Announced in May, the company began taking pre-orders in September much to the delight of FN fans. The Action Enhancement Kits incorporate Apex’s patent-pending design into FN’s striker-fired pistol series. Mounted on a proprietary Apex trigger bar, the Flat-Faced Trigger partners with an Apex Sear to reduce the trigger pull weight. Apex says approximate pull weight is within the 5.5-pound range.
Kits for the FN 509 include a black anodized as well as a red Cerakoted version. The Action Enhancement Kits for the FNS and FNS Longslide — 2014 manufacture date and later — include black anodized and FDE anodized models. Rounding out the series is the Action Enhancement Kit for the FNS Compact offering black anodized and FDE anodized versions.
Apex offers step-by-step installation videos on its YouTube channel to make installation painless. Trigger pricing starts at $149.
