Description
The FN 509 CC Edge is a purpose-built carry pistol, and FN built its magazines to match that level of intent. This 15-round factory magazine is the same design that ships with the 509 CC Edge from the factory, so you know exactly what you're getting in terms of fit and function.
The body is built from durable steel and features a high-visibility anti-tilt follower that promotes consistent cartridge alignment and smooth feeding round after round. Witness holes are machined into the body so you can get a quick visual round count without having to count on memory or feel. The gray machined aluminum base pad is a standout feature — aluminum is significantly more rigid than polymer, and the added weight means an empty magazine will drop free from the grip frame reliably, which matters when you're pushing for a fast reload under pressure.
The graphite-anodized gray finish on the base pad ties in directly with the CC Edge's black and graphite two-tone aesthetic, so it looks at home on the gun instead of like an afterthought. That's the kind of detail that makes FN's Edge Series magazines worth having over generic alternatives.
This mag is worth picking up as a dedicated spare for range training, a backup for your carry rotation, or simply to have on hand so you're not down to one magazine if something happens to your factory-issue mags. The 509 CC Edge platform is built around the idea that every component should perform at a high level, and the magazines are no exception.

Frequently Asked Questions
Will this FN 509 CC Edge magazine fit any other FN 509 models?
This magazine is designed and designated specifically for the FN 509 CC Edge. Some users have reported it also fits the standard FN 509 Compact, but FN lists it as compatible with the CC Edge platform. If you are running a different 509 variant, double-check compatibility before ordering.
Why does this magazine have an aluminum base pad instead of polymer?
The machined aluminum base pad serves two practical purposes. First, it adds enough weight at the bottom of the magazine to ensure a clean, reliable drop-free release when the mag is empty, which speeds up reloads. Second, aluminum is more rigid than polymer and provides a more positive surface for seating the magazine and for stripping it in a malfunction situation.
Is this a factory FN magazine or an aftermarket product?
This is a genuine OEM magazine made by FN America, with the manufacturer part number 20-100656. It is the same magazine design that ships with the FN 509 CC Edge pistol from the factory, not a third-party alternative.
Does the gray finish on this magazine match the FN 509 CC Edge pistol?
Yes. The 509 CC Edge has a black and graphite gray two-tone finish, and the gray anodized aluminum base pad on this magazine is designed to complement that color scheme. It looks intentional and at home on the gun rather than mismatched.
How do I know when the magazine is getting low on rounds?
The magazine body has machined witness holes that let you visually check your round count at a glance without needing to remove the magazine from the gun. The high-visibility follower also makes it easy to spot when you are running low.
