“There can be no question that probably the deadliest handgun ever was the Model 1910 7.65mm (.32 ACP) FN Browning auto pistol used by Bosnian anarchist Gavrilo Princip to assassinate heir to the Austro-Hungarian throne, Archduke Franz Ferdinand,” gunsandammo.com states, brooking no opposition. Negating debate. Strangling discussion in its metaphorical crib. No question. Probably. “Princip ambushed the archduke and his entourage on June 28, 1914 in Sarajevo, killing him and his wife Sophie. This sparked off a series of events resulting in World War I and military and civilian casualties totaling some 37,000,000.” Although I own a Colt 1903 (the 1910’s predecessor), I’d still rank my FN SCAR as a deadlier weapon. But then, gunsandammo would probably call me a hopeless pedant. Or vice versa.
