FN | FN 509 Compact | 9mm | Black

The FN 509 Compact trims the full‑size 509 down to a 3.7‑inch barrel and 25.5‑ounce weight while still accepting every higher‑capacity 509 magazine -⁠- genuine full‑size firepower available in a compact‑carry package when you want it. FN's Low‑Profile Optics‑Mounting System accepts nearly all commercial red dots directly, with blackout iron sights that co‑witness underneath, and improved backstrap texturing plus a flatter‑faced trigger give real, tangible control improvements over the original 509. Built for shooters who want a genuinely concealable pistol without giving up the 509 platform's full‑size performance.
