Description
When your carry gun is a FN Reflex, the last thing you want is a questionable aftermarket magazine in the mix. This is the factory OEM magazine straight from FN America, chambered for 9mm Luger and built to the exact same spec as the one your pistol shipped with. Ten rounds, flush-fit black base plate, and a fit that drops free cleanly every time.
The construction here is what you'd expect from FN. The body is stainless steel with a corrosion-resistant finish, so it holds up whether you're storing it in a range bag or carrying it as a spare every day. Inside, an anti-tilt polymer follower keeps rounds positioned correctly as the mag empties, and the reinforced feed lips work with a steel-wire spring to keep feeding smooth from the first round to the last. Rear-facing numbered witness holes let you do a quick round count at a glance, which is a small thing that's genuinely useful in a carry context.
The flush base plate keeps the profile as compact as possible, which is the whole point with a pistol designed around deep concealment. This mag sits flush with the grip and doesn't add any bulk to the package. It also fits the optics-ready FN Reflex MRD model, so if you're running either variant of the standard Reflex, you're covered.
For anyone building out their Reflex setup, a second or third magazine is just part of the equation. Whether you're rotating mags at the range, keeping one loaded in a holster, or just want a reliable backup in the safe, this is the one to grab.

Frequently Asked Questions
Will this magazine fit the FN Reflex MRD model?
Yes, this magazine is compatible with both the standard FN Reflex and the optics-ready FN Reflex MRD. The mag specs and fit are the same across both variants. It is not designed for the Reflex XL, which is a different, longer platform.
Is this a genuine FN factory magazine or an aftermarket product?
This is a genuine OEM magazine made by FN America, part number 20-100710. There are currently no aftermarket magazines produced for the FN Reflex, so factory mags are the only option available. That said, you're getting the same quality and reliability spec as the magazine your pistol came with.
Does this magazine sit flush with the grip of the Reflex?
Yes, the flush-fit black base plate is designed to sit even with the bottom of the grip, keeping the pistol as compact as possible. This makes it a great choice for carry use where keeping a low profile matters.
How do I know how many rounds are loaded without dropping the magazine?
The magazine features rear-facing numbered witness holes along the back of the body, so you can quickly check your round count without removing the mag from the gun. It's a simple but practical feature for both range use and carry.
Will the magazine drop free reliably when I hit the mag release?
FN designed these magazines with metal-bodied construction and a tilt-free follower, and they're well-regarded for dropping free cleanly without requiring any assistance. The fit is precise enough for positive retention but smooth enough for fast reloads.
Does this 10-round magazine work the same as the higher-capacity Reflex magazines?
The internal components are consistent across the FN Reflex magazine lineup, featuring the same stainless steel body, anti-tilt polymer follower, and reinforced feed lips. The 10-round version simply has a shorter tube and a flush base plate, while the 11-round version adds a finger rest and the 15-round version extends below the grip.
