FN 509 T 9mm – FN America

The FN 509 T is a full-size, multi-role semi-automatic pistol designed for duty use, range work, and defensive carry where a larger-frame handgun is appropriate. It is built with an optics-ready slide and a threaded barrel to support a variety of accessory setups while retaining factory reliability.

The pistol combines a polymer frame with an applied colored finish and an ergonomically textured grip for secure handling. Controls are configured for common right- and left-side operation, and the slide is finished and cut to accept micro red dot optics while preserving suppressor-height three-dot night sights.
