FN America FN 509 LS Edge 9mm Pistol 5" Barrel - 17 Rd

Engineered for elite performance in the most demanding environments, the FN 509 LS EDGE represents the pinnacle of FN America’s striker-fired handgun innovation. Designed for split-second decision-making, precision control, and uncompromising reliability, this full-size 9mm pistol blends competition-grade enhancements with duty-ready durability.

At its core, the LS EDGE features a lightened long slide with lightning cuts to reduce reciprocating mass, improving recoil control and shot-to-shot speed. The crisp flat-faced trigger with an average 4.5 lb pull delivers a consistent, predictable break, helping shooters achieve tighter groups and faster follow-up shots under pressure.

The Grey PVD stainless steel slide pairs with a rugged polymer frame finished in black for a balance of durability and corrosion resistance. Enhanced ergonomics include interchangeable backstraps, ambidextrous controls, an oversized magazine release, and a flared aluminum magazine well—ensuring fast reloads and superior handling in high-stress environments.

Optics-ready capability is built in through the FN Low-Profile Optics Mounting System (FNOPTICMOUNT), allowing seamless red dot integration. Combined with green fiber optic front sights and a blackout rear MRD sight, the LS EDGE delivers fast target acquisition across a wide range of lighting conditions.
