FN 509 Development History
FN Herstal’s Legendary Status
FN Herstal (Fabrique Nationale d’Herstal) is one of the world’s most influential firearms manufacturers, founded in 1889 and headquartered in Liège, Belgium. FN’s designs have profoundly influenced modern small arms development, with many classic designs still in service with militaries worldwide.
FN Classic Weapons:
- FN FAL: “The Right Arm of the Free World,” the main battle rifle of Western forces during the Cold War
- FN MAG / M240: NATO standard medium machine gun
- FN Minimi / M249 SAW: U.S. military squad automatic weapon
- FN P90 / Five-seveN: Innovative personal defense weapon system
- FN SCAR: Current U.S. Special Operations Command rifle
XM17 MHS Competition (2015-2017)
In September 2015, the U.S. Army and Air Force jointly launched the XM17 Modular Handgun System (MHS) competition, aiming to replace the Beretta M9 pistol that had served for over 30 years.
Competition Requirements:
- 9mm caliber
- Modular design (adjustable grip size)
- Red dot optics compatible
- Suppressor compatible
- Extremely high reliability standards
8 Competing Manufacturers:
- SIG Sauer (P320) ← Final Winner
- FN America (FN 509 prototype)
- Glock (G17/G19 MHS)
- Beretta (APX)
- Smith & Wesson (M&P)
- CZ-USA
- General Dynamics / Smith & Wesson
- Detonics Defense
FN 509 Development Process
To meet the rigorous MHS standards, FN substantially improved upon their existing FNS-9 Compact platform. FN also enlisted legendary retired Delta Force operator Larry Vickers as a consultant to ensure the design met real-world combat requirements.
Development Milestones:
- Over one million rounds of test ammunition for reliability validation
- Both internal and external structures optimized for MHS requirements
- Integration of practical feedback from industry experts
Competition Results & Commercialization (2017)
In January 2017, SIG Sauer’s P320 won the XM17 competition, becoming the U.S. military’s new standard-issue pistol (M17/M18).
Why FN Didn’t Win:
- SIG offered both full-size and compact versions simultaneously
- SIG had an ammunition supply partnership with Winchester
- FN’s design reportedly required more modifications to fully meet military requirements
However, FN didn’t abandon their investment. In 2017, FN America refined their competition design for the civilian market, officially naming it the FN 509.
