FN America® FN 509® Midsize MRD 9mm Semi-automatic Pistol

Developed for the US Military's Modular Handgun System Competition—and backed by over 1 million rounds of testing in the most demanding conditions—the FN 509 represents the pinnacle of the combat pistol. It's built on the proven architecture of the FNSTM Compact, but every aspect—both internal and external—was scrutinized and analyzed to enhance ergonomics, ammunition compatibility, and—above all—reliability.

The 509 Midsize MRD retains the 4" barrel of the standard 509, but features a smaller mid-size frame and all-new Low-Profile Optics Mounting System. Like the full-size 509, the barrel features a recessed target crown for enhanced accuracy, and the bore axis is extremely low. That low bore axis means recoil travels straight back into the meat of your hand, where you can best control it.

The most notable improvement, though, is the Low-Profile Optics Mounting System, which allows you to directly mount 10 different popular red dots via the included plates. Adding a red dot to your carry pistol has never been easier.

  • Low-Profile Optics Mounting System allows for easy direct mounting of more than 10 popular red dots
  • Mid-size frame is easier to conceal than the full-size 509
  • Very low bore axis: recoil is directed right into the meat of your hand—not over the top of it—for better control
  • 4" cold hammer-forged stainless steel barrel with recessed target crown for exeptional durability and accuracy
  • Captive double-nested recoil spring reduces wear and enhances service life
  • Flat-edge rear sight can be used to rack the slide one-handed in an emergency
  • Deep-cut front and rear slide serrations for easy manipulation
  • External rotating extractor for reliable extraction
  • Aggressive grip texturing: deep stippling on the meat of the grip, skateboard tape-style grip at the top,
  • Double action trigger with 5.5-7.5 lb. pull
  • Melonite slide finish for superior durability
  • Polished chamber and feed ramp
  • Loaded chamber indicator
  • Compatible with FN 509 17-rd. and 24-rd. magazines with appropriate magazine sleeves (not included)
  • Includes (2) 15-rd. magazines, (2) interchangeable backstraps, and mounting plates for direct mounting more than (10) popular red dots
