentina, these pistols would later become known as the Sistema. The frame retains majority of the factory blue while much of the slide has transitioned to a brown patina. The grips show expected handling wear for a service pistol with largely dulled checkering while remaining in good condition. Overall good condition. (Consignment)
