Built on the 1911 platform, this full-size Government Model pairs a 5-inch barrel with a 9+1 capacity in .38 Super. It uses a single-action, locked-breech system with a short, solid trigger featuring vertical serrations and a spur hammer.
The pistol retains hallmark Series 70 features: no firing pin block, a standard (un-lowered) ejection port, rear-only vertical cocking serrations, a standard barrel bushing profile, and a recoil spring plug with a checkered face. The blued finish presents polished slide flats contrasted by matte rounded surfaces on the slide.
Sighting is straightforward and robust, with a staked front blade and a square-notch rear. The wood grip panels with Colt medallions complement the carbon steel, blued frame. Safety features include a manual thumb safety and grip safety.
Factory markings are crisp and model-specific: left slide reads "COLT'S MK IV/SERIES '70 – GOVERNMENT MODEL – .38 SUPER AUTO CALIBER" with the Rampant Colt logo; right slide reads "COLT'S GOVERNMENT MODEL"; the chamber hood is marked "COLT SUPER .38 AUTO – MK.IV/SERIES '70"; and the frame carries the Hartford, Connecticut address line. Production is dated to 1975, aligning with the 70Sxxxxx serial-number pattern associated with .38 Super Government Models of the Series 70 era.
