FN FNS

{{Main|FN FNX}}

The FNS pistol is based on the FN FNX.

The FNS has similar ergonomics to the FNX but introduces a double-action, striker-fired functionality.{{cite web |url=https://nationalinterest.org/blog/buzz/forget-glock-could-gun-be-one-take-firearm-champ-58092 |title=Forget Glock: Could This Gun Be the One To Take On the Firearm Champ? |first=Charlie |last=Gao |website=nationalinterest.org |date=May 18, 2019 |accessdate=March 13, 2020}}{{cite web |url=https://fnamerica.com/pistols/fns-series/ |title=FNS Series |website=fnamerica.com |accessdate=March 13, 2020 |archive-date=19 February 2020 |archive-url=https://web.archive.org/web/20200219072401/https://fnamerica.com/pistols/fns-series/ |url-status=dead }}

The FNS series of the pistols all include ambidextrous magazine releases, and slide stop release levers.{{cite web|title=FNS-9|url=http://www.fnherstal.com/index.php?id=269&backPID=263&productID=172&pid_product=295&pidList=263&categorySelector=5&detail=&cHash=fcfd50b577|publisher=FN Herstal|accessdate=19 December 2012}}

The FNS has four standard safety features:

1. A trigger safety, similar to that seen on a Glock, which prevents the weapon from discharging without pressure on the trigger.
2. A firing pin safety which prevents the striker from hitting the primer without the trigger being pulled.
3. A drop safety which prevents the sear from rotating to release the striker unless the trigger is pulled.
4. An out-of-battery safety which prevents the sear from releasing the striker if the slide is not fully forward.

As a fifth safety feature, the FNS pistols can also have an optional manual safety.

Like other FN pistols, the FNS is a short-recoil-operated pistol. It is a pre-set striker fired semi-automatic pistol, meaning the trigger system is of the hammerless short double-action-only type. The trigger pull is between {{convert|25|N|lb-f|1|lk=on|abbr=on}} and {{convert|35|N|lb-f|1|lk=on|abbr=on}}.

All variations also include a hammer-forged stainless steel barrel, Picatinny rail, fixed three-dot combat sights (standard or night sights), and a loaded chamber indicator on the right side.

The pistol is chambered for the 9×19mm Parabellum and .40 S&W cartridges.

All versions are available in two finishes: a standard black finish featuring a dark colored/nitrided slide and matte black frame or a two-tone finish featuring a silver colored stainless steel slide and matte black frame.

At least one variant, the FNS-9C (compact) is available in solid dark earth coloration.

Introduced in 2012 designed in partnership with the Baltimore County Police Department specifically for the department.

{{Main|FN 509}}

A full size 9mm pre-loaded striker pistol, known as the FN 509, was introduced in early 2016 with it being part of the XM17 Modular Handgun System competition. It was released for public sale in 2017.

It is fully ambidextrous and comes in two versions, one version having manual safety and another without it. It also comes with a Picatinny rail for various attachments.{{Citation|last=DefenseWebTV|title=Milipol Paris 2017 News Internal State Homeland Security Police exhibition France Day 2|date=2017-11-22|url=https://www.youtube.com/watch?v=8_F1C6x6uCc&t=66|accessdate=2017-11-24}}

In 2015, officer Richard Vankeuren, a 20-year veteran of the Arizona Department of Public Safety, bumped his holstered FN FNS-40 into a bag he was carrying and the weapon went off, shooting him in the leg. The investigation concluded that a part of the bag had been tangled in the trigger, causing the firearm to go off.

However, in 2018, the state began testing the weapons further. The tests concluded that the pistols were capable of firing with the slide not fully in battery, and also that they could discharge if tapped.

The pistols were even observed to fire upon the simple impact resulting from re-holstering. This was the result of the trigger not resetting properly and the safeties failing to engage.{{Cite web|url=https://www.azmirror.com/2019/04/22/after-discovering-critical-flaw-in-gun-dps-quietly-replacing-guns-issued-to-all-troopers/|title = After discovering critical flaw in gun, DPS quietly replacing guns issued to all troopers|date = 22 April 2019}}

That same year, the Baltimore County Police Department claimed that they had encountered their own problems with their own FNS-40-L pistols firing when bumped.

The Baltimore police also claimed that they had encountered three separate incidents of the roll pin in the frame breaking, causing the trigger to completely fall out of the firearm.

The Arizona Department of Public Safety shared their testing results with the Baltimore County Police. On October 30, 2018, Baltimore County Police Chief Terrence Sheridan issued an Emergency Justification for a Replacement Service Weapon.

FN immediately addressed this by replacing the striker with a newer, improved design in each FNS-40 for both the Arizona DPS and the BCPD, at no cost to either agency.

FN also posted a Service Bulletin to the public with an offer of a free striker upgrade for those who wished to send their pistol in. FN also said that the malfunctions had only been observed in a lab environment, and that the malfunctions can only be replicated in FNS pistols manufactured before February 12, 2017.

FN did, however, maintain that the FNS design was thoroughly tested and that the situations that result in the misfires were unique and unlikely, and therefore did not initiate a recall. FN also claimed that the trigger pin is a part that requires periodic maintenance, and that in all three cases, the firearm was quickly reassembled.{{Cite web|url=https://fnamerica.com/press-releases/fn-america-llc-response-baltimore-county-police-department-statements-fns-40/|title=FN America, LLC Response to Baltimore County Police Department Statements on FNS™-40|date=3 January 2019}}{{Cite web|url=https://fnamerica.com/customer-support/fns-service-bulletin/#:~:text=FN%20recently%20became%20aware%20of,manufactured%20before%20February%2012%2C%202017.|title=FNS Service Bulletin}}

When the dust settled, both the Arizona DPS and the BCoPD made the decision to replace their FNS designs. Both the Arizona DPS and the BCoPD went from the .40-caliber FNS-40 to the 9mm Glock 17.{{Cite web|url=https://www.thefirearmblog.com/blog/2019/02/01/baltimore-county-pd-to-replace-fns-40-with-glock-17/|title=Baltimore County Police to Replace FNS-40 with Glock 17 Following Accidental Discharges -|date=February 2019}}

However, according to Arizona DPS spokesman Bart Graves and state trooper Kameron Lee, the decision to switch from the FNS to the Glock was made not because the department was unhappy with the pistols, but because FN had informed them that the company planned to discontinue the FNS that same year. Officer Lee claimed,

"We found an issue, FN fixed it, no guns we are carrying are faulty".
