The Government Model .380 Mk IV/Series 80 brings the 1911 platform to a compact .380 ACP format while keeping hallmark features such as a manual thumb safety, grip safety, and a Series 80 firing-pin block. The short, solid, smooth-faced trigger and Commander-style rowel spur hammer provide a classic Series 80 control layout.
The stainless steel slide and frame use vertical rear serrations for confident manipulation. Sighting is straightforward and durable, with a fixed blade front and a dovetailed fixed-notch rear.
Internally, the pistol is locked-breech and recoil-operated, and it retains the 1911-type barrel bushing and plug. Capacity is 6+1 with its single-stack magazine.
Dimensions and handling are compact and carry-friendly: a 3.25-inch barrel, approximately 6.5 inches in overall length, and about 21.75 ounces in weight. This stainless configuration was commonly cataloged as model O6080 and was part of a discontinued production run from the 1980s–1990s.
