The Five-seveN pistol was designed by FN company (Belgium) as a complimentary sidearm for the P90 submachine-gun. The P90 and Five-seveN share the same ammunition, the 5.7x28mm SS190 cartridge. The SS190 ammunition looks like scaled down 5.56mm NATO round and boosts the 2.02 gramm (31 grains) pointed steel and alluminium core bullet to the muzzle velocity of 650 meters per second (ca. 2130 fps) from the pistol barrel. The key idea behind that ammunition and weapons is to provide good penetration against personnel, protected by modern body armour, while keeping weapons' weight, dimensions and recoil at the reasonable levels.
The Five-seveN is a delayed blowback operated, semi-automatic firearm. It featured polymer frame with underbarrel acessory rail. The gun is available in two versions: Five-seveN standard, intended mostly for military users, and Five-seveN Tactical, intended mostly for Law Enforcement users who carry handguns as a primary weapons. The only difference between Standart and Tactical models is in the trigger type: the Five-seveN standard features Double Action Only trigger with long trigger pull and no external safeties; The Five-seveN Tactical featured Single Action trigger with short and light trigger pull and ambidextrous safety switch, located on the frame above the trigger. Both variants are striker fired, with internal firing pin safety. The sights are fixed, with optional night sights (with luminous dots inserts) available.
The Five-seveN is advertised as being capable to penetrate standart PAGST vest at 300 meters and standart CRISAT (kevlar + titanium) vest at 100 meters.
The Five-seveN is available from FN for government or law enforcement sales only.
