COLT MKIV SERIES 80 OFFICERS

Colt MK IV Series 80 specifications vary significantly by model but generally include a semi-automatic, short-recoil action and the defining feature of a firing pin block safety. Key differences depend on the model, with common variations including the Government (5-inch barrel, .45 ACP or 9mm), Officer's (shorter 3.5-inch barrel, .45 ACP), and Commander (4.25-inch barrel, .45 ACP, 9mm, or .38 Super) models, each with different capacities and features like adjustable or fixed sights.
