The Compact Model follows the Officer/Compact-size 1911 pattern with a 3.5-inch barrel and single-stack 6+1 capacity. Its steel frame and slide wear a matte blued finish, and the smooth front strap pairs with a flat mainspring housing for a traditional 1911 grip profile.
This is a Series 80 pistol with a firing pin block, single-action operation, and a single-side (left) manual thumb safety. It also includes a grip safety and a Commander/rowel-style hammer, delivering the familiar 1911 control layout.
Sighting is straightforward and durable: a fixed 3-dot set with a single white-dot front blade and a two-dot rear in a dovetail. The slide features rear cocking serrations only, and the pistol wears black checkered grips with Colt medallions.
Markings and period details stand out. The slide is rollmarked "COLT M1991A1" and "COMPACT MODEL" in the early-1990s Old Rollmark style. Production aligns with the CP-prefix serial range used for Compact models, and this example was manufactured in 1995 in the USA.
