PISTOL: FN HERSTAL FIREARMS MODEL FN 509C, SERIAL NUMBER GKS0139590, BLACK (MATTE), NOT INCLUDED, 3.25, 9MM PARABELLUM, SEMI - AUTOMATIC Notes: FN 509 in 9x19 with the threaded barrel and optics cut slide. The frame is marked FN, COLUMBIA, SC USA and the slide carries the FN oval, 509 and 9x19. Black finish throughout, with the factory knurled thread protector fitted over the 1/2x28 muzzle threads. This is the tactical configuration of FN's duty gun and it is set up the way a serious user actually builds one. FN's Low Profile Optics Mounting System means the dot sits down low on the slide rather than perched on an adapter, and it runs tall suppressor height iron sights marked Trijicon front and rear, so the irons co-witness under the dot instead of disappearing beneath it. Thread the muzzle for a can or a comp and the sights still work. It comes wearing two pieces of glass and light that are worth real money on their own: SIG Sauer red dot mounted on the slide, with a protective hood fitted. Olight Baldr RL Mini, a combined weapon light and red laser, on the frame rail. The laser has windage and elevation adjustment screws on the body. Condition is very good. The finish is clean with only light handling marks, the slide serrations and controls are sharp, the optic glass is clear and the thread protector is undamaged. The factory red chamber flag is fitted in the photographs. Photographed as it is, so please look the pictures over and judge for yourself. Sold with the red dot, the Olight Baldr RL Mini and the thread protector as pictured.
