Browning Hi-Power Wiki

The Browning Hi-Power is a single-action, semi-automatic handgun, introduced in 1935. Initially designed by John Browning for FN Herstal, and completed by Dieudonné Saive after his death.
It was the first handgun design that features a standard double-stack magazine containing thirteen 9×19mm rounds, the origin of "High Power" naming in allusion to the higher capacity.
