The FN 509 Tactical pistol in 9mm with a 10+1 capacity and black finish (brand part no. 66100527) is a full-size, threaded-barrel striker-fired pistol built for suppressor compatibility and duty use. FN America cold hammer-forges the 4.5-inch stainless steel barrel with a 1/2×28 thread pattern, and suppressor-height Trijicon 3-dot green tritium night sights clear a mounted suppressor for co-witness aiming. FN’s low-profile optics-mounting system accepts most major red dots, and a sight-protecting slide cap guards the rear sight during optic swaps. Two interchangeable backstraps and a full ambidextrous control set round out the package, with a soft pistol case included. Among threaded-barrel semi-auto handguns, this 509 Tactical black configuration favors suppressor-focused duty and range shooters.
