Lineage
History
Developed by John Browning for FN's Model 1903 semi-automatic pistol. The Swedish military adopted the M1903 as the Pistol m/07 and used the 9mm Browning Long as their standard service pistol cartridge from 1907 until 1940, when they transitioned to 9mm Luger. The cartridge was also adopted by the Belgian Gendarmerie. Swedish military ammunition is common in European collections; factory production has entirely ceased.
