509m Tactical 9mm 4.50in 15 + 1 Fde Semi Auto Pistol - Optic Ready & Threaded

The FN 509 Tactical features the company’s U.S Patent No. 10/352,654 Low-Profile Optics Mounting System that enables the platform to accept more than ten commercially-available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights and remain adaptable to future optics releases with no requirement of direct milling of the slide. The slide cap, for use when not shooting with an optic, has raised sight wings that protect iron sight alignment if the pistol is dropped or jostled, and provides a textured ramp for racking the slide against a belt loop, pant pocket or boot. An FN signature stainless-steel, threaded barrel with target crown accepts the bulk of 9mm suppressors available and thread cap with integrated O-ring to prevent loosening during use complete the top end. Includes one 15rd magazine and four 24rd magazines.
