Overview
The Pistol Auto 9mm 1B is an Indian semi-automatic pistol manufactured by the Ordnance Factory Board at Rifle Factory Ishapore. It is a licensed copy of the Browning Hi-Power, produced using tooling originally acquired from the Canadian firm John Inglis and Company. The 1B is the commercial and civil-trade designation of the design, sharing the recoil-operated, hammer-fired, single-action mechanism and 13-round magazine of the military-issue 1A. Chambered in 9x19mm Parabellum, it serves as a service and personal-defence sidearm in Indian military, police, and civilian markets.
