Product Description

The FN 509 Midsize MRD 9mm pistol combines versatility with proven performance for sporting and recreational shooters. This striker-fired mid-size platform features a 4″ barrel and ships with two 15-round magazines, giving you ample capacity for range sessions and practice. The optics-ready slide accepts modern red dot sights, letting you customize your setup to match your shooting style.

Balanced Design for All Shooters

FN engineered the 509 Midsize MRD with ambidextrous controls, making it comfortable for left- and right-handed shooters alike. The mid-size frame strikes a balance between concealability and shootability. Additionally, the polymer construction keeps weight down without sacrificing durability. This design makes the 9mm pistol accessible to new shooters while satisfying experienced hands.

Precision Performance

The 4″ barrel delivers consistent accuracy across distances typical for recreational and competitive shooting. Furthermore, the striker-fired action provides a predictable trigger and fast reset between shots. The flat dark earth finish resists corrosion during outdoor use. Therefore, the FN 509 Midsize MRD rewards both precision work at the range and dynamic shooting scenarios.

Optics Ready Out of the Box

Modern shooters expect mounting options for red dot sights. The optics-ready slide on this FN 509 model lets you add a sight without gunsmithing. This feature appeals to competitors, hunters, and target shooters who want flexibility. In addition, the non-manual safety design simplifies operation and speeds up target engagement.
