Colt National Match with adjustable sights, Swartz safety, factory nickel finish and checkered walnut grips. The Colt factory letter says it shipped with the nickel finish on September 10, 1938. The letter also indicates that the pistol was furnished with a safety device and adjustable rear sight. Shipped to Wolf & Klar Wholesale Sporting Goods, Ft Worth, TX as a single gun shipment. The Swartz safety is a device that blocks the firing pin when the grip safety is not engaged. It is NOT the same as the series 80 fire control system.
