The FN 509 is a full-size 9mm striker-fired pistol designed for dependable everyday use. Its cold hammer forged stainless steel barrel supports consistent service life, while the polymer frame incorporates interchangeable backstraps to help users tailor the grip shape and reach. Fixed 3-dot sights provide a clear conventional sight picture, and the fully ambidextrous controls accommodate left- and right-handed operation. This no-manual-safety configuration uses a factory trigger safety and accepts 10-round magazines for jurisdictions with capacity restrictions.
The FN 509 combines durable construction, adaptable ergonomics, and ambidextrous handling in a practical full-size 9mm pistol.
