Rock Island Armory TAC Ultra MS 10mm 4.25" 8+1 Capacity Pistol

The Rock Island Armory TAC Ultra MS 51994 delivers serious 10mm Auto performance in a tactical-ready package built for demanding applications. This full-size pistol combines proven 1911 reliability with modern tactical enhancements that address real-world shooting requirements.

What Makes This Different

The TAC Ultra MS stands apart from standard 1911 pistols through its integrated Picatinny rail system and enhanced grip texturing. Where traditional 1911s require aftermarket modifications for accessory mounting, this pistol ships ready for lights and lasers. The black Parkerized finish provides superior corrosion resistance compared to basic blued steel, extending service life in adverse conditions.

Key Features

• 10mm Auto chambering delivers 40% more energy than .45 ACP for maximum stopping power
• 4.25-inch barrel optimizes velocity while maintaining manageable overall length
• Integrated Picatinny rail accepts standard tactical accessories without gunsmithing
• Black/gray G10 grips provide superior traction in wet conditions compared to wood or plastic
• Serrated slide reduces glare and improves manipulation under stress
• Beavertail grip safety eliminates hammer bite while maintaining drop safety
• 8+1 capacity balances firepower with reliable feeding

The 10mm Auto cartridge excels in roles where maximum terminal performance matters most. Law enforcement agencies favor this caliber for its ability to penetrate barriers while maintaining expansion. Hunters appreciate the flat trajectory and energy retention for medium game at extended ranges. The TAC Ultra MS handles full-power 10mm loads that would punish lighter-framed pistols, maintaining accuracy through extended shooting sessions.
