The FN 509 LS Edge is a purpose-built, performance-driven pistol, and the magazine that goes with it had to meet the same standard. This is the genuine OEM 10-round magazine from FN America, made to the exact specs and tolerances of the magazines that ship with the gun. That means no guesswork on fit, no feeding quirks to troubleshoot, just the same reliability FN engineered into the platform from day one.
The body is constructed from laser-welded stainless steel and treated with a nitride finish that resists corrosion in rough conditions. The gray polymer base plate is what sets this one apart visually and functionally from standard 509 magazines. The LS Edge features a flared, graphite anodized aluminum magazine well specifically designed around these Edge-spec base plates, which is exactly why standard 509 magazines do not seat properly in the LS Edge. This is not a universal 509 mag, it was built for this gun.
Inside, a steel wire spring and hi-vis polymer follower work together to keep rounds feeding smoothly and reliably. The machined feed lips maintain tight tolerances round after round, and the removable polymer floor plate makes cleaning and maintenance quick and painless. FN also built this magazine to enhanced external geometry specs, which translates to a precise, flush fit with the LS Edge's magwell and a snag-free draw during fast reloads.
Whether you are picking up a spare to train with or restocking after putting serious rounds downrange, having an extra magazine that you know will work without a second thought is just part of running your LS Edge the right way.
No. This magazine was built exclusively for the FN 509 LS Edge. The LS Edge features a flared aluminum magwell with different geometry than other 509 models, and the base plate dimensions on these Edge-spec magazines do not seat properly in standard 509 frames. FN designed this magazine specifically around the LS Edge platform, so it is not cross-compatible with the rest of the 509 lineup.
The 509 LS Edge was designed with a flared, graphite anodized aluminum magazine well that is slightly different from the standard 509 magwell. This specialized magwell requires a magazine with matching base plate dimensions to seat and lock up correctly. FN engineered the Edge-specific magazines to take advantage of that magwell for faster, more reliable reloads under pressure.
Yes. FN confirms that the 24-round FN 509 magazine is compatible with the 509 LS Edge. This is one of the few standard 509 magazines that works in the Edge platform. For anything other than the 24-rounder, you will want to stick with magazines specifically designated for the LS Edge.
It is both. The gray polymer base plate matches the two-tone aesthetic of the FN 509 LS Edge, but more importantly, it is built to the specific dimensions required by the LS Edge's magwell. It is also removable, which makes routine cleaning and spring inspection straightforward without any tools.
The FN 509 LS Edge ships with three 10-round magazines. Picking up extras is a smart move if you spend a lot of time at the range or want dedicated training magazines that you are not cycling through your carry or duty rotation.
This is a 100% genuine OEM magazine made by FN America to the same specifications and tolerances as the magazines that come in the box with the 509 LS Edge. It carries FN's manufacturer part number 20-100479, so there is no compatibility uncertainty. FN-made magazines for the LS Edge are the benchmark for fit and function in this platform.
