The Rock Island 51991 Rock Ultra FS delivers serious 10mm Auto performance in a full-size 1911 platform built for demanding applications. This pistol combines traditional 1911 reliability with modern enhancements that address the unique challenges of the powerful 10mm cartridge.
What Makes This Different
Unlike standard .45 ACP 1911s, the Rock Ultra FS features a reinforced frame specifically engineered to handle the higher pressures and velocities of 10mm ammunition. The 5-inch barrel maximizes the cartridge's ballistic potential while the serrated slide provides enhanced grip during manipulation. The black Parkerized finish offers superior corrosion resistance compared to basic blued steel, extending service life in harsh conditions.Key Features
