The Rock Standard Mid-Size is built in traditional classic 70 series design and delivered with Rock Island's top quality production and engineering standards. Like all Rock Island 1911s, each is built using 4140 ordinance steel on the industry's best CNC machines while being hand-fitted and tested to strict tolerance guidelines for unmatched quality and value.

It's chambered in 45 ACP with a 4.25" button rifled barrel supported by a full length guide rod. Smooth, angled, snag-free style allows for quick draw in fast need situations. Includes a low profile angled rear sight along with skeletonized hammer and trigger with adjustable over travel stop and ambidextrous safety standard in the Rock series.
