FN 509 9mm Optics-Ready Pistol – FDE w/ Vortex Viper Red Dot

The FN 509 is a duty-proven, striker-fired 9mm pistol designed to meet military and law enforcement performance standards while remaining approachable for civilian shooters. This example features an optics-ready slide paired with a Vortex Viper red dot, making it an excellent turnkey setup for defensive use, training, or range work right out of the box.

Finished in Flat Dark Earth (FDE), the FN 509 offers aggressive grip texturing, fully ambidextrous controls, and FN’s cold hammer-forged barrel for long-term durability. The pistol balances shootability and reliability, with a trigger that’s consistent and predictable under stress. The mounted Vortex Viper optic adds fast target acquisition without permanently modifying the slide.

This package includes two magazines and represents a solid value for anyone looking to step into an optics-ready platform backed by FN’s reputation for rugged service pistols.
