FN HP-DA (Hi-Power Double Action) is a 9mm semi-automatic pistol developed by Belgian Fabrique Nationale arms factory in Herstal. In North American markets, it was marketed as the Browning BDA (Browning Double Action, also BDA9) and is also referred to as Browning DA and Browning Hi-Power BDA.
Introduced in 1983, it is an update of the Browning Hi-Power (a.k.a. GP 35 in Belgium and French-speaking countries). The overall design layout of all versions of the pistol is based on the Browning Hi-Power, but the firearm features significant ergonomic changes designed to update the weapon to military requirements of its time.
