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.
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
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.
