MP7

The Heckler & Koch MP7 (German: Maschinenpistole 7) is a personal defense weapon chambered for the HK 4.6×30mm armor-piercing cartridge designed by German defence manufacturer Heckler & Koch. It was designed together with the new cartridge to meet NATO requirements published in 1989, which called for an SMG-type weapon that had a greater capacity to defeat Kevlar body armour than pre-existing submachine guns using conventional pistol cartridges such as .45 ACP and 9×19mm Parabellum.
