DESIGN
The P90 was designed in the late 1980’s for two markets. First as a sub machine gun with armor piercing capabilities. A lot of law-enforcement agencies turned from their trusty 9mm MP5 to 5.56mm assault rifles, because nowadays a lot of bad guys use body armor. Assault rifles are far more cumbersome in close quarter situations. A sub machine gun with the same capabilities as an assault rifle was needed. The second reason is that NATO started its Personal Defence Weapon (PDW) program. The PDW program was started to equip non-combat personnel with a weapon that would be easy to fire with one hand, good probability of hit and reasonable lethality. The P90 uses a shortened 5.56mm NATO round, called 5.7x28mm SS190. The 5.7mm has a lower recoil than a 9mm and pierces armor much better. The P90 is fed by an orange or grey 50 round magazine on top of the weapon. Shells are not blown out but pushed out. A handful of shells are always kept in the weapon. When the next round is fired, the oldest shell will be pushed out. The P90 has no iron sights. A reflex sight is standard, but can be replaced by Piccatiny rails, and thus every type of sighting system.

VARIANTS

P90
There is only one version of the P90.

PERFORMANCE
The P90 can be fitted with a wide variety of attachments. Piccatiny rails are used to attach sights, lasers or lights. Reloading the P90 is a bit more difficult than other weapon. The 50 round magazines ensure that reloading is not often needed. Although the P90 is outperformed by the MP-7, the P90 has some advantages: the basic load is 50 rounds, no stock has to be retracted and the P90 is slightly more accurate. The P90 can be fired one handed, but with decreased accuracy. The P90 can be fitted with a special, and rather large, silencer. The P90 can be quite silent if the silencer and subsonic ammunition are used.
