The Rock Island 51914 Tac Ultra FS 10mm Auto Caliber with 5" Barrel is a full-size 1911 platform pistol engineered for tactical applications, duty carry, and serious shooters who demand the stopping power of 10mm in a proven operating system. Built on Armscor's established TAC series platform, this firearm combines precision engineering with modern tactical features designed for law enforcement, security professionals, and experienced operators seeking a capable defensive or range platform.
The 5-inch barrel delivers consistent velocity performance and accuracy inherent to the 1911 design while maintaining a manageable profile. The 8+1 capacity (8 rounds in magazine, 1 in chamber) reflects traditional 1911 single-stack magazine configuration. Tactically relevant features include a full-length Picatinny rail mounted to the frame for modern optic and light systems, a serrated slide for positive grip in adverse conditions, and a beavertail frame design that protects the hand during firing while providing ergonomic grip purchase. The black parkerized steel finish offers proven corrosion resistance suitable for duty environments. Skeletonized hammer and trigger with overtravel stop allow fine-tuning of trigger geometry and reset characteristics—critical adjustments for precision shooting and rapid follow-up accuracy. Black/gray G10 grip scales provide texturing and durability in wet or gloved operations.
This platform serves operators requiring 10mm ballistics, shooters upgrading from standard duty calibers, tactical trainers building versatile 1911 systems, and pistol competitors valuing single-action ergonomics and customization potential. The Picatinny rail accommodates weapon lights, laser systems, and optical mounts without requiring frame modifications. The 1911 platform ecosystem provides extensive aftermarket support for sights, triggers, grips, and internals, making this a foundation for configuration tailored to specific mission profiles.
The 10mm cartridge delivers higher velocity and energy than 9mm Parabellum, with standard loadings propelling full-power rounds to velocities around 1,200 fps from a 5-inch barrel. This translates to reliable expansion performance and deep penetration through intermediate barriers. The Rock Island Tac Ultra FS represents a mature, field-proven platform for users prioritizing capability and tactical modularity over high-capacity magazine systems.
