FN America® FN 509TM 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 list goes on and on. Deep-cut slide serrations. Aggressively-stippled grip with added texturing on the front and backstrap. Rotating extractor for positive no-fail extraction. Even the magazine has been upgraded for easier removal when buried in sand. The bottom line is this: the FN 509 is a true military-grade Pistol that shoots like a dream, eats any ammo you throw at it, and keeps running in the worst conditions imaginable.
