Lightweight, Maneuverable, Ergonomic 9mm Carbine: Wilson Combat AR9G
The 5.56mm NATO caliber AR-15 holds sway for police patrol rifles, but 9mm shoulder-fired weapons occupy a place in many armories, typically as submachine guns. Carbines such as the Beretta CX4 are used by several state university police departments, while a few sheriff’s departments use the CZ EVO.
