Basic Information
The weapon is essentially a modified MP5, designed specifically to use subsonic 149 grain (9.7 gram) ammunition with an integrated suppressor and muzzle break, and capable of having a grenade launcher attached, specifically the M203. Traveling at 330 m/s, the pistol cartridges are subsonic, that is below the supersonic level that creates a supersonic crack, which keeps the weapon unusually quite. The weapon's muzzle flash is also contained within the suppressor, which helps absorb the resulting gunpowder and expanding gases which typically result in most of the noises of the cartridge.
