The ProMag FNX-45 .45 ACP 15-round steel blue magazine is a straightforward, American-made reload solution for FN FNX-45 pistol owners. Built from heat-treated carbon steel with a black oxide finish, this magazine delivers the durability and reliability you'd expect from a factory-style alternative. Whether you're running drills at the range, preparing for duty use, or stocking up on spares, a robust 15-round mag keeps your shooting sessions uninterrupted and your firearm ready.
ProMag engineered this magazine with practical longevity in mind. The heat-treated carbon steel body resists wear and corrosion through regular handling and cleaning, while the black oxide finish provides corrosion protection without added bulk. The injection-molded follower and heat-treated chrome silicone wire spring work together to feed rounds reliably, cycle after cycle. Made in the USA, this magazine represents solid value for shooters who need dependable capacity without paying premium pricing.
FNX-45 users appreciate having multiple magazines on hand for training, competition, or defensive readiness. A spare magazine also gives you a backup if your primary mag wears out or gets damaged. At 15 rounds, you get the full capacity of the FNX-45 platform, matching what the pistol was designed to run.

Yes. This ProMag magazine is engineered to fit and function in the FNX-45 .45 ACP pistol and holds 15 rounds—the full design capacity of that platform.
ProMag magazines are aftermarket alternatives to OEM mags. This one uses the same heat-treated carbon steel and black oxide finish, plus a molded follower and chrome silicone spring. They perform the same function at a lower cost per unit, making them popular for training and backup use.
Black oxide provides solid corrosion resistance for regular use and cleaning. Over time with heavy handling, the finish may show wear, but the underlying steel remains protected. The heat-treated steel body itself is engineered to withstand repeated loading, unloading, and insertion into the magazine well.
Yes, ProMag manufactures this magazine in the United States.
