H&K MP7

The Heckler & Koch MP7(Maschinenpistole 7) is a German personal defence weapon (PDW) designed and manufactured by Heckler & Koch (H&K) and chambered for the HK 4.6×30mm cartridge. It was designed with the new cartridge to meet NATOrequirements published in 1989, as these requirements call for a personal defense weapon (PDW) class firearm, with a greater ability to penetrate body armorthan current weapons limited to conventional pistol cartridges. The MP7 went into production in 2001. It is a direct rival to the FN P90, also developed in response to NATO's requirement. The weapon has been revised since its introduction and the latest production variants are the MP7A1 and MP7A2.

The MP7's 4.6x30mm cartridge is a high-velocity round specifically designed to pierce armor. Therefore, 4.6x30mm rounds are always considered to be AP rounds. The armor-piercing quality of the ammunition is already figured into the MP7's statistics.
