For shooters seeking a duty-grade midsize pistol that’s ready for optic use and suppressor integration straight from the box, attention to detail and real-world functionality matter more than marketing copy. This review breaks down why this platform is built to serve serious training, protection, and tactical needs.

FN 509MT

Design & Features

The FN 509MT combines a 4.5″ black target crown/threaded steel barrel with a flat dark earth polymer frame and MIL-STD-1913 accessory rail for lights and lasers. It ships optic-ready and includes a Holosun 407C red dot, making immediate red-dot use a non-issue. The optics-mounting interface is FN’s low-profile system, and the slide is optic cut with enhanced front and rear cocking serrations for positive manipulation.

Barrel, Sights, and Suppressor Readiness

Barrel & Accuracy

The cold hammer-forged stainless steel barrel with a recessed target crown improves longevity and potential accuracy. The threaded muzzle supports direct-attach suppressors and compensators, expanding the pistol’s mission flexibility.

Sights

Suppressor-height 3-dot night sights are provided to co-witness with the Holosun 407C or function independently when optics are removed. A loaded chamber indicator and external extractor add operational clarity and reliability in dynamic environments.

Controls, Ergonomics & Capacity

Fully ambidextrous controls, a flat-faced trigger, and an ergonomically sculpted FDE frame make the 509MT intuitive for right- and left-handed shooters. Standard capacity is 15+1 with the option of a 24+1 magazine for extended training sessions or reduced reload frequency. Chambered in 9mm Luger, this platform balances manageable recoil, high-capacity magazines, and wide ammo availability for training and defensive use.
