The FN Five-seven, trademarked as the Five-seveN, is a semi-automatic pistol designed and manufactured by FN Herstal in Belgium. The pistol is named for its 5.7-mm (.224 in) bullet diameter, and the trademark capitalization style is intended to emphasize the manufacturer's initials—FN.
The Five-seven pistol was developed in conjunction with the FN P90 personal defense weapon and the FN 5.7×28mm cartridge. The P90 was introduced in 1990, and the Five-seven was introduced in 1998 as a pistol using the same 5.7×28mm ammunition. Developed as a companion pistol to the P90, the Five-seven shares many of its design features: it is a lightweight polymer-based weapon with a large magazine capacity, ambidextrous controls, low recoil, and the ability to penetrate body armor when using certain cartridge types.
Sales of the Five-seven were originally restricted by FN to military and law enforcement customers, but since 2004, the pistol has also been offered to civilian shooters for personal protection, target shooting, and similar uses. Although offered only with sporting ammunition, the Five-seven's introduction to civilian shooters was met with vocal opposition from gun control organizations such as the Brady Campaign, and the pistol has been subject to ongoing controversy in the United States.
The Five-seven is currently in service with military and police forces in over 40 nations, such as Canada, France, Greece, India, Poland, Spain, and the United States. In the United States, the Five-seven is in use with numerous law enforcement agencies, including the U.S. Secret Service. In the years since the pistol's introduction to the civilian market in the United States, it has also become increasingly popular with civilian shooters.
The Five-seven pistol and its 5.7×28mm ammunition were developed by FN Herstal in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge and associated pistols and submachine guns. NATO called for two types of weapons chambered for a new cartridge—one a shoulder-fired weapon, and the other a handheld weapon. According to NATO, these new weapons, termed personal defense weapons (PDWs), were to provide "personal protection in last-resort situations when the user is directly endangered by the enemy [...]." In 1989, NATO published document D/296, outlining a number of preliminary specifications for these weapons:
- The new cartridge was to have greater range, accuracy, and terminal performance than the 9×19mm cartridge. Additionally, it was to be capable of penetrating certain types of body armor.
- The shoulder-fired personal defense weapon was to weigh less than 3 kg (6.6 lb), with a magazine capacity of at least 20 rounds.
- The handheld personal defense weapon (pistol) was to weigh less than 1 kg (2.2 lb), although a weight of 700 g (1.5 lb) was deemed desirable; it was to have a magazine capacity of no fewer than 20 rounds.
- Both weapons were to be sufficiently compact to be carried hands-free on the user's person at all times, whether in the cab of a vehicle or the cockpit of an aircraft, and were to perform effectively in all environments and weather conditions.
FN Herstal was the first small arms manufacturer to respond to NATO's requirement; FN started by developing a shoulder-fired personal defense weapon, the FN P90, along with a small caliber, high velocity 5.7×28mm cartridge type. The original 5.7×28mm cartridge, called the SS90, went into production with the P90 in 1990. This cartridge type was discontinued in 1993, and replaced with the 5.7×28mm SS190, which used a heavier and slightly shorter projectile weighing 2.0 g (31 grains). The reduced length of the SS190 projectile allowed it to be used more conveniently in the Five-seven, which was under development at that time.
In 1993, Jean-Louis Gathoye of FN filed a United States patent application for a delayed blowback operating system intended for the Five-seven pistol, and U.S. Patent 5,347,912 ("Elements for decelerating the recoil of the moving parts of a fire arm") was received the following year. In 1995, FN officially announced development of the Five-seven pistol, and a prototype of the pistol was publicly displayed the following year. With some improvements, a double-action only model of the pistol went into production in 1998, and a single-action model called the Five-seven Tactical was then introduced shortly afterward. The Five-seven first entered service in May 2000, when the Cypriot National Guard (Greek: Εθνική Φρουρά) purchased 250 pistols for their special forces group.
NATO evaluation 
In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum cartridge. The tests compared the relative merits of the FN 5.7×28mm cartridge and the HK 4.6×30mm cartridge, which was created by German small arms manufacturer Heckler & Koch as a competitor to the 5.7×28mm. The results of the NATO tests were analyzed by a group formed of experts from Canada, France, the United Kingdom, and the United States, and the group's conclusion was that the 5.7×28mm was "undoubtedly" the more efficient cartridge.
However, the German delegation and others rejected the NATO recommendation that 5.7×28mm be standardized, halting the standardization process indefinitely. As a result, both the 4.6×30mm and 5.7×28mm cartridges (and the associated weapons) have been independently adopted by various NATO countries, according to preference; the Five-seven pistol is currently in service with military and police forces in over 40 nations throughout the world.
Historically, sales of the Five-seven pistol were restricted by FN to military and law enforcement customers, but in 2004 the new Five-seven IOM model was introduced and offered to civilian shooters for use with 5.7×28mm sporting ammunition. The IOM model incorporated several modifications to the weapon's design, such as the addition of an M1913 accessory rail, a magazine safety mechanism, and fully adjustable sights. Although offered only with sporting ammunition, the Five-seven's introduction to civilian shooters was met with strong opposition from gun control organizations such as the Brady Campaign.
Further development of the Five-seven pistol led to the introduction of the Five-seven USG model, which was approved by the ATF as a sporting firearm in 2004. The USG model incorporates a conventionally shaped square trigger guard, a reversible magazine release, and other minor changes. It is the current Five-seven pistol offered by FN Herstal, but different frame finishes and sight options have also been made available.
The Five-seven is a semi-automatic delayed blowback pistol chambered for FN's 5.7×28mm ammunition. The pistol appears hammerless, but it has a concealed hammer. Polymer materials are used extensively in the pistol's design, and even the steel slide is encased in a polymer shell. In addition to providing reduced weight and greater resistance to corrosion, this also prevents unwanted light reflection. The slide's polymer shell gives the pistol the appearance of being constructed entirely of polymers, but the slide interior, barrel, trigger, springs, pins, and similar parts are all steel. However, the pistol is unusually lightweight, weighing only 744 g (1.6 lb) with a loaded 20-round magazine.
The Five-seven is a full-size pistol, having an overall length of 208 mm (8.2 in), a height of 137 mm (5.4 in), and a max width of 36 mm (1.4 in). It has the same grip angle as the distinguished Browning Hi-Power and M1911 pistols. Despite the considerable length of the pistol's 5.7×28mm ammunition, the grip is not particularly unwieldy—the distance from the trigger to the back of the grip measures 69.85 mm (2.75 in), which is identical to a U.S. Military issue M9 pistol chambered in 9×19mm Parabellum. The Five-seven barrel is cold hammer-forged and chrome-lined, with a total length of 122 mm (4.8 in) and a rifled length of 94 mm (3.7 in). The barrel has eight rifling grooves with a right-hand twist rate of 1:231 mm (1:9.1 in), and it weighs 113 g (0.25 lb). It has a stated service life of 20,000 rounds and the Five-seven is noted for being very accurate.
Current models of the Five-seven are single-action, having a short and light trigger pull of 2 to 3 daN (4.4 to 6.6 lbF). They have a Picatinny rail for mounting accessories, and a magazine safety mechanism that prevents the pistol from firing without a magazine inserted. The grip texture on current pistols is extensively checkered for a superior hold, and each side of the slide has a series of narrow ridges at the rear to aid grasping. The trigger and trigger guard surfaces also have grooves to reduce finger slip, and the trigger guard is elongated to ease firing while wearing gloves. The Five-seven is currently offered in two different frame finishes (standard black or flat dark earth), and two different iron sight systems (adjustable sights or low profile fixed sights).
Particularly significant to the design of the Five-seven pistol is the small caliber, high velocity bottlenecked cartridge it uses. The 5.7×28mm cartridge was created by FN Herstal in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge, which is commonly used in pistols and submachine guns. The 5.7×28mm cartridge weighs 6.0 g (93 grains)—roughly half as much as a typical 9×19mm cartridge—making extra ammunition less burdensome, or allowing more ammunition to be carried for the same weight. Since the 5.7×28mm cartridge also has a relatively small diameter, an unusually high number of cartridges can be contained in a magazine. The cartridge has a loud report and produces considerable muzzle flash, but it has roughly 30 percent less recoil than the 9×19mm cartridge, improving controllability. Due to its high velocity, the 5.7×28mm also exhibits an exceptionally flat trajectory.
One of the design intents for the standard 5.7×28mm cartridge type, the SS190, was that it have the ability to penetrate Kevlar protective vests—such as the NATO CRISAT vest—that will stop conventional pistol bullets. Fired from the Five-seven, the 5.7×28mm SS190 has a muzzle velocity of roughly 650 m/s (2,130 ft/s) and is capable of penetrating the CRISAT vest at a range of 100 m (109 yd), or 48 layers of Kevlar material (roughly equivalent to two stacked Level II Kevlar vest panels) at a range of 50 m (55 yd). It is also capable of penetrating a PASGT vest at a range of 300 m (328 yd) or a PASGT helmet at a range of 240 m (262 yd). FN states an effective range of 50 m (55 yd) and a maximum range of 1,510 m (1,651 yd) for the 5.7×28mm cartridge when fired from the Five-seven pistol.
In testing conducted by Passaic County, New Jersey Sheriff's Department, the 5.7×28mm SS190 penetrated to a depth of 27 cm (11 in) in bare ballistic gelatin, and a depth of 23 cm (9 in) in gelatin protected with a Kevlar vest. In testing, the SS190 and similar 5.7×28mm projectiles consistently turn base over point ("tumble") as they pass through ballistic gelatin and other media, using the 21.6-mm (.85 in) projectile length to create a larger wound cavity. However, some are skeptical of the bullet's terminal performance, and it is a subject of debate among civilian shooters in the United States.
The 5.7×28mm projectile potentially poses less risk of collateral damage than conventional pistol bullets, because the projectile design limits overpenetration, as well as risk of ricochet. The lightweight projectile also poses less risk of collateral damage in the event of a miss, because it loses much of its kinetic energy after traveling only 400 m (437 yd), whereas a conventional pistol bullet such as the 9×19mm retains significant energy beyond 800 m (875 yd). This range exceeds the engagement distances expected for the 5.7×28mm cartridge's intended applications, so the cartridge's limited energy at long range is not conversely considered to be disadvantageous. Since the 5.7×28mm SS190 projectile does not rely on fragmentation or the expansion of a hollow-point bullet, the cartridge and pistol are considered suitable for military use under the Hague Convention of 1899, which prohibits the use of expanding bullets in warfare.
|SS190||SS195LF||SS197SR||EA Protector||EA Varmintor||EA S4|
|Projectile weight||2.0 g (31 gr)||1.8 g (28 gr)||2.6 g (40 gr)||2.6 g (40 gr)||2.3 g (36 gr)||1.8 g (28 gr)|

The Five-seven pistol feeds from detachable box magazines, but it is unconventional in that it feeds cartridges into the chamber without the use of a barrel feed ramp, having a beveled chamber only—the pistol's feeding is inherently reliable because of its use of bottlenecked cartridges. The pistol is supplied with 20-round magazines as standard, or 10-round magazines for jurisdictions where magazines are restricted by law to a maximum capacity of 10 rounds. The Five-seven will also accept an aftermarket extended 30-round magazine, which protrudes an additional 38 mm (1.5 in) from the base of the pistol. With an additional cartridge in the chamber, the Five-seven pistol has a total capacity of 11, 21, or 31 rounds depending on what magazine type is used. Magazine pouches for the Five-seven magazine are available from various manufacturers.
The Five-seven's magazine can be disassembled for cleaning or lubrication by removing the polymer floorplate. The magazine body is constructed of polymer, with steel inserts at the feed lips. Unlike a conventional pistol magazine, it feeds from dual feed lips, with a follower that has the same appearance as that of an M16 rifle's magazine, and which is loaded in the same manner: by pushing cartridges straight down into the magazine, rather than pushing them down and back. This setup makes it very easy to load individual cartridges into the magazine. The magazine floorplate has a slight finger spur, and four holes in the left side of the magazine body allow a convenient estimate of the amount of remaining ammunition.
All controls (excluding the trigger) on the Five-seven USG and earlier models are grey polymer, in contrast to the black polymer frame and slide cover. Similarly, all of the controls on the Five-seven FDE and Five-seven ODG models are black polymer, in contrast to the flat dark earth and olive drab polymer frames. A takedown lever is located at the front on the left side of the weapon's frame, and a slide release is located at the rear on the left side of the frame; these controls are protected from accidental movements by slight projections in the frame contour. A chamber indicator, in the form of a pin inside a tiny hole, is provided on the left side of the slide. When a round has been chambered, this pin will protrude 1.6 mm (0.06 in), which is sufficient to provide both visible and tactile indication of the chamber's status.
Current models of the Five-seven have an ambidextrous manual safety device, which is located in an unconventional position: one control is found on each side of the frame above the trigger guard, where it is reachable with the trigger finger or support hand thumb. A red dot is visible here when the safety is deactivated and the pistol is ready to fire; when the safety is moved to the raised position, it is activated and the red dot is no longer visible. The Five-seven's push-button magazine release, located on the left side of the frame where the trigger guard intersects with the grip, is square-shaped and reversible for left-handed shooters.
The Five-seven can be disassembled quickly and easily, by using the left hand to retract and hold the slide 5 mm (0.25 in) rearwards, while simultaneously using the left-hand thumb to push and hold the takedown lever rearwards. When the slide is released, it moves forward freely and the complete slide assembly can be disengaged from the frame, whereupon the barrel (and captured recoil spring) can be removed from the slide. This level of disassembly is sufficient to perform thorough cleaning of the pistol, and FNH USA recommends no further disassembly except by an authorized armorer, FN Herstal, or FNH USA. Reassembly of the pistol is done in the reverse order, except no use of the disassembly lever is necessary.
Sights and accessories 
The Five-seven has a sight radius of 178 mm (7 in); the pistol is currently offered with either adjustable sights or fixed sights. The "three-dot" type adjustable sights consist of a 2.9-mm (0.12 in) square notch rear and a 3.6-mm (0.14 in) blade front, which has a height of 9.2 mm (0.36 in). The sights are targeted at 91.4 m (100 yd), but can be adjusted for either windage or elevation. The "three-dot" type C-More fixed sights, which are offered as a low profile alternative to the adjustable sights, can only be adjusted for windage. The fixed sights are targeted at 7.6 m (25 ft) using SS195LF ammunition, and are available with or without tritium-illuminated inserts ("night sights") to aid use of the pistol in dim lighting.
The Five-seven is supplied with a lockable hard case, a locking device and keys, a magazine release reversal tool, a sight adjustment tool (not included with the fixed sights model), a cleaning kit, an owner's manual, and three 20-round magazines (or three 10-round magazines, where restricted by law).
The Five-seven can be used in conjunction with a wide range of firearm accessories; holsters are offered by various manufacturers, and the pistol's MIL-STD-1913 (Picatinny) accessory rail will accept tactical lights or laser aiming devices. With the use of an extended, threaded barrel, the pistol can also be fitted with various sound suppressors developed by Advanced Armament Corporation, Gemtech, Silencerco, and other manufacturers. The Gemtech SFN-57, which was developed in 1998 specifically for use with the Five-seven, is a matte black aluminum suppressor with a length of 147 mm (5.8 in), a diameter of 32 mm (1.25 in), and a weight of 147 g (0.33 lb). Israeli manufacturer FAB Defense offers a complete PDW conversion kit for the Five-seven, designated the KPOS G2 FN 5.7, that allows the pistol to be reconfigured into a shoulder-fired personal defense weapon, and CornerShot offers a weapon system compatible with the Five-seven that allows the shooter to aim and fire around corners without being exposed.
- The original Five-seven was introduced in 1998, and it is now discontinued. It had no manual safety device and it was double-action only, with a heavy trigger pull of 4.5 to 6.5 daN (10 to 14 lbF); its double-action only trigger was harshly criticized. The original Five-seven had a pebbled grip pattern, a smoothly contoured accessory rail, low profile fixed sights and a large circular-shaped trigger guard designed to facilitate gloved use. It did not have a slide release and the slide was not serrated as on newer models, but a portion at the rear of the slide was instead slightly concave to aid grasping. The pistol also had slightly different markings, with an FN logo placed on the left side of the frame above the trigger guard.
- Five-seven Tactical
- The Five-seven Tactical was introduced shortly after the original double-action only model, as a single-action alternative. It had a short and light trigger pull of 2 to 3 daN (4.4 to 6.6 lbF), as on current models. It also had the addition of an ambidextrous manual safety device (located on each side of the frame, as on current models), and a slide release. Aside from these modifications, the Tactical model was identical to the original double-action only Five-seven. It was discontinued following the introduction of the IOM model.
- Five-seven IOM
- The Five-seven IOM (Individual Officer Model) was the first model of the Five-seven pistol to be offered to civilian shooters, debuting in 2004. It is now discontinued in favor of the USG model. The IOM was similar in its basic design to the Tactical version, but differed in that it had a MIL-STD-1913 (Picatinny) accessory rail, a serrated slide and trigger guard, and fully adjustable sights. It also had a magazine safety mechanism incorporated into the design, to prevent the pistol from being fired without a magazine inserted.
- Five-seven ODG
- The Five-seven ODG (Olive Drab Green) model was built to the same specifications as the current Five-seven USG model, but it had an olive drab frame finish and black controls, as opposed to the standard black frame finish and grey controls of the Five-seven USG. Like the USG model, the ODG model was offered with either adjustable sights or low profile fixed sights. Since 2012, the ODG model is no longer listed by FNH USA.
Current models 
- Five-seven USG
- The Five-seven USG (United States Government) is currently the standard version of the Five-seven pistol offered by FN Herstal. This model was approved by the ATF as a sporting firearm in 2004, replacing the IOM model. The USG retains the changes that were incorporated in the IOM, but it has further modifications, including a conventionally shaped square trigger guard, a tightly checkered grip pattern, and a larger, reversible magazine release. It was originally offered with adjustable sights, but since 2009 it has also been offered with low profile fixed sights. The USG model has a black frame finish with grey controls as standard, but it has also been offered in limited quantities with black controls.
- Five-seven FDE
- The Five-seven FDE (Flat Dark Earth) model is built to the same specifications as the Five-seven USG, but it has a brown frame finish and black controls, as opposed to the standard black frame finish and grey controls of the Five-seven USG. Like the USG model, the FDE is offered with either adjustable sights or low profile fixed sights.
- Five-seven MK2
- The Five-seven MK2 model was introduced in 2013, and is now featured on FN Herstal's official website. This new model has cocking serrations on the front of the slide as well as on the rear. It has been reported to have a one-piece metal slide (under the polymer cover), whereas the previous models have a two-piece welded metal slide. There is apparently still a choice of fixed or adjustable sights: the model shown on FNH's site is a fixed-sight version; a model with adjustable sights was photographed at the 2013 SHOT show. The rear sight on the adjustable-sight version has also been changed, with beefed-up construction and white straight-edge sight references compared to the present three-dot target-style sights; these have been described as "combat adjustable sights".
- The MK2 as shown has a black frame and slide, with flat black controls in place of the grey controls of the IOM and USG models. FNH is not currently stating on their site whether this model will be produced in any other colors.
The Five-seven pistol and 5.7×28mm ammunition were originally restricted by FN to military and law enforcement customers, but in 2004 the new Five-seven IOM model was introduced, and offered to civilian shooters for use with 5.7×28mm SS192 ammunition. FNH USA has marketed the Five-seven to civilian shooters as a pistol suitable for personal protection, target shooting, and similar uses, but the Five-seven's introduction to civilian shooters was strongly opposed by U.S. gun control organizations such as the Brady Campaign; by the end of 2004, sales of the Five-seven pistol had increased dramatically.
In early 2005, the pistol was subject to controversy in the United States after the Brady Campaign stated that commercially available 5.7×28mm SS192 ammunition penetrated a Level IIA Kevlar vest in testing. The National Rifle Association (NRA) shortly countered the Brady Campaign's claim by stating that the gun control group may not have adhered to standard testing procedures, and that FN only offers armor-piercing varieties of the 5.7×28mm cartridge to military and law enforcement customers. Varieties offered to civilians are classified by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as not armor-piercing, and it was stated that the SS192 and SS196 cartridge variations were unable to penetrate various types of Kevlar vests in tests conducted by FNH USA.
Michael D. Barnes, then-president of the Brady Campaign, responded to the NRA's statements on the Five-seven by challenging NRA Executive Vice President Wayne LaPierre to be shot with the pistol while wearing a Kevlar vest. The NRA again attacked the Brady Campaign's statements, saying that "Barnes demonstrated his group's complete and utter disregard for gun safety and its flaming zeal to further restrict the rights of law-abiding gun owners." In the same year, two pieces of legislation were introduced in the United States Congress, specifically targeting the Five-seven pistol and 5.7×28mm ammunition for a federal ban: the H.R. 1136: PLEA Act was introduced in the House of Representatives by Rep. Eliot Engel (D-NY), and the S. 527: PLEA Act was introduced in the Senate by Sen. Frank Lautenberg (D-NJ); neither bill proceeded to a vote by the House or Senate.
In March 2007, legislation was again introduced in the United States Congress by Rep. Engel, under the new designation H.R. 1784: PLEA Act. Once again, the bill failed to proceed to a vote. In the following years, the Five-seven was subject to further controversy due to reports of the pistol's use by drug cartels in the Mexican Drug War. In the United States, the Five-seven has never been used to kill a police officer, but various news sources such as The Boston Globe and La Jornada reported incidents in which the pistol was used to shoot and kill police officers or civilians in Mexico. According to the ATF, the Five-seven is one of the weapons favored by drug cartels in the Mexican Drug War, and a smuggled Five-seven pistol can sell for up to 66,000 pesos (US$5,000) in Mexico. From Mexico, the pistols have been smuggled into other South American countries; in a July 2010 drive-by shooting in Envigado, Colombia, two cartel gunmen armed with Five-seven pistols opened fire on a group of bystanders outside a nightclub, leaving 9 people dead and 10 wounded.
In November 2009, the Five-seven again became subject to intense controversy in the United States, following the shooting at Fort Hood military base, in Texas. A U.S. Army psychiatrist, Major Nidal Malik Hasan, opened fire on fellow soldiers with a Five-seven pistol, killing 13 people and wounding 29 in the worst shooting ever to take place on an American military base. Shortly after the shooting, FNH USA responded with a fact sheet dismissing allegations about the nature of the pistol, pointing out that it is only offered to civilians with sporting ammunition. Later in the month, a number of gun control organizations such as the Brady Campaign wrote a collaborative letter to U.S. President Barack Obama, citing the weapon's use by the Fort Hood shooter and Mexican drug cartels, and calling on him to ban importation of the Five-seven pistol and 5.7×28mm ammunition. In July 2010, legislation was introduced in the United States Congress by Rep. Engel, for a third time, under the new designation H.R. 6030: PLEA Act. Like its previous incarnations, the H.R. 6030 bill failed to proceed to a vote by either the House of Representatives or Senate.
The first military organization to adopt the Five-seven was the Cypriot National Guard (Greek: Εθνική Φρουρά), which purchased 250 pistols in May 2000 for its special forces group. By 2009, the Five-seven was in service with military and police forces in over 40 nations throughout the world. In 2009, the Military of Libya purchased 367 Five-seven pistols from FN Herstal, along with various other FN weapons, in a controversial sale valued at 11.5 million euros (US$15.8 million). In 2011, these weapons were used by Muammar Gaddafi's military forces in the 2011 Libyan civil war, and Libyan rebel forces were also photographed using captured examples in the war.
In the United States, the Five-seven is currently used by over 300 law enforcement agencies, including the U.S. Secret Service. Military and law enforcement organizations using the Five-seven include:
