Rock Island 51700 | TAC Ultra CS | 9mm | 8+1

The Rock Island Armory TAC Ultra CS is a compact, steel-frame 1911-style pistol chambered in 9mm and configured for tactical versatility and modern carry. It features a Picatinny under-rail, black parkerized finish, and black/gray G10 grips for a firm, ergonomic hold. For a compatible optic under $1,000 consider a compact red-dot such as the Holosun 507K for fast sight acquisition and low-profile mounting.
