The Combat Commander is Colt's steel-frame, shortened 1911 pattern with a 4.25 inch barrel. This example is configured in MK IV/Series 80, integrating a passive firing-pin block for added drop protection while maintaining the single-action, short-recoil operating system.
Built with a stainless steel slide and frame, it features vertical rear slide serrations and a classic GI barrel bushing paired with a checkered recoil spring plug. The mainspring housing is flat (straight backstrap) and vertically serrated, with a smooth front strap for a traditional Commander feel.
Controls and small parts align with a period-correct setup: a Commander ring (rowel) hammer, a short, solid trigger, and both grip and manual thumb safeties. Sights are fixed, with a ramped front and square-notch rear.
Grips are checkered double-diamond walnut with gold Colt medallions. Capacity is 7+1 with the included 7-round magazine. The factory box bears finish code "STS" for stainless and a serial-matching label, and the package includes the Colt safety manual and owner/welcome letter.
