It was the Browning FN 1910 that Gavrilo Princip, a Bosnian Serb nationalist, used to shoot Archduke Franz Ferdinand, heir presumptive to the throne of Austria-Hungary, and his wife Sophie, as their motorcade passed through Sarajevo, killing both the date was June 28, 1914.
The terrorist act gave Austria-Hungary the excuse that it had sought for opening hostilities against Serbia and thus precipitated World War I.
With its compact design, it was a perfect assassin’s weapon. A M1910 also claimed the lives of Paul Doumer, the president of France, in May 1932, and Huey Long, the governor of Louisiana, in September 1935.
(not this very one however, this one from my collection)
