Built on the compact Officer's-size 1911 platform, it uses a 3.5 in barrel and a short grip frame for a 7+1 capacity in .45 ACP. It runs a single-action, short-recoil operated system with the Series 80 firing-pin block, combining classic 1911 ergonomics with enhanced internal safety.
The pistol presents a two-tone finish with a dark slide over a bright high-polish silver frame. Factory markings include 'ULTIMATE OFFICERS .45 ACP' on the right side of the slide and 'COLT MK IV' over 'SERIES 80' with the Rampant Colt logo on the left. The slide has vertical rear-only serrations, and the recoil spring plug is checkered.
Sights are fixed; see photos for configuration. Controls include a single-side thumb safety and a grip safety, and the hammer is the Commander-style rowel type. The pistol currently wears checkered wood double-diamond grips.
