Assault SMG

The Assault SMG is a new SMG in the GTA IV DLC The Ballad of Gay Tony. It is based on the Belgian FN P90, outfitted with a suppressor. The P90 is known as a personal defense weapon, as it features a cartridge size somewhere between a pistol round and an assault rifle round (the P90 uses the proprietary 5.7x28mm cartridge). The Assault SMG is one of the first bullpup weapons offered in the GTA series. It is perfect in gunfights and easy to carry due to its light and compact size. The SMG is also the first weapon that is used by Luis in the mission Dropping In....

Trivia
A bullpup configuration has the action and magazine of the weapon is located behind the trigger to reduce the overall length and weight of the weapon.
