Apex Tactical Specialties Apex Enhancement Trigger Kit for FN 509, Flat Dark Earth. 119-145


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 Flat-Faced Trigger) makes a huge difference in the trigger pull characteristics and immediately became a must-have for 509 owners. When installed, this kit will:

  • 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
  • UPC: 854263007708

Notice regarding color trigger variations Due to the nature of the anodize process and materials our triggers are manufactured from; our Flat Dark Earth (FDE) triggers are coming out as more of a burnt bronze color.  This color is a repeatable color, unlike the previous vendors who have attempted similar colors for us in the past.

If you receive an FDE trigger and are unhappy with the color, we urge you to contact Apex Tactical Customer Service to discuss replacing you trigger with one in Red or Black.

We apologize for any inconvenience.
