The FN 509F MRD-LE1 delivers more precision and versatility than any other duty-rated handgun. Building on the proven FN 509 lineup, the exclusive upgrades for law enforcement place every advantage in officers’ hands, with unmatched accuracy from a striker-fired handgun. Making up the new high-performance package is a conical striker, flat-faced duty-rated trigger, and the FN Low-Profile Optics-Mounting System™?, for fast sight acquisition and consistent shot placement.

3-dot tritium sights co-witness with the MRD, for maximum sighting versatility and a clean sight picture, day or night. The industry’s most comprehensive and adaptable optics mounting platform, allows armorers to quickly mount common duty-rated optics.

The 509 MRD-LE is the choice for agencies that can’t settle for less than 100% reliability. With unmatched longevity in the most demanding trails, the FN 509 platform has been tested beyond 1-million rounds, chosen by departments for its compatibility with a wide variety of training and duty ammunition. With a polished feed ramp and chamber, consistent feeding and extraction exceed every standard.

The smooth, drop-safe trigger compliments the perfect sight picture. FN’s precision trigger and high-performance striker, adapted from the FN 509 LS Edge™, has a positive wall before a clean break, improving accuracy for all officers. With a target-crowned, hammer-forged barrel, a lifetime of tight groups is in reach.
