FN 509 LS Edge 9mm 5″ LS | 17+1 | Optics-Ready | 66-100843

The FN 509 LS Edge is a long-slide 9mm pistol built with an optics-ready slide, fiber-optic front sight and blackout rear notch, and a flared aluminum magwell to speed reloads. The 5″ hammer-forged barrel and lightening-cut long slide aim to balance weight and follow-up shot speed while the matte black polymer frame includes interchangeable backstraps for fit. This model ships with three 17-round magazines and multiple MRD mounting plates for common red-dot sights.

For an optic that pairs well with the 509 LS Edge, consider the Trijicon RMR Type 2, a compact red-dot that fits the Low-Profile Optics Mounting System and remains widely used on duty and competition pistols (priced under $1,000). Typical applications for this platform include competition shooting and precision range training.
