Heckler and Koch MP7

Heckler and Koch MP7

Smaller than a conventional submachine gun, the 4.6mm MP7A1 is a compact and lightweight Personal Defense Weapon that can be carried like a handgun yet is capable of rifle-like effectiveness.
The HK-developed 4.6 x 30mm ammunition provides the penetration approaching that of an assault rifle round and is able to defeat the types of body armor frequently found in the hands of terrorists and criminal gangs, in particular that of the former Soviet Bloc special forces, now the standard NATO test target (CRISAT).
In response to the NATO PDW requirement document D29, HK developed a Personal Defense Weapon system that will penetrate the CRISAT vest, comprised of 1.6mm titanium plates and 20 layers of Kevlar, out to 200 
meters and beyond.
