Colt Gold Cup National Match Mk IV Series 70 .45 ACP – 5" National Match Barrel, 1980 Production, Competition-Focused with Slide-Mounted Optic Rail
The Colt Gold Cup National Match has long set the standard for competition-grade 1911 pistols, and this 1980-dated, Mk IV Series 70 example stays true to that legacy. Featuring the factory National Match barrel, collet-style bushing, and a tightened slide-to-frame fit, it is engineered for accuracy. An aftermarket slide-mounted Picatinny/Weaver rail and a right-side grip rail expand optic options without altering the pistol’s proven performance pedigree.

Built for competition, the Gold Cup National Match blends Colt’s Series 70 accuracy features with a smooth, single-action trigger. The factory skeletonized, three-hole trigger includes an adjustable over-travel stop and breaks at approximately 4 lbs for precise shot control.
The 5" National Match barrel partners with the collet-style bushing unique to Series 70 production, delivering tight lock-up and repeatable accuracy. Rear vertical cocking serrations and a wide target hammer aid positive manipulation between stages.
High-polish blued carbon-steel construction gives the pistol a classic appearance while the Elliason adjustable rear sight and removable front blade offer fine elevation and windage control. For shooters preferring optics, the slide-mounted Picatinny rail and grip-mounted side rail provide secure, low-profile mounting surfaces.
Serial prefix 70N dates this pistol to 1980—the final Gold Cup iteration before the Series 80 firing-pin block redesign—making it desirable for collectors who favor the original action geometry.
