FN's Five-seveN® PistolThe First of a New Generation
In 1935, the FN-made Browning Hi Power was revolutionary. The market quickly adopted this high-capacity 9mm pistol accordingly, and it has since been fielded by over 100 countries.
FN's newest contribution the handgun's evolution is named the Five-seveN®. This 20-round pistol fires a 5.7mm bullet that will defeat most body armor in military service around the world today. Essentially, the Five-seveN® represents a quantum leap forward in the handgun's suitablity for close engagements by delivering the type of performance that was previously confined to rifles or carbines. Elements of this performance include:
High magazine capacity: The Five-seveN® comes standard with 20-round magazine.
High stopping power: The Five-seveN® fires the 5.7x28mm SS190 Ball round which reliably penetrates Kevlar helmets and vests as well as CRISAT protection.
High hit probability: The Five-seveN's® extremely low recoil impulse results in virtually no muzzle climb, thereby facilitating fast and controllable follow-up shots.
Yet, the Five-seveN® is:
Light and ergonomic: Weighing 30% less than most 9mm pistols, the smoothly-contoured Five-seveN® is comfortable to carry and quick to deploy.
Fully safe: Due to its double-action firing mechanism, the Five-seveN® offers no inherent risk of accidental discharge during transportation. Furthermore, all of its safety devices are automatically reengaged following each firing cycle.
The Five-seveN® fires the SS190 5.7x28mm ball round. This projectile will perforate any individual protection on today's battlefield including the PASGT kevlar helmet, 48 layers of kevlar body armor and the CRISAT target (titanium and kevlar). The SS190's conventional design allows it to be manufactured on existing production lines, and its lead-free composition eliminates range contamination.

SS190 The SS190 is the 5.7x28 mm Ball round. Its projectile will perforate any individual protection on today's battlefield including the PASGT kevlar helmet, 48 layers of kevlar body armor and the CRISAT target (titanium and kevlar). The SS190's conventional design allows it to be manufactured on existing production lines, and its lead-free composition eliminates range contamination.
Caliber	5.7x28mm
Cartridge length	1.6 in. (40.5mm)
Projectile weight	˜ 2.02g
Recoil implulse	˜ 1.95 kg m/s
Chamber pressure	345 MPa
Muzzle velocity	715 m/s
Perforation at 200 m	- Body armor (48 layers of kevlar) - PASGT helmet

Sb193 (subsonic round) The Sb193 cartridge has been designed to deliver a muzzle velocity of about 300 meters per second. This eliminates the loud crack caused by a bullet travelling faster than the speed sound. To enable the weapon to function reliably when firing this ammunition, the reduced velocity is compensated for by using a heavier bullet. The subsonic round is identified by the bullet's white tip.
Cartridge length	1.6 in. (40.5mm)
Projectile weight	˜ 3.6g
Recoil implulse	˜ 1.3 kg m/s
Chamber pressure	345 MPa
Muzzle velocity	300 m/s
Energy loss a 50 m	˜ 100 J
Effective range (penetration of 24 layers of kevlar)	50 m

FN P90 Laser Target Designator

P90 submachine gun with integrated laser target designator The FN HERSTAL P90 submachine gun can be supplied with an integrated laser on request. This laser is fully integrated into the receiver without modifying the the weapon's outer shape, balance and ergonomics. The customer can choose either a visible "red dot" laser or an infra-red laser for use in conjunction with night vision equipment. P90 LV (with visible laser) In low light conditions and indoors the laser designator, when activated by a pressure switch, projects a highly visible red dot onto the target. The laser designator can be zeroed so that rounds hit exactly at the point indicated by the laser. This enables the user to aim accurately without shouldering the weapon; he or she can fire from the waist, the chest or with the weapon held away from the body. The laser designator allows very rapid target acquisition, especially at close range and/or in low light. The laser dot also has a theoretically disuasive effect on the enemy who can see that a weapon is precisely aimed at them. The laser system has an adjustment switch which allows the user to select one of the laser's three settings: off to avoid accidental activation low intensity for extend battery life or increased eye safety during training hight intensity for maximum combat visibility The visible laser designator allows the user to practice rapid target acquisition and instinctive shooting without firing, as the dot indicates the point of impact. P90 LIR (with infra red laser) The infra red wavelength laser designator projects a dot onto the target that is not visible to the naked eye. The user - and the target - must have night vision equipment to see the dot. This type of designator is designed for night use and for operations where maximum discretion is required (anti-terrorist, hostage rescue, covert operations).
