Description
This is a stripped slide for your FN 509 pistol. You will need to supply all of your own internals from your factory FN 509 slide (see below), and you will need a barrel. All spaces in the slide accept factory FN components. For optimal performance, all Apex parts for the 509 fit this slide.
Apex 5” Slide for the FN 509 Pistol
- Front and Rear Cocking Serrations – Two options available: Classic or Lightning Bolt Serrations. Provides positive grip for press checks and slide manipulation, even with wet or sandy hands common to coastal carry.
- Suppressor Height Sights – Black-on-black sights installed by Apex. These co-witness through your optic, giving you a reliable backup aiming reference without adding glare.
- Black PVD Finish – Physical Vapor Deposition coating resists corrosion from salt air, humidity, and sweat. This finish holds up to daily carry along the Florida coast without rust or wear.
- Ported Slide Design – Slide ports matching the Apex Ported Barrel for the FN 509 allow escaping gasses from the barrel ports to reduce muzzle rise. An Apex ported barrel is required for the ports to work correctly.
