   The Five Seven pistol was designed by a Belgian Fabrique Nationale (FN) company. Sometimes it is designated as the Five-seveN in order to spell initials of the manufacturer. Numbers in the designation of this pistol (5-7) also indicate an unusual 5.7 mm cartridge. The main goal was to develop a handgun with good penetration against body armor, yet with reasonable dimensions, weight and recoil. This pistol was first publicly revealed in 1996. Originally this pistol was available for military and law enforcement sales only. The Five Seven was first adopted in 2000 by Cypriot National Guard. Eventually it became very popular. Currently the Five Seven is in service with military and law enforcement forces with more than 40 countries, including United States. A civilian version was introduced in 2004.

   This pistol is chambered for newly-developed high-velocity 5.7x28 mm SS190 ammunition. This cartridge was developed by Fabrique Nationale in the late 1980s and was first used on a P90 submachine gun. It resembles a scaled-down standard NATO 5.56 x 45 mm Remington round. The intermediate 5.7x28 mm round is larger than traditional pistol and submachine gun ammunition, but is smaller comparing than assault rifle ammunition. This round has a very high velocity. The 5.7x28 mm bullet travels twice faster than a 9x19 mm Parabellum bullet. It has enhanced penetration comparing with 9x19 mm round due to its high velocity and sharp bullet. At close range it has impressive penetration and is effective against armor vests, helmets and ballistic glass. The FN advertises, that the Five Seven penetrates a standard CRISAT (kevlar + titanium) vest at a range of 100 meters and PAGST vest at a range of 300 meters. Various rounds are available, including standard, tracer, and round with subsonic bullet speed. The Five Seven is the only handgun chambered for this unique cartridge.

   However the cartridge is the only novelty of this pistol. Otherwise it has a traditional design with delayed blowback operation. This weapon has a double-action trigger. So the weapon can be carried with a loaded chamber. There is a version with a single-action only trigger.

   There is an ambidextrous safety switch, mounted above the trigger. It also has internal firing pin safety. Early models of the Five Seven had firing pin safety only with no manual safeties. The pistol can be easily dismantled into 4 main parts.

   A double-stack magazine of the Five Seven holds 20 rounds. Magazine release button can be reversed from left side of the grip to the right.

   The pistol has a simple iron sights. Range of effective fire is up to 100 m.

   The grip can be fitted with backstraps of various sizes. So the pistol can be tailored to fit well in almost every hand. There is an accessory rail under the barrel. It can be used to mount tactical flashlights or laser pointers. This pistol is compatible with a sound suppressor. Once fitted with sound suppressor it has to use special bullets with subsonic speed.
