It has a serrated matte top and side polished stainless steel spur hammer, grooved trigger, 7-shot magazine, grip and thumb safeties, and checkered walnut grips with gold plated Rampant Colt medallion inlays on both sides. The right side of the slide is marked, "COLT'S GOVERNMENT MODEL", with the one-line address and serial number stamped below on the frame, and the left side of slide being marked, "COLT MK IV/SERIES '70/GOVERNMENT MODEL/.45 AUTOMATIC CALIBER" followed by the Rampant Colt.
