"Rock Island has a sterling reputation for creating high-performance 1911s, and the Rock Island Armory M1911-A1 GI Standard FS 9mm Semi-Auto Pistol applies that expertise to a fantastic representation of the original GI variant. Of course, unlike the original, it's chambered in 9mm, so you get 2 extra rounds in the same grip frame. The frame and slide are made from 4140 ordnance steel and refined by Rock Island's carefully managed hand-fitting process for superior precision. A durable Parkerized finish gives it a durable, corrosion-resistant, and great-looking surface. True to all Rock Island Armory, the GI Standard FS comes with a crisp 46 lb. factory trigger. Checkered rubber grips. 5"" barrel. Fixed combat sights. Beavertail grip safety and manual thumb safety.
