FN 509C Tactical Pistol, 9mm, FDE, 10+1

The FN 509C Tactical pistol in 9mm with a 10+1 capacity and FDE finish (brand part no. 66-100781) is a compact, optic-ready striker-fired pistol built for concealed carry and duty use in a desert-tan colorway. FN America machines the slide with an optic cut and serrations for direct red dot mounting, and suppressor-height night sights co-witness with a mounted optic for fast target transitions. A loaded chamber indicator adds a visual and tactile safety check, and two 10-round magazines ship with the pistol.
