The FN FNX 45 ACP pistol magazine is purpose-built for shooters who demand factory-level reliability in their 45 ACP platform. This 10-round magazine pairs FN's commitment to quality with thoughtful design details that make it equally useful at the range, in competition, or as a duty backup. Built with stainless steel construction and engineered to the exacting standards FN applies to every component, these magazines are the OEM choice for FNX-45 owners who refuse to compromise on feeding reliability.

The magazine body is stainless steel with a matching stainless finish, paired with a polymer floorplate and follower that work together to provide smooth feeding and easy disassembly for cleaning. The large polymer floorplate isn't just a grip aid—it's genuinely useful when you're fishing a magazine out of a tight retention holster or pouch under stress. And the round count witness holes on the rear let you visually check your capacity at a glance without removing the magazine from your pouches or pack.

If you run an FNX-45, going factory FN is the move. You know the gun, you trust the platform, and a magazine should never be the weak link. This is the mag that FN built for the pistol; it's the same one that ships in the box. Grab a spare or two.
