FN 503 Pistol Semi-Automatic Pistol



The FN 503, inspired by FN’s legendary heritage, is the company’s first entry into the slim 9mm pistol market. The FN 503, roughly the size of your hand, conceals quickly and discreetly without compromising on features or performance.  The excellent trigger and soft recoil of this slim 9mm pistol make the FN 503 comfortable and controllable to shoot.


Arguably the best in its class, the all-metal trigger breaks crisply and consistently with an average of 5lb. trigger pull. The snag-free sights ensure a quick draw from any holster or bag. And, the enlarged controls make operation effortless when switching between the 6-round standard magazine and 8-round extended magazine.



  • Recessed target crown
  • Polished chamber and feed ramp
  • Oversized controls for easy operation
  • Comes with 6-round and 8-round extended magazine
  • Low-profile iron sights to prevent snags

Made In United States of America
