Key features and tactical benefits

Optics-ready and sighting

The inclusion of the Holosun 407C red dot provides a fast sight picture for close-quarters engagement and follow-up shots. Combined with combat-style iron sights, the FN Low Profile mounting system keeps the optic low for a natural co-witness and minimal sighting transition.

Controls, ergonomics, and durability

FN improved the controls with fully ambidextrous levers, a flat-faced trigger, enhanced front and rear serrations, and upgraded texture on the two included backstraps to tailor grip and control. The cold hammer-forged stainless steel barrel with a recessed target crown and the MIL-STD-1913 accessory rail make this pistol capable both on and off duty.

Capacity, accessories, and value

Chambered in 9mm Luger, the 509M MRD ships with two magazines providing 17+1 and 24+1 capacity options depending on magazine selection, a hard case, locking device, and owner’s manual. At $849.99, it competes strongly for shooters seeking an optics-ready defensive pistol with factory-mounted red dot and premium barrel construction. View product details and pricing.
