This 1997 Colt Officer’s ACP MK IV Series 80 is the factory bright stainless variant, identifiable by its SF serial prefix.

Colt introduced the Officer’s ACP as its first factory-produced 3.5 inch stainless 1911, giving shooters a true Colt compact without aftermarket alterations. The bright stainless finish on both frame and slide resists corrosion and makes maintenance straightforward.
The Series 80 system incorporates a firing-pin block that is disengaged only when the trigger is pressed, working in concert with the thumb safety and grip safety for layered protection without altering the crisp single-action pull.
Compact dimensions include the shortened grip frame and rowel hammer, aiding concealability while maintaining full .45 ACP ballistics. Three-dot sights—pinned blade front and dovetailed, drift-adjustable rear—offer a clear sight picture under varied lighting.
Discontinued after the late 1990s, this model has become sought after by collectors who value its place in Colt’s evolution of the 1911 platform. The excellent bore, minimal handling wear, and complete factory accessories enhance its appeal as a clean example of a milestone compact Colt.
