FN 509M Tactical Pistol, 9mm, FDE, Optic Ready, 5×10-Round

The FN 509M Tactical pistol in 9mm with a flat dark earth finish and 10+1 capacity (brand part no. 66-101710) is a midsize, optic-and-suppressor-ready pistol built for concealed carry, home defense, and duty use, shipping with five 10-round magazines for restricted-capacity markets. FN America cold hammer-forges the 4.5-inch stainless steel barrel with a 1/2×28 thread pattern, and FN’s low-profile optics-mounting system adds most major red dots in minutes. Suppressor-height 3-dot night sights co-witness with a mounted optic, and two interchangeable backstraps let shooters dial in grip fit. Among restricted-capacity semi-auto handguns, this 509M Tactical FDE configuration favors shooters in capacity-limited markets who still want a full magazine supply.
