FN 509M Tactical Bundle 9mm, 4.5in Threaded Barrel, 5 Mags

The FN 509M Tactical is a midsize, optics-ready semi-automatic pistol chambered in 9mm. It ships as a package with multiple magazines and a threaded 4.5-inch barrel suitable for use with muzzle devices. The slide is prepared for micro red dots via FN’s Low-Profile Optics-Mounting System and includes suppressor-height 3-dot night sights for co-witnessing.

Designed for multi-role use — from everyday carry to range work and duty applications — the platform combines a full-hand grip frame with a selection of magazines for higher round-count sessions and a balanced recoil impulse for consistent follow-up shots.
