The FN 509 Compact Tactical pistol in 9mm and black (brand part no. 66-100783) pairs a threaded barrel with a low-profile optics mounting system, giving shooters a compact platform ready for a suppressor and a red dot at the same time. FN America / FN Herstal builds the pistol with a 4.3-inch cold hammer forged barrel and fixed 3-dot night sights set to suppressor height, and the pistol ships with two 10-round magazines. An ambidextrous magazine release and slide stop lever support use by left- and right-handed shooters, and a double-action-only trigger keeps the pull consistent shot to shot. Among threaded-barrel semi-auto handguns, this 509 Compact Tactical configuration favors shooters who want suppressor and optic compatibility in one compact build.
