The Brigadier is a pistol developed by the North America Arms Corporation (NAACO) to meet Canadian requirements for a service handgun in the aftermath of World War II. It was based largely on the FN GP35 Hi-Power self-loading pistol of 1935 but scaled up significantly. Whereas the Hi-Power used the 9×19mm cartridge, the NAACO Brigadier used a new long-case .45 inch round of greater length and much greater power than the then-standard .45 ACP.
