This Series 70 Gold Cup carries the 70N serial prefix, confirming 1973 production within the first four years of the model’s 1970–1983 run. Early-run pistols like this one retain the highly polished Royal Blue finish that became a hallmark of Colt’s premium lines.
The pistol’s match-grade National Match barrel partners with the Accurizer collet bushing—unique to Series 70 Gold Cups—to enhance barrel-to-bushing fit and promote repeatable lock-up. Together, they underpin the accuracy reputation that made the model a staple on competition lines.
Target-focused features include the skeletonized, wide trigger with over-travel adjustment, a flat-top slide with longitudinal serrations, and the Elliason fully adjustable rear sight combined with a plain Patridge front blade. These components allow precise sight alignment and trigger control essential for bullseye and NRA Precision Pistol disciplines.
The wide serrated target hammer, thumb safety, and grip safety retain the familiar 1911 manual of arms, while the checkered walnut grips with gold Colt medallions provide secure purchase and classic aesthetics.
Steel construction throughout—carbon-steel frame, slide, and 5-inch barrel—delivers the weight and durability favored by serious competitors. Chambered in .45 ACP, the pistol feeds from a single-stack 7-round magazine, maintaining traditional 1911 ergonomics.
