The FN 509 Midsize Tactical is the multi-role pistol for EDC, home defense and duty use. This exclusive, optics-ready package includes four 24-rd magazines and one 15-rd magazine, with a flat-faced precision trigger. With a factory-milled slide, it's ready to mount most micro red dots. FN's Low-Profile Optics-Mounting System is the industry's most adaptable optics mounting platform, allowing co-witness with tall tritium night sighs on the slide. A smooth, drop-safe trigger has a positive wall before a clean break. This model features an FDE finish and a threaded barrel.
