The FN P90 is a Belgian Personal Defence Weapon (PDW) - a selective fully automatic cross between a sub-machine gun and an assaultrifle, compact enough to be carried by support troops such as signals troops, drivers, engineers and the like, but with effective firepower. The FN P90 is chambered for the 5.7 x 28 mm cartridge and is fed by a 50-round box magazine with a rate of fire of 900 rounds-per-minute. Research FN P90
