The FN 509 Compact MRD Pistol offers unparalleled modularity with an optics-ready low profile mounting system allowing it to pack full-size punches into a compact package. The FN 509 Compact Pistol is chambered in 9mm Luger and features a 3.7-inch barrel with a standard 12 + 1 round capacity.

The patented FN low profile mounting system readily accepts almost all commercially available reflex sights and other small red dot optics. Improved controls facilitate maneuvering, the improved texture provides better recoil management, and the new flat-face trigger makes it easier to control your trigger pull in rapid-fire. The shortened grip offers easier concealment, while the MIL-STD allows the user to attach a number of accessories to the FN 509 Compact Optics. The FN 509 Compact also features high profile night sights for better low light target acquisition.
