FN 509 Tactical Pistol, 9mm, FDE, 17+1, Threaded

The FN 509 Tactical pistol in FDE with a 4.5-inch threaded barrel and 17-round capacity (brand part no. 66-100373) is a duty-grade 9mm built for suppressor use. FN America adds front slide serrations for easier press-checks, and 3-dot night suppressor-height sights co-witness with a mounted can or optic. This configuration ships without a manual safety, relying on the striker-fired action, and includes both a 24-round and a 17-round magazine. Among threaded-barrel semi-auto handguns, this 509 Tactical configuration favors shooters who want suppressor compatibility in a distinct FDE finish.
