Apex Tactical Specialties Curved Action Enhancement Trigger Kit for FN 509 Models 119-126, FNS-c, Black

Overview

The Apex Tactical Specialties Action Enhancement Trigger Kit is a drop-in upgrade designed for current FN 509 pistol models—including Tactical, Midsize, Compact, and Edge Series—as well as FNS Compact (FNS-C) models. The patent-pending design replaces the factory components with a curved action enhancement trigger, trigger bar, and performance sear without requiring permanent fitting. When installed, the kit reduces trigger pull weight to approximately 5.5 pounds while shortening pre-travel, over-travel, and reset distance. It delivers a crisp trigger break and maintains factory safety values via a center-mounted pivoting safety.
