Apex Tactical Specialties has expanded its aftermarket upgrade options for the FN 509 series of pistols with the addition of a new curved trigger version of its popular Action Enhancement Kit. The new kit is available now for pre-order with orders scheduled to begin shipping on Tuesday, September 17.

The patent-pending design of the Apex Action Enhancement Kit for FN’s striker-fired FN 509 model pistols includes Apex’s Curved Action Enhancement Trigger mounted on an Apex designed proprietary Trigger Bar which is paired with an Apex Sear.

Overall trigger travel is optimized to provide a smooth uptake while delivering a crisp trigger break.
