FN 66-100843: The FN 509 LS EDGE is the ultimate tactical pistol. This pistol is made for the most demanding environments where split-seconds matter and holding the advantage in your hands is a must-have. With a crisp and flat-faced trigger, flared aluminum magazine well, and lightening-cut long slide, these in-factory enhancements complement the FN 509 Low-Profile Optics-Mounting System and fiber optic sight package to help shooters master firearm control and build expert marksmanship while allowing for quick follow up shots. Each high-performance feature was chosen to give you every advantage. Chambered in 9mm Luger and tested with a million rounds of live fire, it's equally at home defending freedom, or crushing the competition at a match.
