FN America 509 9mm Striker Fired Pistol

FN America’s 509 MRD full-size pistol is built for shooters seeking a duty-style platform suitable for personal or home defense. The striker-fired design chambers 9mm ammunition through a 4.50″ cold hammer-forged barrel, which incorporates FN’s signature recessed target crown to preserve rifling integrity and sustain accuracy over the firearm’s service life. The slide and frame geometry deliver a secure grip and help manage recoil impulse. This package includes an FN logo soft case, two 17-round capacity magazines, three interchangeable backstraps, four MRD mounting plates, an owners manual, and a gun lock. The pistol features FN’s patented Low Profile Optics Mounting System for users who want to run a full-sized duty-style pistol for personal or home defense.
