The P90 is a Belgian designed personal defense weapon. The weapon’s name is an abbreviation of Project 90, which specifies a weapon system of the 1990s. The P90 is considered a Personal Defense Weapon (PDW), and was designed as a compact but powerful firearm for vehicle drivers, operators of crew-served weapons, support personnel, special forces and anti-terrorist units.
Developed between 1986–1987 at Fabrique Nationale de Herstal, the P90 features a compact bullpup design, ambidextrous grip and a polymer and alloy-based construction. The weapon contains several innovative features including the proprietary 5.7x28mm ammunition, designed for greater penetration of body armour than pistol ammunition.
The P90 and variants are in use by military and police forces in over thirty countries worldwide, and sports models are popular among civilian shooters.
The P90 was developed between 1986 and 1987 in Herstal, Belgium. Its goal was to replace the pistol-caliber carbines which were in use at the time by military and law enforcement personnel, as it had become evident that such weapons were ineffective against body armour, even with the longer barrel length compared to handguns.
The gun was designed in conjunction with the new 5.7x28mm cartridge, which has a greater penetrating capability, lethal range and flatter trajectory than most other pistol caliber cartridges such as the NATO-standard 9x19mm Parabellum round. Initially the weapon used a 5.7x28mm SS90 cartridge (with a lightweight, roundnose, jacketed projectile and a polymer core), as well as tracer, training (reduced range), sub-caliber (increased velocity and effective range of up to 250 m) and blank ammunition. The first prototype firing this ammunition was completed in October 1986, and over 3,000 submachine guns were produced in this configuration until 1993 in a low-rate initial production run.
Meanwhile, FN revised the ammunition, with the intention of using it in a planned semi-automatic pistol of the same caliber the Five-seveN. The new cartridge, designated the SS190, has a more conventional full metal, plated steel jacket, lead core and steel/aluminium penetrator. Several other projectiles were also developed for the new cartridge, including the L191 tracer round, a subsonic SB193 bullet for sound-suppressed P90 firearms and blank ammunition. A modified version of the P90 adapted to use the new ammunition was introduced in 1993.
The firearm is produced in several variations. All of these versions are able to mount certain optional accessories such as tactical slings, empty case collector bags, bayonets, visible and infrared laser aiming modules (LAM) and tactical flashlights.
