FN Model 1910

The FN Model 1910, also known as the Browning model 1910, was a departure for Browning. Before, his designs were produced by both FN in Europe and Colt Firearms in the United States. Since Colt did not want to produce it, Browning chose to patent and produce this design in Europe only. Introduced in 1910, this pistol used a novel operating spring location surrounding the barrel. This location became the standard in such future weapons as the Walther PPK and Russian Makarov.

It incorporated the standard Browning striker-firing mechanism and a grip safety along with a magazine safety and an external safety lever (known as the "triple safety") in a compact package. Offered in both .380 ACP (6-round magazine) and .32 ACP (7-round magazine) calibres, it remained in production until 1983. It is possible to switch calibres by changing only the barrel. However, FN never offered packages containing a single pistol with both calibre barrels.

The FN Model 1922 was also used by the Kingdom of Yugoslavia (60,000 Automatski pistolj (Brauning) 9mm M.22) between 1923 and 1930.

An FN M1910, serial number 19074, chambered in .380 ACP was the handgun used by Gavrilo Princip to assassinate Archduke Franz Ferdinand of Austria and his wife Sophie in Sarajevo on 28 June 1914, the act that precipitated the First World War. Numerous previous sources erroneously cited the FN Model 1900 in .32 calibre as being the weapon Princip used. This has led to confusion over the calibre of the pistol actually used.

Paul Doumer, President of France, was assassinated by Russian emigre Paul Gorguloff on 6 May 1932 with a Model 1910 in .32 ACP. The pistol is now in the Musée des Collections Historiques de la Préfecture de Police.

A Model 1910 was also allegedly used to assassinate Huey Long, governor of Louisiana, on 5 September 1935. Physician Carl Weiss, the alleged assassin, bought the FN M1910 in Europe for $25 in 1930. It is now on display Old State Capitol in Baton Rouge.

Hannie Schaft used a model M1922 during her assassinations as part of the Dutch communist resistance against German occupation of the Netherlands.
