This Lightweight Officer's ACP pairs a compact 3.5 in barrel with a steel slide and an aluminum-alloy frame to reduce weight while retaining .45 ACP performance. The slide and frame wear a matte dark finish, and capacity is 7+1 with the included Officer-length magazine.
It is a Mk IV/Series 80 configuration with a single-action, short-recoil operating system and the Series 80 firing-pin block. Controls include a single left-side manual thumb safety and a grip safety. The pistol uses a short, solid trigger and a Commander-style rowel hammer.
Sighting is handled by low-profile fixed 3-dot sights: an orange-painted front dot and a rear with two white dots. Vertical rear slide serrations provide traction for slide manipulation. The checkered wood grips with gold Colt medallions add classic Colt styling and a secure purchase.
Factory markings confirm authenticity: the right slide is rollmarked "LIGHTWEIGHT OFFICER'S ACP," the left slide reads "COLT MK IV" with the Rampant Colt and "SERIES 80," and the barrel hood is marked "COLT 45 AUTO." This example was made in Hartford, Connecticut, USA in 1989.
