Apex Tactical FN 509 Action Enhancement Trigger Kit - Curved/Black


Apex originated the drop-in trigger kit for the FN 509. The patent-pending design of the Action Enhancement Trigger Kit for the FN 509 (with Curved Trigger) makes a huge difference in the trigger pull characteristics and immediately became a must-have for 509 owners.



  • Reduce trigger pull weight to approx. 5.5 lbs.
  • Reduce trigger pre-travel, over-travel and reset distance
  • Deliver a crisp trigger break
  • Maintain factory safety values with a center mounted pivoting safety
  • Direct drop-in replacement, no fitting required


For Use In:

  • FN 509 (including Tactical, Midsize and Compact models)
  • FN 509 LS Edge
  • FN FNS Compact all available calibers


Please Note: The sear you receive may appear different than the sear in the photo.  Rest assured that if the Apex logo was laser engraved on it, the sear has received all of the necessary processes and is correct.
