Description
When it comes to magazines for a pistol you actually rely on, factory is hard to beat. This is a genuine OEM magazine from FN America, built specifically for the FNX-45 platform in .45 ACP. It holds 10 rounds and fits the pistol the way it was designed to, with no fitting, no guesswork, and no break-in period required.
The body is constructed from stainless steel with a tumble-polished finish, which gives it solid durability without adding unnecessary weight. Inside, a low-friction follower keeps rounds moving smoothly toward the chamber, helping prevent the kind of feeding hiccups that can show up with cheaper aftermarket mags. The Flat Dark Earth polymer basepad adds a nice touch for anyone running an FDE or two-tone setup, and it doubles as a comfortable surface for a positive mag seating during reloads.
The 10-round capacity makes this a go-to option for range training and reload drills, and it's a natural fit for anyone who wants to build up a small rotation of quality spare magazines. Whether you're running the standard FNX-45 or the Tactical variant, this magazine drops right in without any issues.
FN has a well-earned reputation for making their own accessories to the same tolerances as the firearms themselves, and this magazine is no exception. It's a straightforward, well-built piece of kit that does exactly what it's supposed to do.

Frequently Asked Questions
Will this magazine fit the FNX-45 Tactical, or just the standard model?
This magazine is compatible with both the standard FNX-45 and the FNX-45 Tactical. They share the same magwell and feed system, so either variant will accept it without any modification.
Is this a genuine FN factory magazine or a third-party reproduction?
This is a genuine OEM magazine made by FN America, not an aftermarket copy. It's built to the same specs and tolerances as the magazine that came with your pistol, which matters a lot when it comes to reliable feeding in .45 ACP.
Why does the FNX-45 also come in a 15-round version? What's the difference?
The FNX-45 platform offers both 10-round and 15-round magazines. The 10-round version uses a shorter basepad configuration, while the 15-rounder extends capacity with a longer tube and basepad. The 10-round is a popular choice for range use, training rotations, and areas where capacity restrictions apply.
Will the FDE basepad match my FNX-45's finish?
The FDE polymer basepad is designed to complement FN's own FDE-finished pistols and accessories. That said, FDE can vary slightly between manufacturers and product lines, so it may not be a perfect color match to every accessory out there, but it pairs well with FN's own FDE components.
How many of these magazines should I keep on hand?
Most experienced pistol owners recommend running at least three magazines per pistol, giving you a comfortable rotation for range sessions without constantly reloading the same mag. Having a few of these stocked also gives you a backup in case one gets damaged or worn over time.
Does the low-friction follower actually make a difference?
It does, especially with a cartridge like .45 ACP where reliable feeding is critical. A low-friction follower reduces drag as rounds feed up under spring pressure, which helps keep feeding consistent through the full capacity of the magazine, from the first round to the last.
