The FN 509 Compact Tactical, available in both black and FN-signature flat dark earth (FDE), is a 9mm striker-fired pistol that features a threaded barrel, the patented FN Low-Profile Optics-Mounting System,™ and the ability to accept high capacity FN 509 magazines.

The 4.32-inch cold hammer-forged threaded barrel is housed within the compact 3.6-inch slide with optics-mounting system that accepts more than 10 miniature red dots. When using the optics-mounting system, the suppressor-height night sights aid in co-witness and while not in use, the slide cap provides a serrated surface for racking the slide from any surface. The compact frame features the FN 509-signature enhanced grip texturing for secure hold and interchangeable backstraps for a customized fit.

The pistol ships with the optics-mounting kit, one each of the 12-, and 24-round capacity magazines with the appropriate grip sleeves inside of an FN-branded soft-sided case.
