==History==
===Development===
The P90 and its [[FN 5.7×28mm|5.7×28mm]] ammunition were developed by the Belgian company 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 [[Chamber (firearms)|chambered]] for a new cartridge—one a [[Shoulder-fired missile|shoulder-fired weapon]], and the other a handheld weapon.<ref name="gourley2003"/> 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 [...]."<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 [[ballistic trauma|terminal performance]] than the 9×19mm cartridge.<ref name="gourley2003"/> Additionally, it was to be capable of penetrating [[body armor]].<ref name="gourley2003"/>
* The shoulder-fired personal defense weapon was to weigh less than {{convert|3|kg|lb|abbr=on}}, 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 at least 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 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=9781930983144}}</ref> The SS90 propelled a 1.5&nbsp;g (23&nbsp;[[grain (unit)|grain]]) plastic-core [[projectile]] from the P90 at a [[muzzle velocity]] of roughly {{convert|850|m/s|ft/s|}}.<ref name="marchington2004"/>

Following the P90's introduction, FN revised the 5.7×28mm ammunition.<ref name="gunzonetimeline1990"/> The new variation, designated the ''SS190'', used a projectile {{convert|2.7|mm|in|abbr=on}} shorter in length than that of the SS90.<ref name="marchington2004"/> This allowed it to be used more conveniently in the 5.7×28mm [[FN Five-seven]] pistol, which was under development at that time.<ref name="gunzonetimeline1990"/> The SS190 projectile had a greater weight, and a more conventional construction with an aluminium and steel core.<ref name="gunzonetimeline1990"/><ref name="marchington2004"/> The first prototypes of the SS190 were created in 1992, and the design was finalized in 1993, replacing the SS90.<ref name="gunzonetimeline1990"/> A modified version of the P90, with a magazine adapted to use the shortened ammunition, was then introduced in the same year.<ref name="gunzonetimeline1990"/> Several special cartridge variations were developed, such as the L191 [[tracer ammunition|tracer]] round and the SB193 [[speed of sound|subsonic]] round for use with a sound-suppressed P90.<ref name="jones2009">{{cite book |editor1-first=Richard D. |editor1-last=Jones |editor2-first=Leland S. |editor2-last=Ness |title=Jane's Infantry Weapons 2009/2010 |date=January 27, 2009 |edition=35th |publisher=Jane's Information Group |location=Coulsdon |isbn=9780710628695}}</ref>

===NATO evolution===
{{further|FN 5.7×28mm#History}}

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.<ref name="oliver2007">{{cite web|author=Oliver, David|year=2007|title=In the Line of Fire|url=http://www.global-defence.com/2006/Utilities/article.php?id=40|archive-url=https://web.archive.org/web/20061016074936/http://www.global-defence.com/2006/Utilities/article.php?id=40|archive-date=October 16, 2006|access-date=October 19, 2009|publisher=Global Defence Review}}</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 [[Germany|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"/> However, the German delegation and others rejected the NATO recommendation that 5.7×28mm be standardized, halting the standardization process indefinitely.<ref name="oliver2007"/><ref name="gourley2003"/> 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 P90 is currently in service with military and police forces in over 40 countries.<ref name="milrev"/><ref name="gourley2003"/> The 5.7x28mm was finally standardized by NATO in February 2021.<ref name=":0" /><ref name=":1" />

===Present===
Further development of the P90 led to the creation of the ''P90 TR'' model, which has a [[Picatinny rail|MIL-STD-1913]] (Picatinny) triple rail interface for mounting accessories.<ref name="gourley2003"/> This model was introduced in late 1999 and continues to be offered alongside the standard P90.<ref name="gourley2003"/> More recently, the P90 has been offered to civilian shooters as the ''PS90'', a semi-automatic [[carbine]] intended for [[self-defense|personal protection]] and sporting use.<ref name="fnhusaps90">{{cite web |url=http://www.fnhusa.com/l/products/commercial/carbines/ps90-standard |title=FNH USA Carbines&nbsp;— The PS90 Standard |publisher=[[FNH USA]] |year=2012 |access-date=August 31, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120913050332/http://www.fnhusa.com/l/products/commercial/carbines/ps90-standard/ |archive-date=September 13, 2012 }}</ref>

The P90 is a [[selective fire]], [[Blowback (arms)|straight blowback]]-operated weapon with a cyclic [[rate of fire]] of around 850–1,100 rounds per minute.<ref name="jones2009"/><ref name="fnhusap90">{{cite web |url=http://www.fnhusa.com/l/products/law-enforcement/tactical/p90-series |title=FNH USA Tactical Weapons&nbsp;– The P90 Series |year=2012 |publisher=[[FNH USA]] |access-date=August 31, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120913064157/http://www.fnhusa.com/l/products/law-enforcement/tactical/p90-series/ |archive-date=September 13, 2012 }}</ref> The weapon is chambered for FN's 5.7×28mm ammunition. Its unusual shape is based on extensive [[ergonomic]] research.<ref name="jones2009"/><ref name="miller2001"/> The weapon is grasped by means of a thumbhole in the frame that acts as a [[pistol grip]], as well as an oversized [[trigger guard]] that acts as a [[foregrip]] for the shooter's support hand.<ref name="marchington2004"/> The P90 fires from a [[closed bolt]] for maximum accuracy, and its design makes extensive use of [[polymers]] for reduced weight and cost.<ref name="dettyTL2008"/> Overall, the weapon is relatively lightweight, weighing {{convert|2.5|kg|lb|abbr=on}} empty, or {{convert|3|kg|lb|abbr=on}} with a loaded 50-round magazine.<ref name="miller2001"/><ref name="marchington2004"/>

The P90 is notable for being fully [[ambidextrous]]—it can be operated by [[Handedness|right]] or [[Left handed|left-handed]] shooters with equal ease, and without making any modifications to the weapon.<ref name="marchington2004"/> FN Herstal has described it as the "first fully ambidextrous individual automatic weapon."<ref name=":0">{{cite web |url=http://www.fnherstal.com/html/p_90.htm |title=P90® Submachine Gun, 5.7x28mm |year=2002 |publisher=[[FN Herstal]] |access-date=October 15, 2011 |archive-url=https://web.archive.org/web/20020214012140/http://www.fnherstal.com/html/p_90.htm |archive-date=2002-02-14}}</ref> The [[charging handle]], [[magazine release]] and backup [[iron sight]]s are symmetrically distributed on both sides of the weapon, and the firing selector is located directly at the foot of the trigger, where it can be operated from either side by the shooter's trigger finger or support hand thumb.<ref name="fnhusap90"/> When fired, the P90 [[Downward ejection|ejects spent cartridge casings downward]] through a chute located behind the grip, so spent cases are kept out of the shooter's [[line of sight]].<ref name="marchington2004"/>

The P90 can be fitted with a [[Sling (firearms)|sling]] for greater ease of carry, and since the weapon has a fixed [[stock (firearms)|stock]] (as opposed to having a collapsing or [[folding stock]]), it can be quickly deployed when needed.<ref name="marchington2004"/><ref name="fnhp90">{{cite web |url=http://www.fnherstal.com/index.php?id=268&backPID=262&productID=63&pid_product=294&pidList=262&categorySelector=4&detail=&cHash=fb257c2c82 |title=Personal Defense Weapons: P90® Standard |year=2011 |publisher=[[FN Herstal]] |access-date=May 18, 2011 |archive-url=https://web.archive.org/web/20110317031144/http://www.fnherstal.com/index.php?id=268&backPID=262&productID=63&pid_product=294&pidList=262&categorySelector=4&detail=&cHash=fb257c2c82 |archive-date=March 17, 2011 |url-status=live }}</ref> The weapon's smooth, rounded contours prevent it from snagging on the shooter's clothing or equipment, and a small handstop at the weapon's front prevents the shooter's support hand from slipping in front of the [[Muzzle (firearms)|muzzle]] while firing.<ref name="miller2001"/><ref name="marchington2004"/> A hollow compartment inside the rear of the weapon's frame—accessed by removing the buttplate—allows for storage of a [[Firearm maintenance|cleaning kit]].<ref name="marchington2004"/>

The P90 was designed to have a length no greater than a man's shoulder width, to allow it to be easily carried and maneuvered in tight spaces, such as the inside of an [[Armoured fighting vehicle|armored vehicle]].<ref name="dockery2007"/> To achieve this, the weapon's design uses the unconventional [[bullpup]] configuration, in which the [[firearm action|action]] and magazine are located behind the trigger and alongside the shooter's face so that there is no wasted space in the [[Stock (firearms)|stock]].<ref name="dettyTL2008"/> The P90's dimensions are minimized by its unique horizontally mounted feeding system, wherein the [[Magazine (firearms)|box magazine]] sits parallel to the barrel on top of the weapon's frame.<ref name="dockery2007"/> The weapon overall has an extremely compact profile—it is the most compact fixed-stock submachine gun to be made.<ref name="dockery2007"/> The standard version of the weapon has an overall length of {{convert|500|mm|in|abbr=on}}, a height of {{convert|210|mm|in|abbr=on}}, and a width of {{convert|55|mm|in|abbr=on}}.<ref name="jones2009"/>

[[File:FN P90 Standard Submachine Gun Right Side.jpg|thumb|right|The P90 is fully ambidextrous]]
The P90 requires minimal [[Firearm maintenance|maintenance]], and it can be disassembled quickly and easily.<ref name="jones2009"/><ref name="wall2003"/> It is a modular firearm, consisting of four main component groups: the [[Gun barrel|barrel]] and optical sight group, the moving parts group, the frame and [[Trigger (firearms)|trigger]] group, and the [[Hammer (firearms)|hammer]] group. The P90's barrel is [[Forging|cold hammer-forged]] and [[Chrome plating|chrome-lined]], with an overall length of {{convert|263|mm|in|abbr=on}}.<ref name="fnhusap90"/> The barrel has eight [[rifling]] grooves with a right-hand [[twist rate]] of 1:231&nbsp;mm (1:9.1&nbsp;in), and it is equipped with a diagonally cut [[flash suppressor]] that also acts as a recoil compensator.<ref name="jones2009"/><ref name="fnhusap90"/> The stated service life of the barrel is 20,000 rounds.<ref name="dockery2007"/>

The P90 uses an internal hammer striking mechanism and a trigger mechanism with a three-position rotary dial fire control selector, located at the foot of the trigger. The dial has three settings: ''S''&nbsp;– safe, ''1''&nbsp;– semi-automatic fire, and ''A''&nbsp;– fully automatic fire. When set on ''A'', the P90's fire selector provides a two-stage trigger operation similar to that of the [[Steyr AUG]] assault rifle—pulling the trigger back slightly produces semi-automatic fire, and pulling the trigger fully to the rear produces fully automatic fire.<ref name="marchington2004"/>

Particularly significant to the design of the P90 is the small-caliber, high-velocity bottlenecked cartridge it uses. The 5.7×28mm cartridge was created by FN Herstal in response to a NATO requirement that called 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]])—roughly half as much as a typical 9×19mm cartridge—allowing the same number of rounds to be carried for less weight, or allowing more rounds 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}}</ref><ref name="fortierusg02">{{cite web |url=http://www.handgunsmag.com/ammunition/hg_militarytoday_200811 |title=Military Ammo Today |author=Fortier, David |year=2008 |publisher=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 has a relatively small diameter, an unusually high number of cartridges can be contained in a 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 |publisher=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]] (when fired from a pistol), but it produces roughly 30&nbsp;percent less [[recoil]] than the 9×19mm cartridge, improving [[muzzle rise|controllability]].<ref name="fortierusg02"/> Due to its high velocity, the 5.7×28mm exhibits an exceptionally flat [[trajectory]], compared to typical pistol ammunition.<ref name="dockery2007"/><ref name="wall2003"/>

One of the design intents for the standard 5.7×28mm cartridge type, the ''SS190'', was that it has the ability to penetrate [[Kevlar]] [[ballistic vest|protective vests]] that stop conventional pistol bullets.<ref name="fortierusg02"/> Fired from the P90, the 5.7×28mm SS190 has a muzzle velocity of roughly 716&nbsp;m/s (2,350&nbsp;ft/s, Mach 2) and can penetrate the NATO [[CRISAT]] vest or a [[ballistic vest#Performance standards|Level IIIA]] Kevlar vest at a range of {{convert|200|m|yd|abbr=on}}.<ref name="wall2003"/><ref name="fortierusg02"/> FN states an effective range of {{convert|200|m|yd|abbr=on}} and a maximum range of {{convert|1,800|m|yd|abbr=on}} for the 5.7×28mm cartridge when fired from the P90.<ref name="jones2009"/>

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 the risk of [[ricochet]].<ref name="cutshaw2006"/><ref name="humphries2008"/> The lightweight projectile 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}}, posing greater risk of collateral damage in the event of a miss.<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 SS190 projectile does not rely on fragmentation or the expansion of a [[hollow point bullet|hollow point]], the cartridge (and 5.7×28mm weapons) is considered suitable for military use under the [[Hague Convention of 1899]], which prohibits the use of [[expanding bullet]]s in [[warfare]].<ref name="bahde2009"/>

===Feeding===
The P90 uses a unique horizontally mounted feeding system—patented in the United States—that contributes to the weapon's compact profile and unusual appearance.<ref name="dockery2007"/> ''U.S. Patent 4,905,394'' ("Top mounted longitudinal magazine") was awarded in 1990, naming René Predazzer as the sole inventor.<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=4905394.PN.&OS=PN/4905394&RS=PN/4905394 |title=U.S. Patent 4,905,394 (Top mounted longitudinal magazine) |publisher=[[United States Patent and Trademark Office]] |access-date=July 15, 2010 |archive-url=https://web.archive.org/web/20151019115604/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=4905394.PN.&OS=PN%2F4905394&RS=PN%2F4905394 |archive-date=October 19, 2015 |url-status=live }}</ref> The [[Magazine (firearms)|detachable box magazine]] is mounted parallel to the P90's barrel, fitting flush with the top of the weapon's frame, and it contains 50 rounds of ammunition which lie in two rows facing left, offset 90° from the bore axis.<ref name="marchington2004"/> As the cartridges are pushed back by spring pressure and arrive at the rear end of the magazine, they are fed as a single row into a spiral feed ramp and rotated 90 degrees, aligning them with the [[Chamber (firearms)|chamber]].<ref name="marchington2004"/> The magazine body is composed of polymer, and it is translucent to allow the shooter to see the amount of ammunition remaining at any time.<ref name="marchington2004"/>

The MC-10-80 has an anodized aluminium housing, and has a similar black reticle. The night reticle for both the HC-14-62 and the MC-10-80 consists of an open ''T'' that is primarily illuminated by a [[Tritium illumination|tritium module]], and, in the HC-14-62, ambient light drawn in by an upward-facing collector.

The illuminated reticle makes the sight more versatile in a variety of different conditions.{{Citation needed|date=November 2021}}

The P90 has provisions for mounting a number of different types of accessories, including [[tactical light]]s and [[laser sights|laser aiming devices]]. A sling can be attached to the P90 for greater ease of carry, or it can be fitted with various [[sound suppressor]]s such as the Gemtech ''SP90'', which was designed specifically for the weapon in cooperation with FN Herstal.<ref name="jones2009"/> This [[stainless steel]] suppressor with a black oxide finish is built according to [[MIL-SPEC]]s, including [[saltwater]] [[corrosion resistance]].<ref name="jones2009"/> It has a length of {{convert|184|mm|in|abbr=on}}, a diameter of {{convert|35|mm|in|abbr=on}} and a weight of {{convert|680|g|lb|abbr=on}}.<ref name="jones2009"/> When [[speed of sound|subsonic]] ammunition is used in conjunction with the suppressor, it reduces the sound signature of the P90 by 33&nbsp;[[Decibel|dB]].<ref name="jones2009"/> A small case collector pouch for the P90 is available which fits over the ejection port and collects spent cases as they are ejected downward; the pouch will collect up to one hundred cases before filling.<ref name="gourley2003"/><ref name="wall2003"/>

The '''PS90''' is a semi-automatic [[carbine]] variant of the P90, intended for civilian shooters for personal protection and sporting use;<ref name="fnhusaps90" /> it was introduced in 2005, and continues to be offered in several configurations.<ref name="fnhusaps90"/><ref name="detty2008">{{cite web |url=http://www.fnhusa1.com/PDF/reviews/0801PS90policemag.pdf |title=FNH USA PS90 Carbine |author=Detty, Mike |date=January 1, 2008 |publisher=Police Magazine |access-date=October 14, 2009 |archive-url=https://web.archive.org/web/20120425014231/http://www.fnhusa1.com/PDF/reviews/0801PS90policemag.pdf |archive-date=April 25, 2012 |url-status=usurped }}</ref> The PS90 will accept the standard 50-round P90 magazines, but the gun is supplied with a magazine that is blocked to a capacity of 10 or 30 rounds, allowing it to be sold in jurisdictions where magazine capacities are [[Gun laws in the United States (by state)|restricted by law]].<ref name="detty2008"/>

In order to be legal for purchase by civilians without obtaining a tax stamp for a Short Barreled Rifle (SBR) as defined by the United States [[National Firearms Act]], the PS90 carbine has an extended {{convert|407|mm|in|abbr=on}} barrel and is semi-automatic, with a trigger pull of approximately {{convert|31|-|36|N}}.<ref name="rodriguez2008"/><ref name="detty2008"/> The lengthened barrel has eight [[rifling]] grooves, with a right-hand [[twist rate]] of 1:229&nbsp;mm (1:9 in) and a rifled length of {{convert|376|mm|abbr=on}}; the muzzle is equipped with a fixed "birdcage" type [[flash suppressor]].<ref name="detty2008"/>

The ''PS90 Standard'' is the current model of the PS90 offered by FN Herstal.<ref name="fnhusaps90"/> It features a MIL-STD-1913 (''Picatinny'') rail fitted to the top of the receiver, which allows the shooter to mount their preferred optical sight.<ref name="fnhusaps90"/> The rail includes a set of integrated iron sights, as backup in case the primary sight is damaged.<ref name="fnhusaps90"/> As of 2019 the PS90 Standard is available with a black frame.<ref name="fnhusaps90"/>

====PS90 SBR====
The ''PS90 SBR'' variant is functionally identical to the “PS90 Standard”, but instead of the extended 16 inch barrel, this variant retains the standard 10.5 inch barrel of its selective-fire counterpart, thus making it the ballistic equivalent, in semi-automatic only form. The PS90 SBR is not usually listed on FN Herstal's website, but is offered commercially through third-party extensions. These are made either through factory standard layouts, or conversions made by swapping the barrel. This renders the weapon a “short barreled rifle”, and thus the required tax stamp is necessary in order to purchase and/or transfer it. The weapon is regulated as “Title II”, and special certification is required in most states. As with all factory standard PS90 receivers special welding is in place to complicate full auto conversion.{{Citation needed|date=November 2021}}

====PS90 TR====
The ''PS90 TR'' is now discontinued.<ref name="fnhusaps90"/> It featured a "Triple Rail" receiver assembly identical to that of the P90 TR.<ref name="fnhusaps90"/> The top of the receiver consisted of an MIL-STD-1913 (''Picatinny'') rail, allowing the shooter to mount their preferred optical sight.<ref name="detty2008"/> Two polymer side rails—one on each side of the receiver—were included for mounting secondary accessories, such as lasers or tactical lights.<ref name="detty2008"/> Like the PS90 Standard, the PS90 TR was available with either an [[olive drab]] or black frame.<ref name="fnhusaps90"/> As of 2013, the PS90 TR model is no longer listed by FNH USA.<ref name="fnhusaps90"/>
