FN 509 Comparison

Hickok45 Comparing three models of the FN 509.

FN Herstal originated in the small city of Herstal, near Liège. The Fabrique Nationale d'Armes de Guerre (French for National Factory of Weapons of War) was established in 1889 to manufacture 150,000 Mauser Model 89 rifles ordered by the Belgian Government. FN was co-founded by the major arms makers of the Liège region, with Henri Pieper of Anciens Etablissements Pieper being the driving force and the primary shareholder of the new company. In 1897 the company entered into a long-lasting relationship with John Moses Browning, a well-known firearms designer. FN was an important manufacturer of motor vehicles in Belgium, a development championed by Alexandre Galopin as managing director. Cars were produced in Herstal in the early 1900s until 1935. Production of FN motorcycles continued until 1965, and production of trucks until 1970. In 1973, FN changed its name to reflect a product line diversified far beyond just "weapons of war", adopting the current name of Fabrique Nationale d'Herstal.

One of Fabrique Nationale's handguns, a Model 1910 semi-automatic pistol in 9×17mm (.380 ACP) (serial number 19074) was one of four weapons that were taken from the assassins of Archduke Franz Ferdinand of Austria, although it is unknown which of the four weapons fired the fatal round.

John Moses Browning began development of the Browning GP35 'High Power' (sometimes written as Hi-Power) pistol, the GP standing for Grande Puissance or "high power" in French. However, the weapon was finalized by Dieudonné Saive and did not appear until nearly a decade after Browning's death.

The FN Manufacturing LLC plant in Columbia, South Carolina is part of the military division of FN. It is primarily responsible for the production of U.S. military weapons, such as M16 rifles, M249 light machine guns, M240 machine guns, and M2 machine guns.
