The FN 509 9mm was the entry from FNH into the Army's Modular handgun competition. Based off the FNS striker fired pistol, with some upgrades to meet the requirements of miltary testing. Integrated 1913 frame mounted rail, and fully ambidextrous controls without swapping parts, from slide stop to mag release the FN 509 9mm is great for left handed shooters. Lightweight polymer frame, ergonomic grip and interchangeable backstraps with texture grip rough enough to stay solid in your hand under inadverse conditions. The barrel of the FN 509 9mm is hammer forged for long term durability and has a recessed target crown for exceptional accuracy. The blackened stainless steel slide is home to front and rear cocking serrations and 3-dot luminescent combat style sights. With a full compliment of ammunition, 17rds per magazine, the FN 509 9mm carries enough ammo to get the job done in virtually any situation. The FN 509 is the result of nearly 1 million rounds of testing, now available to the civilian market.
