The Officer's ACP format delivers a compact stainless-steel slide and frame paired with Colt's Series 80 firing-pin block system. This variant follows the MK IV/Series 80 pattern and retains classic 1911 controls in a reduced package chambered in .45 ACP.
The 3.5-inch heavy bushing barrel and dual recoil-spring assembly are designed for the compact Officer's-length system. Rear-only vertical slide serrations provide a straightforward gripping surface, and the Commander-style ring hammer complements the compact configuration.

Wrap-around Pachmayr rubber stocks with Colt medallions add traction and comfort. The stainless construction is denoted by the SF serial prefix, and the pistol is built in the USA. Capacity is 7+1 with the included single-stack magazine.
