Pros: Light weight. Cons: Expensive ammo Although I don't own one, I have fired about twenty rounds out of one. They are definetley fun. I could see it working for varmint hunting, and even hme defense in the hands of a capable user. |

A personal defense weapon (often abbreviated PDW) is a compact firearm with increased range and better armor penetrating capabilities than a pistol or submachine gun, while being smaller than a full-sized assault rifle or carbine. * 2.54 kg (5.5 lb), empty Length 500 mm (19.7 in) The MC-10-80 reflex sight, developed by Ring Sights, was designed for the FN P90 and is not compatible with other weapons. It uses a forward-aimed fiber optic collector to illuminate the daytime reticle, which consists of a large circle of about 180 MOA, with a 20-MOA circle surrounding a dot in the center. The night reticle consists of a half-T that is primarily illuminated by a tritium module, which glows red/orange in the dark, and moonlight or ambient light drawn in by an upward-facing collector. The half-T reticle can be seen in the daytime when a strong light source is shined into the rear fiber optic collector. The day sight will tend to wash out on bright surfaces such as white walls, snow, and the sky. The night sight requires total darkness and several moments for the shooter's eyes to adjust to the darkness if moving from a bright environment. Essentially, the operator will lose all sight function by moving from outdoors into a dark house. NO GUNS, NO GLORY!!! |

Type: Carbine 3.4 kg (7.5 lb) loaded, 50 rounds Length :667 mm (26.2 in) -------------------------------------------------------------------------------- Cartridge :5.7 × 28 mm The gun is a semi-automatic sporter version of the FN P90 submachine gun, designed for the U.S. civilian market. It is a blowback-operated firearm, firing from a closed breech, with a semi-automatic firing mode. It features an ambidextrous safety selector and cocking handle, along with downward ejection of spent cases. The PS90 is built in a unique bullpup configuration that places the 50-round translucent magazine above the weapon, parallel to the barrel. This design makes the firearm extremely compact and maneuverable and the translucent magazine makes it easy to quickly check the number of rounds left. The PS90 is constructed largely out of weight-saving polymers. The PS90 has a 16-inch barrel, either an olive drab green or black plastic body (Black PS90s are now in full production) and a MC-10-80 reflex sight identical to that on the standard P90. The MC-10-80 must be removed and replaced by the FN USG M1913 Picatinny rail in order to use aftermarket optics. The USG black reticle MC-10-80 is also available for the PS90 and P90. The barrel rifling has 8 grooves, a 1/9 right-hand twist, with a rifled length of 14.8 inches and a full length of 16.1 inches due to the addition of a fixed "birdcage" flash suppressor. The overall length of the PS90 is 26.3 inches. The trigger pull is approximately 8 lbf. According to the manual, the trigger pull should be between 25 and 45 N (5.6-10.1 lbf). The cast aluminum receiver assembly is drilled and tapped to accept side Picatinny rails on either side of the main optic for laser or light units. The FN PS90 accepts standard P90 50-round box magazines, but ships with a 10 or 30-round magazine depending on state laws. The circular ramp at the bottom of each magazine re-aligns each round ninety degrees to feed into the chamber. The hammer group resembles the one found in the Steyr AUG and FN F2000. It is comprised primarily of polymers including the hammer. The breechblock is part of the "moving parts group,” which contains the twin guide rods, rate of fire stabilizer, recoil buffer, firing pin, and AR-15-style extractor and ejector. The firearm has very low felt recoil. The recoil impulse of 5.7 × 28 mm is approximately one half of 5.56 x 45 mm NATO, while the unique moving parts group further reduces felt recoil through the use of twin recoil springs and the recoil buffer. The felt recoil of the PS90 is comparable to that of a heavy target AR-15 firing .223 Remington. Upon firing the PS90, the barrel itself recoils rearward for about 0.030 of an inch (0.76 mm), enabling the pressure in the barrel to drop to a safe level. The chamber pressure is rated at 50,000 psi for 5.7 × 28 mm FN. Field stripping the PS90 can be done in less than 10 seconds without any tools, breaking it apart into 4 major groups: barrel support/optical sight group, moving parts group, hammer group and the frame/trigger group. If the operator stores the P90 magazines in a regular magazine pouch, the cartridges can fall out if the magazine is bumped from the bottom. The special FN Herstal P90 magazine pouches have a plastic dust cap that encloses the round part of the magazine. This dust cap can help prevent the cartridges from falling out during high impact maneuvers. However, contrary to popular belief, the magazines are not prone to internal cartridge jams. |
