Love Your FN Pistol But Wish for a Better Trigger? Here's the Solution!

Apex Tactical's FN 509 Action Enhancement Kit will give your pistol a lighter, smoother trigger pull with less pre-travel, shorter overall pull length, AND a shorter (therefore faster) reset. Like Apex's Action Enhancement kits for the S&W M&P and SIG pistols, it's an easy-to-install replacement for your 509's factory trigger, trigger bar, and sear - basically a drop-in DIY trigger job! FN 509 owners who are a little handy with tools and comfortable following instructions can do the job themselves.

  • Drop-in replacement for factory trigger, trigger bar & sear
  • Will not alter function of factory safeties
  • Machined aluminum "flat-faced" trigger shoe with matte black hard-anodized finish
  • Polished stainless steel sear & trigger bar
  • Fits FN 509 chambered in 9mm Luger OR .40 S&W
  • Available in Black, Red, and FDE

When installed, the Apex FN 509 Action Enhancement Kit will reduce the trigger pull weight to approximately 5.5 lbs.; actual weight will vary slightly from one FN 509 to another. Rather than the OK-but-not-great feel of the plastic factory trigger, Apex's trigger is made of machined aluminum with their trademark "Flat Face." Many shooters prefer the flat face for its more comfortable feel and precise control akin to a 1911 target trigger. At the same time the "AEK" will not alter the function or reliability of your 509's factory trigger safety, firing pin safety, drop safety, or out-of-battery safety.
