Flat Action Trigger Kit FN 509
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.
- 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
For use in the FN 509 (including Tactical, Midsize and Compact models).

Note regarding color trigger variations from Apex:
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 our Customer Service staff to discuss replacing your trigger.
We apologize for any inconvenience.
