Design and handling

The FN 509 MT is chambered in 9mm Luger, a caliber prized for controllable recoil, magazine capacity, and wide ammunition availability for both defensive and training use. FN built the pistol with a 4.5″ cold hammer-forged stainless steel barrel that is recessed and crowned for accuracy and features 1/2×28 threads for suppressor compatibility. The matte black polymer frame includes a MIL-STD-1913 accessory rail for lights or lasers and fully ambidextrous controls to suit left- and right-handed operators.

Optics and sighting system

FN equipped the pistol with the Low-Profile Optics-Mounting System and included a Holosun 407C red dot for fast target acquisition. Suppressor-height 3-dot night sights are present as a backup iron option, and improved front and rear cocking serrations aid slide manipulation under stress or with gloves.

Trigger, safety, and tactical features

The flat-faced trigger provides a predictable break and positive reset for follow-up shots. Mechanical features include an external extractor, a loaded chamber indicator, and combat-style ergonomics tuned toward defensive work. Magazine options include the standard 15+1 capacity or an extended 24+1 magazine for extended drills and lower reload frequency during training.
