FN 20100720 545 Replacement Magazine 15rd 45 ACP, Stainless Steel with Black Polymer Flush Floorplate, Fits FN 545 Tactical

The FN 545 Tactical 15rd magazine in 45 ACP is a genuine OEM replacement mag built to FN America's exacting standards. If you run an FN 545 and need a reliable spare or replacement magazine, this stainless steel unit delivers the durability and fit that factory-engineered components provide. The nickel-coated body resists corrosion, and the black polymer flush floorplate keeps your carry profile clean while maintaining a full 15-round capacity.

FN America's manufacturing reputation stems from decades of military and law enforcement supply — the same precision that goes into their firearms extends to their magazines. This isn't a budget aftermarket clone; it's the magazine your FN 545 was designed to run. Whether you're building a backup magazine rotation, replacing worn followers, or ensuring you have a reliable spare at the range, an OEM magazine eliminates compatibility guesswork and maintains the original performance envelope your firearm was tuned for.

Magazines are wear items. Springs compress, feed lips can suffer damage on hard drops, and followers wear over time. Having an extra FN-spec magazine in the rotation extends the life of your duty rotation and ensures you're never caught short on magazine reliability when it matters.
