FN doesn't cut corners on their factory magazines, and this one is no different. The 509 10-round FDE mag is built with a steel body, a heat-treated wire spring, and a low-friction polymer follower that keeps rounds feeding cleanly and consistently. The anti-tilt follower also lines up with the witness holes on the back of the magazine, so you can get a quick round count at a glance. The FDE polymer baseplate sits flush with the magwell for a clean profile, and it's removable for easy disassembly when you want to clean or inspect the internals.
Being a genuine OEM FN product, this magazine is manufactured to the same specifications and tolerances as what came with your pistol. That matters more than people sometimes realize. Fit, feed geometry, and spring tension are all dialed in for the 509 platform specifically, so you're not crossing your fingers hoping a third-party mag runs right.
The 10-round capacity makes this one particularly useful for FN 509 owners who want a lighter, trimmer carry setup, or anyone who needs a mag that works for range training alongside higher-capacity mags. It's worth noting that this magazine is designed for the full-size FN 509 and will not fit the FNS or FNX series pistols. If you're running a 509 Midsize or Compact, a separate sleeve is required for use with this mag and is not included.
The two-tone finish, black steel body with the FDE baseplate, looks sharp and holds up well. If you've got an FDE 509, this is the mag that matches. Picking up a couple of extras just makes good sense whether you're building out a range kit or stocking a spare for your carry gun.
This magazine is designed for the full-size FN 509. It can be used with the 509 Midsize or Compact, but only with a separately purchased sleeve that is not included with this magazine. Make sure to grab the correct adapter if you are running one of the compact variants.
No, this magazine is not compatible with the FNS or FNX series pistols. It is purpose-built for the FN 509 platform only. If you own an FNS or FNX, you will need a magazine specifically designed for those models.
This is a genuine OEM magazine manufactured by FN America to the same specifications and tolerances as the magazines that ship with the FN 509 from the factory. You are getting the real thing, not a third-party substitute.
There are a few good reasons. Some people prefer the slightly lighter and trimmer feel of a 10-round mag for everyday carry, while others use them specifically for range training drills that require a limited round count. It is also a practical option for anyone who wants a factory flush-fit magazine for their 509.
The FDE polymer baseplate is removable, which allows you to fully disassemble the magazine for cleaning and inspection. Regular maintenance of your magazines is a good habit, especially if they see a lot of range use or are part of a carry rotation.
Yes, FN designs the FDE accessories to coordinate with the FDE pistol finish. The FDE baseplate on this magazine is a solid visual match for FDE-configured FN 509 pistols, giving your setup a consistent look.
