[[File:FN Five-seveN FDE right side.jpg|thumb|FN Five-seven (FDE) Flat Dark Earth]]

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.<ref name="gourley2003">Gourley, S.; Kemp, I (November 26, 2003). "The Duellists". Jane's Defence Weekly ({{ISSN|0265-3818}}), Volume 40 Issue 21, pp 26–28.</ref> NATO called for two types of weapons chambered for a new cartridge—one a shoulder-fired weapon, and the other a handheld weapon.<ref name="gourley2003"/> According to NATO, these new weapons, termed [[personal defense weapon]]s (PDWs), were to provide "personal protection in last-resort situations when the user is directly endangered by the enemy [...]."<ref name="gourley2003"/> 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 ballistics|terminal performance]] than the 9×19mm cartridge.<ref name="gourley2003"/> Additionally, it was to be capable of penetrating certain types of [[body armor]].<ref name="gourley2003"/>
* The shoulder-fired personal defense weapon was to weigh less than 3&nbsp;kg (6.6&nbsp;[[pound (mass)|lb]]), with a [[magazine (firearms)|magazine]] capacity of at least 20 rounds.<ref name="gourley2003"/>
* The handheld personal defense weapon (pistol) was to weigh less than {{convert|1|kg|lb|abbr=on}}, although a weight of {{convert|700|g|lb|abbr=on}} was deemed desirable; it was to have a magazine capacity of no fewer than 20 rounds.<ref name="gourley2003"/>
* 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.<ref name="gourley2003"/>

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.<ref name="gourley2003"/> The original 5.7×28mm cartridge, called the ''SS90'', went into production with the P90 in 1990.<ref name="marchington2004">{{cite book |first=James |last=Marchington |year=2004 |title=The Encyclopedia of Handheld Weapons |publisher=Lewis International, Inc. |location=Miami |isbn=978-1-930983-14-4}}</ref> 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&nbsp;[[Grain (unit)|grains]]).<ref name="gunzonetimeline1990">{{cite web |url=http://www.thegunzone.com/556dw-10.html |title=The 5.56 × 45mm Timeline: 1990–1994 |author=Watters, Daniel E. |publisher=The Gun Zone |access-date=January 31, 2010 |url-status=dead |archive-url=https://web.archive.org/web/20100104174808/http://thegunzone.com/556dw-10.html |archive-date=January 4, 2010 }}</ref><ref name="marchington2004"/> 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.<ref name="gunzonetimeline1990"/>

In 1993, Jean-Louis Gathoye of FN filed a United States [[patent application]] for a [[Blowback (arms)#Delayed blowback|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 firearm") was received the following year.<ref name="gunzonetimeline1990"/><ref>{{cite web |url=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=5347912.PN.&OS=PN/5347912&RS=PN/5347912 |title=U.S. Patent 5,347,912 (Elements for decelerating the recoil of the moving parts of a firearm) |publisher=[[United States Patent and Trademark Office]] |access-date=July 15, 2010 |archive-url=https://web.archive.org/web/20170202002155/http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=5347912.PN.&OS=PN%2F5347912&RS=PN%2F5347912 |archive-date=February 2, 2017 |url-status=live }}</ref> In 1995, FN officially announced development of the Five-seven pistol, and a prototype of the pistol was publicly displayed the following year.<ref name="gunzonetimeline1995">{{cite web |url=http://www.thegunzone.com/556dw-11.html |title=The 5.56 × 45mm Timeline: 1995–1999 |author=Watters, Daniel E. |publisher=The Gun Zone |access-date=January 31, 2010 |archive-url=https://web.archive.org/web/20100104174826/http://thegunzone.com/556dw-11.html |archive-date=January 4, 2010 |url-status=dead }}</ref> With some improvements, a [[Trigger (firearms)#Double-action only|double-action only]] model of the pistol went into production in 1998, and a [[Trigger (firearms)#Single-action|single-action]] model called the ''Five-seven Tactical'' was then introduced shortly afterward.<ref name="hogg2002"/><ref name="fnmfg57tactical">{{cite web|url=http://www.fnmfg.com/lawenf/tactical/tactical.htm |title=Five-seveN Tactical Pistol |year=2000 |publisher=[[FN Manufacturing LLC]] |access-date=April 22, 2010 |archive-url=https://web.archive.org/web/20000919084555/http://www.fnmfg.com/lawenf/tactical/tactical.htm |archive-date=September 19, 2000 |url-status=dead }}</ref> The Five-seven first entered service in May 2000, when the [[Cypriot National Guard]] ({{langx|el|Εθνική Φρουρά}}) purchased 250 pistols for their special forces group.<ref name="gourley2003"/>

=== NATO evaluation ===

In 2002 and 2003, [[NATO]] conducted a series of tests with the intention of standardizing a [[Personal defense weapon|PDW]] cartridge as a replacement for the [[9×19mm Parabellum]] cartridge.<ref name="oliver2007">{{cite web|url=http://www.global-defence.com/2006/Utilities/article.php?id=40 |title=In the Line of Fire |author=Oliver, David |year=2007 |publisher=Global Defence Review |access-date=October 19, 2009 |archive-url=https://web.archive.org/web/20061016074936/http://www.global-defence.com/2006/Utilities/article.php?id=40 |archive-date=October 16, 2006 |url-status=dead }}</ref> 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.<ref name="oliver2007"/> 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.<ref name="oliver2007"/>

At the time, the German delegation and others rejected the NATO recommendation that 5.7×28mm should be standardized, delaying the standardization until its eventual completion in February 2021.<ref>{{cite web |last1=Sagi |first1=Guy J |title=NATO Standardizes FN’s 5.7x28 mm Cartridge |url=https://www.americanrifleman.org/content/nato-standardizes-fn-s-5-7x28-mm-cartridge/ |website=[[American Rifleman]] |publisher=National Rifle Association of America |access-date=16 January 2023 |language=en}}</ref><ref name="gourley2003"/><ref name="oliver2007"/> Despite this delay, 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 (see {{Section link|FN Five-seven|Users}}).<ref name="gourley2003"/><ref name="milrev"/>

=== Present ===
At first, sales of the Five-seven pistol were restricted by [[FN Herstal|FN]] to military and law enforcement customers,<ref name="fnmfgdao"/> but in 2004 the new ''Five-seven IOM'' model was introduced and offered to civilian shooters for use with [[5.7×28mm]] sporting ammunition.<ref name="sterett2005">{{cite web |url=http://www.gunweek.com/2005/feature0110.html |title=FN 5.7mm Five-seveN Pistol Makes Civilian Model Debut |author=Sterett, Larry S. |publisher=Gun Week |year=2005 |access-date=October 19, 2009 |archive-url=https://web.archive.org/web/20121029110313/http://www.gunweek.com/2005/feature0110.html |archive-date=October 29, 2012 |url-status=dead }}</ref> The IOM model incorporated several modifications to the weapon's design, such as the addition of an [[Picatinny rail|M1913]] accessory rail, a [[Safety (firearms)#Magazine disconnects|magazine safety]] mechanism, and fully adjustable sights.<ref name="sterett2005"/>

Further development of the Five-seven pistol led to the introduction of the ''Five-seven USG'' model, which was approved by the [[BATFE|ATF]] as a sporting firearm in 2004.<ref name="fnhusaammo2006">{{cite web|url=http://www.fnhusa.com/contents/tw_57x28mm.htm |title=Responses to Frequently Asked Questions about 5.7×28mm Ammunition and Firearms Systems |year=2006 |publisher=[[FNH USA]] |access-date=February 1, 2010 |archive-url=https://web.archive.org/web/20060411012151/http://www.fnhusa.com/contents/tw_57x28mm.htm |archive-date=April 11, 2006 |url-status=dead }}</ref> The USG model incorporates a conventionally shaped square [[trigger guard]], a reversible [[magazine release]], and other minor changes.<ref name="fnhusa57"/>

The ''Five-seven MK2'' was introduced in 2013, replacing the USG model.<ref name="fnhusa57"/> The MK2 model has cocking serrations on the front of the slide, all black controls, and slightly different iron sights.<ref name="fnhusa57"/>

The ''Five-seven MK3 MRD'' was introduced at [[Eurosatory]] in 2022, introducing the possibility to mount a [[Red dot sight|Mini Red Dot]] on top of the slide, a [[Barrel threads|threaded barrel]], making it possible to use a [[Silencer (firearms)|silencer]], a new texture pattern on the grip and deeper slide serrations.<ref>{{cite web|url=https://www.gunsweek.com/en/pistols/news/new-fn-five-seven-mk3-mrd-semi-automatic-pistol|title=New FN Five-seveN Mk3 MRD semi-automatic pistol|publisher=GUNSweek.com|date=June 9, 2022|accessdate=June 14, 2022}}</ref>

Particularly significant to the design of the Five-seven pistol is the small caliber, high [[muzzle velocity|velocity]] bottlenecked cartridge it uses.<ref name="marchington2004"/> 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.<ref name="oliver2007"/> The 5.7×28mm cartridge weighs 6.0&nbsp;g (93&nbsp;[[grain (unit)|grains]])—significantly lighter than the average [[9×19mm Parabellum]] cartridge (M882 NATO total cartridge weight of 12 grams (180 grains))<ref>{{Cite news|url=http://www.shootingtimes.com/ammo/the-rise-of-the-9mm-luger/|title=The Rise of the 9mm Luger - Shooting Times|date=2013-04-30|newspaper=Shooting Times|language=en-US|access-date=2017-01-06|archive-url=https://web.archive.org/web/20170106102738/http://www.shootingtimes.com/ammo/the-rise-of-the-9mm-luger/|archive-date=2017-01-06|url-status=live}}</ref>—making extra ammunition less burdensome, or allowing more ammunition to be carried for the same weight.<ref name="dettyTL2008"/><ref name="fnhusaammo2002">{{cite web|url=http://www.fnhusa.com/contents/tw_57x28system.htm |title=FNH USA, Inc. 5.7×28mm Weapon System |year=2002 |publisher=[[FNH USA]] |access-date=February 1, 2010 |archive-url=https://web.archive.org/web/20021225101159/http://www.fnhusa.com/contents/tw_57x28system.htm |archive-date=December 25, 2002 |url-status=dead }}</ref><ref name="fortierusg02">{{cite web|url=http://www.handgunsmag.com/ammunition/hg_militarytoday_200811 |title=Military Ammo Today |year=2008 |author=Fortier, David |work=Handguns Magazine |access-date=October 19, 2009 |archive-url=https://web.archive.org/web/20100122045316/http://www.handgunsmag.com/ammunition/hg_militarytoday_200811/ |archive-date=2010-01-22 |url-status=dead }}</ref> Since the 5.7×28mm cartridge also has a relatively small diameter, an unusually high number of cartridges can be contained in a [[magazine (firearms)|magazine]].<ref name="amselle2011">{{cite web |url=http://www.tactical-life.com/online/special-weapons/fn-five-seven-57x28mm |title=FN FIVE-SEVEN 5.7×28mm |date=November 2011 |author=Amselle, Jorge |work=Special Weapons For Military & Police |access-date=November 9, 2011 |archive-url=https://web.archive.org/web/20111224172429/http://www.tactical-life.com/online/special-weapons/fn-five-seven-57x28mm/ |archive-date=December 24, 2011 |url-status=live }}</ref> The cartridge has a loud [[muzzle blast|report]] and produces considerable [[muzzle blast#Muzzle flash|muzzle flash]], but it has roughly 30 percent less [[recoil]] than the 9×19mm cartridge, improving [[muzzle rise|controllability]].<ref name="ayoob01"/><ref name="marchington2004"/><ref name="fortierusg02"/> Due to its high velocity, the 5.7×28mm also exhibits an exceptionally flat [[trajectory]].<ref name="dockery2007"/>

One of the design intents for the standard 5.7×28mm cartridge type, the ''SS190'', was that it would have the ability to penetrate [[Kevlar]] [[ballistic vest|protective vests]]—such as the NATO [[CRISAT]] vest—that will stop conventional pistol bullets.<ref name="fortierusg02"/> Fired from the Five-seven, the 5.7×28mm SS190 has a muzzle velocity of roughly 650 [[Metre per second|m/s]] (2,130 [[ft/s]]) and is capable of penetrating the CRISAT vest at a range of {{convert|100|m|yd|abbr=on}}, or 48 layers of [[Kevlar]] material (roughly equivalent to two stacked [[ballistic vest#Performance standards|Level II]] Kevlar vest panels) at a range of {{convert|50|m|yd|abbr=on}}.<ref name="fnmfg57tactical"/><ref name="fnhusaammo2002"/> It is also capable of penetrating a [[Personnel Armor System for Ground Troops|PASGT]] vest at a range of {{convert|300|m|yd|abbr=on}} or a PASGT helmet at a range of {{convert|240|m|yd|abbr=on}}.<ref name="fnmfg57tactical"/> FN states an effective range of {{convert|50|m|yd|abbr=on}} and a maximum range of {{convert|1510|m|yd|abbr=on}} for the 5.7×28mm cartridge when fired from the Five-seven pistol.<ref name="sterett2005"/>

In testing conducted by [[Passaic County, New Jersey]] Sheriff's Department, the 5.7×28mm SS190 penetrated to a depth of {{convert|27|cm|in|abbr=on}} in bare [[ballistic gelatin]], and a depth of {{convert|23|cm|in|abbr=on}} in gelatin protected with a Kevlar vest.<ref name="humphries2008"/> In testing, the SS190 and similar 5.7×28mm [[projectile]]s consistently turn base over point ("tumble") as they pass through ballistic gelatin and other media, using the 21.6-mm (.85&nbsp;in) projectile length<ref name="sterett2005"/> to create a larger wound cavity.<ref name="dettyTL2008"/><ref name="bahde2009"/><ref name="humphries2008"/> However, some are skeptical of the bullet's [[Terminal ballistics|terminal performance]], and it is a subject of debate among civilian shooters in the United States.<ref name="bahde2009"/>

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]].<ref name="humphries2008"/><ref name="cutshaw2006"/><ref name="57facts">{{cite web |url=http://fnhusa1.com/PDF/5.7_Brochure.pdf |title=Five-seveN Facts |publisher=[[FNH USA]] |date=November 9, 2009 |access-date=September 18, 2010 |archive-url=https://web.archive.org/web/20110711014209/http://fnhusa1.com/PDF/5.7_Brochure.pdf |archive-date=July 11, 2011 |url-status=usurped }}</ref> 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 {{convert|400|m|yd|abbr=on}}, whereas a conventional pistol bullet such as the 9×19mm retains significant energy beyond {{convert|800|m|yd|abbr=on}}.<ref name="dockery2007"/> 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 considered to be disadvantageous.<ref name="dockery2007"/> Since the 5.7×28mm SS190 projectile does not rely on fragmentation or the expansion of a [[hollow point bullet|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.<ref name="bahde2009"/>

The Five-seven pistol feeds from [[Magazine (firearms)|detachable box magazines]], but it is unconventional in that it feeds cartridges into the [[Chamber (firearms)|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.<ref name="jbwood"/> The pistol is supplied with 20-round magazines as standard, or 10-round magazines for jurisdictions with a [[high-capacity magazine ban]].<ref name="ownersmanual2009"/> The Five-seven will also accept an aftermarket extended 30-round magazine, which protrudes an additional {{convert|38|mm|in|abbr=on}} from the base of the pistol.<ref name="amselle2011"/> With an additional cartridge in the chamber, the Five-seven pistol has a total capacity of 11, 21, or 31 rounds depending on which magazine type is used.<ref name="ownersmanual2009"/> Magazine pouches for the Five-seven magazine are available from various manufacturers.{{Citation needed|date=November 2021}}

The Five-seven's magazine can be disassembled for cleaning or lubrication by removing the polymer floorplate.<ref name="ownersmanual2009"/> The magazine body is constructed of polymer, with steel inserts at the feed lips.<ref name="jbwood"/> Unlike a conventional pistol magazine, it is a double-stack staggered-feed magazine, 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.<ref name="wagner2008">{{cite web|url=http://www.gundigest.com/article/FN5.7_PartTwo |title=FN's 5.7 Civilian-Legal Dynamic Duo Gives You the Tactical Edge |author=Wagner, Scott |date=August 19, 2008 |work=Gun Digest |access-date=August 1, 2010 |archive-url=https://web.archive.org/web/20100429100016/http://www.gundigest.com/article/FN5.7_PartTwo |archive-date=2010-04-29 |url-status=dead }}</ref> This setup makes it very easy to load individual cartridges into the magazine.<ref name="jbwood"/> 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.<ref name="ownersmanual2009"/><ref name="sterett2005"/>

=== Controls ===
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.<ref name="grevillius2006"/> 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.<ref name="fnhusa57"/> 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.<ref name="ownersmanual2009"/><ref name="sterett2005"/> A [[loaded chamber indicator|chamber indicator]], in the form of a pin inside a tiny hole, is provided on the left side of the [[pistol slide|slide]].<ref name="ownersmanual2009"/> When a round has been chambered, this pin will protrude {{convert|1.6|mm|in|abbr=on}}, which is sufficient to provide both visible and tactile indication of the chamber's status.<ref name="jbwood"/><ref name="grevillius2006"/>

Current models of the Five-seven have an [[ambidextrous]] manual [[Safety (firearms)|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.<ref name="ownersmanual2009"/><ref name="grevillius2006"/> 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.<ref name="ownersmanual2009"/> The pistol'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.<ref name="ownersmanual2009"/>

The Five-seven can be disassembled quickly and easily, by using the left hand to retract and hold the slide {{convert|5|mm|in|abbr=on}} rearwards, while simultaneously using the left-hand thumb to push and hold the takedown lever rearwards.<ref name="ownersmanual2009"/><ref name="marchington2004"/> 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.<ref name="ownersmanual2009"/> This level of disassembly is sufficient to perform thorough [[Firearm maintenance|cleaning]] of the pistol, and FNH USA recommends no further disassembly except by an authorized armorer, [[FN Herstal]], or FNH USA.<ref name="ownersmanual2009"/> Reassembly of the pistol is done in the reverse order, except no use of the disassembly lever is necessary.<ref name="ownersmanual2009"/>

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.<ref name="sterett2005"/><ref name="fnmfgdao"/> [[FNH USA]] has marketed the Five-seven to civilian shooters as a pistol suitable for [[self-defense|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.<ref name="fnhusa57"/><ref name="brady2005"/><ref name="statesman01">{{cite news|url=http://www.statesman.com/news/content/news/stories/local/2009/11/07/1107gun.html |title=Pistol linked to attack called powerful, concealable – 5.7mm handgun called 'an assault rifle that fits in your pocket.' |author=Ward, Mike |work=[[Austin American-Statesman]] |publisher=[[Gannett]] |date=November 7, 2009 |access-date=November 27, 2010 |archive-url=https://web.archive.org/web/20110427063343/http://www.statesman.com/news/content/news/stories/local/2009/11/07/1107gun.html |archive-date=April 27, 2011 |url-status=dead }}</ref>
