Gunsite is a privately run firearms training facility based in Yavapai County, Arizona, just south-west of Paulden in the United States.
Located on a 3,000-acre (12 km2) facility, Gunsite has classrooms, indoor and outdoor firing simulators, and various pistol and long-barrel ranges.
[1] Gunsite was founded by Jeff Cooper as the American Pistol Institute (API) in 1976 in order to teach the modern technique of shooting.
Prior to the founding of API, Cooper had traveled the world providing training in the modern technique to security teams such as those protecting heads of state, prominent politicians and wealthy individuals.
[citation needed] Under the new owner the instruction shifted away from modern technique as taught by Cooper, both in content and quality and the school was not well regarded.
During this time Cooper held classes occasionally at the National Rifle Association of America's Whittington Center in New Mexico and other locations.
