In high-stress scenarios you want gear that feeds cleanly, resists the elements, and gets you back in the fight faster. Reliability is not glamorous, but it’s everything. We tested, handled, and inspected a purpose-built replacement magazine that brings proven materials and practical design to the FN 545 platform.
FN 545 MAGAZINE (15-ROUND) is a 15-round .45 ACP magazine made for the FN 545 series. It features a steel-body construction with a nickel-coated finish that protects against corrosion while reducing friction for faster reloads, and it ships with a black polymer baseplate. Priced at $46.79, this magazine is an affordable, duty-ready spare that complements FN pistols and similar platforms. Shop this product
Key features that matter
We break gear down into attributes you can verify in the range and on the shelf. The FN 545 MAGAZINE (15-ROUND) brings three primary features to the table:
Steel-body construction
Steel magazines offer dimensional stability and resistance to deformation under repeated stress compared to some stamped or thin-sheet alternatives. For shooters who run high-round-count practice or maintain magazines for duty use, the steel body keeps feed lips and overall shape true through heavy handling.
Nickel-coated finish
The nickel coating is more than cosmetic. It provides a corrosion-resistant barrier that helps protect the magazine from moisture, sweat, and environmental exposure. That finish also reduces friction between rounds and the magazine walls, which translates to smoother feeding and consistently faster reloads during timed drills.
Black polymer baseplate
The polymer baseplate reduces snag risk and provides a reliable interface with magazine wells and pouches. It’s a practical touch — durable without adding unnecessary weight — and facilitates easy disassembly for maintenance when needed.
Performance and practical applications
The FN 545 MAGAZINE (15-ROUND) is chambered for .45 ACP, a cartridge known for its balance of controllable recoil and proven terminal performance. That makes this magazine suitable for a range of uses: duty carry where extra rounds are valued, personal defense platforms, and recreational range time for shooters who prefer .45 ACP’s characteristics.
At 15 rounds, this magazine offers a meaningful capacity advantage over many standard double-stack options while maintaining ergonomics that pair well with the FN 545 family. The steel body and nickel finish combine to promote consistent feeding — you’ll notice less drag when performing quick reloads in drills, and the reduced friction helps maintain cadence in timed courses of fire. If you’re stocking spares for regular training, $46.79 per magazine is a competitive price point for this build quality and finish.

Compatibility, fit, and installation
This magazine is designed for the FN 545 series, and the listing identifies the model compatibility as Various — meaning it will fit the intended FN platforms built around that magazine well geometry. Always verify fit by inserting and locking the magazine into your firearm unloaded and checking lockup, release, and feeding alignment before live-fire.
Loading and break-in
New springs and followers can feel stiff; a short break-in period of standard loading cycles will seat the spring for consistent tension. Use proper loading tools if you prefer, but hand-loading to capacity while ensuring rounds seat fully against the feed lips will minimize malfunctions early on.
Range check protocol
Run a quick function check with your preferred ammunition. Load the magazine, rack the slide, run a few single-shot feeds, and perform a controlled 15-round string. Watch for feed hang-ups and verify the magazine drops cleanly on release. If anything feels off, inspect the feed lips, follower, and baseplate for defects before proceeding.
Maintenance and storage
Care for the FN 545 MAGAZINE (15-ROUND) like you would any high-quality steel magazine. Wipe the exterior nickel finish with a soft cloth after exposure to moisture or sweat. Avoid harsh abrasives that can damage the coating. Periodic disassembly to inspect the spring and follower will extend service life; replace the spring if you notice weakening or inconsistent tension.
Storage guidance
Store magazines unloaded for long-term preservation of spring life, or rotate loaded magazines if you maintain a ready set. Keep them in a dry environment and check the baseplate and body for signs of corrosion or impact damage periodically.
Why this magazine earns a spot on your kit list
Fn has a reputation for manufacturing robust service-grade components, and the FN 545 MAGAZINE (15-ROUND) follows that pedigree. The combination of steel-body durability, a nickel-coated finish for corrosion resistance and lower friction, plus the practical black polymer baseplate, makes this magazine a solid choice for shooters who demand dependable feeding and clean reloads. At $46.79, it offers an accessible way to expand capacity without compromising build quality.
