The weapon used to assassinate Archduke Franz Ferdinand was a Pistole Automatique Browning M1910. It had been designed by the American engineer Joseph Moses Browning and manufactured by Fabrique Nationale d’Armes de Guerre (National Factory of Weapons of War), a Belgian state-run company, located in Herstal, Belgium. The name of the factory is simply abbreviated as FN.
The assassination of the Archduke Franz Ferdinand took place at 10:45 am, on June 28, 1914, on Sunday. At that time, after his accomplice had just failed to kill the Archduke with a hand grenade, Gavrilo Princip, a Bosnian Serb, pulled out his FN Browning M1910, stepped up to the car that had just stopped and shot twice, killing him and his wife Sophie.
