Armscor Rock Standard FS 1911 | .45 ACP | 5″ | 51448

The Rock Island Rock Standard FS is a full-size 1911-style semi-automatic chambered in .45 ACP with a 5-inch button-rifled barrel and a matte nickel finish. It features a full-length guide rod, low-profile dovetail front sight, fixed rear sight, and an extended beavertail grip safety paired with a skeletonized hammer and trigger. This configuration suits range work, target shooting, and traditional 1911-style competition where a full-size platform and .45 ACP ballistics are preferred. For those who wish to add a red-dot, a compact option such as a Leupold DeltaPoint Pro pairs well and remains under $1,000; note the slide is not drilled and tapped in current listings and will require proper mounting provisions.
