Rock Island 51623 Rock Ultra FS 9mm 5" Barrel 10+1 Capacity

The Rock Island 51623 Rock Ultra FS delivers full-size performance in a competition-ready 1911 platform chambered in 9mm Luger. This tactical pistol combines traditional 1911 ergonomics with modern enhancements for serious shooters demanding reliability and precision.

What Makes This Different

Unlike standard 1911 models, the Rock Ultra FS features a tactical rail system for mounting accessories and an enhanced beavertail grip safety for improved hand positioning. The black Parkerized finish provides superior corrosion resistance compared to basic blued finishes, while the G10 grips offer better texture retention than traditional wood or plastic alternatives. The serrated slide design reduces glare and improves manipulation under stress.

Key Features

• 5-inch match-grade barrel for enhanced accuracy and velocity
• 10+1 capacity with single-stack magazine design

The enhanced grip safety and manual thumb safety provide multiple layers of protection during carry and handling.
