Luger / Parabellum Photos
The 9x19mm Parabellum is a pistol cartridge introduced in 1902 by the German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) for their Luger pistol. Its parent cartridge was the 7.65x22mm Parabellum, itself a descendant of the earlier 7.65x25mm Borchardt cartridge. The 9 mm Parabellum is used in pistols, submachine guns, and carbines.

The name Parabellum is derived from the Latin: Si vis pacem, para bellum ("If you seek peace, prepare for war"), which was the motto and telegraphic address of DWM.

Georg Luger developed the 9 mm Parabellum cartridge from the earlier 7.65 mm Parabellum pistol cartridge. In 1902, Luger presented the new round to the British Small Arms Committee as well as three prototype versions to the U.S. Army for testing at Springfield Arsenal in mid-1903. The German military expressed official interest in a 9 mm version of the Parabellum in 1904.

The initial cartridge was created by removing the bottleneck of the 7.65 mm Luger cartridge, resulting in a tapered rimless cartridge. The ogive of the bullet was slightly redesigned in the 1910s in order to improve feeding.
After World War I, acceptance of this caliber increased and 9 mm pistols were adopted by a number of countries.

To conserve lead during World War II in Germany, the lead core was replaced by an iron core encased with lead. This bullet, identified by a black bullet jacket, was designated as the 08 mE (mit Eisenkern - "with iron core"). By 1944, the black jacket of the 08 mE bullet was dropped and these bullets were produced with normal copper-colored jackets. Another wartime variation was designated the 08 SE bullet and identified by its dark gray jacket, and was created by compressing iron powder at high temperature into a solid material (Sintereisen - "sintered iron").

During the period between the early 1980's and the mid-1990's, a sharp increase in the popularity of "Wonder Nines" coincided with the adoption of the Beretta M9 by the US Army. At the time, most police departments were issuing .38 Special caliber revolvers with a six-shot capacity. The .38 Special was advantageous because it offered low recoil, the revolvers were small and light enough to accommodate different shooters, and it was relatively inexpensive. Possessing similar ballistics to the .38 Special revolver cartridge, the 9 mm is a shorter round, so extra ammunition carrying capacities could be easily increased by as much as 250%. The 9 mm pistol cartridge can be accommodated in a compact frame pistol, able to be used more effectively by inexperienced shooters and smaller-framed officers.
Attempts to improve ballistics of the cartridge came in the early 1990s with the widespread availability of high pressure loadings of the 9 mm cartridge. Such cartridges are labeled "+P" or in the case of very high pressure loadings "+P+". Ballistic performance of these rounds was moderately improved over the standard loadings.

The .40 S&W round debuted at the 1990 S.H.O.T. show. The .40 S&W sought to fill the gap between 9 mm and .45 ACP. While increasing bullet diameter to roughly half the difference between 9 mm and .45 ACP, the .40 S&W retained the same SAAMI standard pressure load limits of the 9 mm (240 MPa, 35,000 PSI). This afforded only a 20% (typical) capacity loss when compared to the 9 mm.
