Across the rugged Indian Territory, rides a tall young man on a mission of mercy; his medical bag strapped on one hip and his six-shooter on the other. This is Dr. Sixgun. Grey Matson, M.D. was the gun-toting frontier doctor who roamed the length and breadth of the old Indian territory; friend and physician to white man and Indian alike, the symbol of justice and mercy in the lawless west of the 1870s.” Dr. Sixgun is an American Western radio drama that aired on NBC from September 2, 1954 to October 13, 1955 as a 30-minute sustaining series. All known surviving episodes of Dr. Sixgun are from rebroadcasts from the Far Eastern Network in Japan of the Armed Forces Radio Service
