Ammunition, Missiles and precision weapons

A rimless, straight-taper brass case, Berdan primed. The bullet is ogival, lead-cored with steel jacket and gilding metal envelope, and weighs 8.75 g. It should be noted that the obsolete 9 mm Steyr cartridge is of almost identical dimensions and can only be distinguished by the bullet, which has a steel jacket and is somewhat more pointed, and of course, by the Austrian headstamp. Designed by Theodor Bergmann and Hugo Schmeisser for Bergmann's 1903 pistol, which was subsequently adopted by the Spanish and Danish

armies. Although the pistols are long obsolete in both forces, the cartridge was retained in Spanish service and many subsequent military and police weapons used it until replaced by the 9 mm Parabellum in the 1980s. Many Spanish police and security forces still use weapons chambered for this round. Applications include bergmann-Bayard and Astra pistols in Spanish and Danish service; Bergmann M28 and M34 sub-machine guns; Star sub-machine guns.
