Designed to be easily concealable while still offering full-size 9mm handgun performance, this mid-size FN 509 for sale at Mister Guns is built on the proven architecture of the FNS™ Compact, and further developed with help from the weapons experts at FN America. It is almost a half inch shorter than the standard FN 509, making it even more easy to conceal while still allowing for a full pistol grip.

Tested extensively for reliability, ammunition compatibility and durability, and available for commercial, law enforcement, and military use, the 509 FN pistol features a polymer frame with replaceable steel frame/slide rails; black polymer grip with interchangeable backstraps featuring improved texturing for better recoil management and faster follow-up shots in all conditions; a cold hammer-forged, stainless steel barrel with recessed target crown, polished chamber and feed ramp; and an easily-racked steel slide with an external extractor, improved front and rear cocking serrations for easy manipulation, and a loaded chamber indicator that provides visual indication when there is a round currently in the chamber, thereby enhancing safety.

This FN 509 gun also features a new, flatter faced trigger that allows for more controllable trigger press and cleaner break, fixed 3-dot luminescent sights, a MIL-STD-1913 accessory mounting rail for the installation of accessories like lights and lasers, as well as a fully ambidextrous slide stop lever and magazine release easily accessible to both right and left-handed users.

Two (2) 15-round or 10-round high-visibility magazines ship with the striker-fired FN 509 9mm pistol that is compatible with all FN 509 magazines; and these magazines each feature a low-friction follower and a polymer base plate. Two interchangeable backstraps, a locking device, an FN logo soft pistol case, and an owner’s manual are also present in the box.
