The .9mm Browning Long Ammo is a centerfire pistol cartridge, military-grade. It was designed and developed in 1903 for the FN Model 1903. The .9mm Browning Long Ammo is pretty similar to the 9x19mm Parabellum Ammo, but it has a slightly longer casing and is semi-rimmed. Simply using the 9x19 Parabellum Ammo in the FN Model 1903 would have required a locked-breech design. The cartridge was produced for many major countries and was used in World War I by Germany and Ottoman Empire. However, in modern days, the .9mm Browning Long Ammo has become obsolete since it is hard to find a reloadable brass for this bullet. One accessible option the hand loaders have is to shorten the .38 Super. In 2000, the .9mm Browning Long Ammo was manufactured in Siberia by Prvi Partizan. The overall length of the .9mm Browning Long Ammo is 28mm, and the bullet diameter measures 9.09mm. The 108-grain bullet variant can travel at a velocity of 1,150 feet per second while creating an energy level of 316 ft.lbf.
The .9mm Browning Long Ammo was designed and manufactured by John Moses Browning in 1903.
The .9mm Browning Long Ammo has been mainly used for military purposes in the past and was even used in World War I.
