The Global Response Pistol is Nighthawk's duty-grade 5-inch 1911 built to the specification of law enforcement and security professionals who needed a 1911 with modern duty features and absolute reliability. The GRP ships with a Picatinny rail, dehorned profile, night sights, and Nighthawk's one-gun, one-gunsmith fit standard. Units who issued it found it required none of the armorer work typically needed to make a 1911 duty-ready.
