FN 509 Compact MRD with Compensator – FDE | 9mm | 4.02″ Barrel | 12rd & 15rd Mags

The FN 509 Compact MRD with Compensator in Flat Dark Earth delivers full-size performance in a carry-ready compact package. Chambered in 9mm Luger, this striker-fired pistol features FN’s patented Low-Profile Optics Mounting System, which accepts nearly all major red dot footprints, and a proprietary auto-indexing quick-detach compensator that reduces muzzle flip by approximately 25 percent for faster, more accurate follow-up shots.

The 509 Compact MRD comes standard with two magazines — a flush-fitting 12-round and an extended 15-round — giving you flexibility for concealed carry or range use. The optics-ready slide pairs with all-black co-witness iron sights, ensuring you’re ready to run iron or glass right out of the box. Ambidextrous controls make this pistol accessible for left- and right-handed shooters, while the two included backstraps and aggressive grip texturing provide a secure, customizable hold and improved recoil management.
