FN America® FN 509® Midsize 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.

It starts with the 4" cold hammer-forged stainless steel barrel, which was upgraded with a recessed target crown for accuracy. Both the slide and barrel geometry have been improved to help lower the bore axis: recoil travels straight into the meat of your hand, where you can best control it, keeping the muzzle on-target for fast follow-up shots. The original sights have been replaced with flat-edge luminescent combat sights that provide fast low-light targeting and can be used to rack the pistol one-handed in an emergency. For durability's sake, the 509 was outfitted with a captive double-nested recoil spring to reduce wear and enhance what was already a very long expected service life.

The new 509 Midsize retains the 4" barrel of the standard, but utilizes a mid-size frame that's much easier to conceal. The 9mm Pistol is compatible with all FN 509 magazines with use of a sleeve (sold separately). The improved controls aid in manipulation, the new improved texturing on the 2 included backstraps provides better recoil management and a new, flatter-faced trigger allows for more controllable trigger press and cleaner break.

  • Captive double-nested recoil spring reduces wear and enhances service life

  • Deep-cut front and rear slide serrations for easy manipulation

  • 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

  • Loaded chamber indicator
