The Rock Island Armory GI Standard CS is a compact 1911-style pistol chambered in .45 ACP. Its 3.5-inch barrel provides a shorter carry profile while retaining the familiar single-action 1911 operating system. The steel frame and slide feature a durable black Parkerized finish that reduces glare and provides a practical protective surface. Smooth wood grips add a traditional appearance and comfortable hand contact, while fixed low-profile sights support a straightforward presentation from a holster. The pistol uses a manual thumb safety and offers a 6+1 capacity.
