FN 20100719 510 Replacement Magazine 15rd Flush 10mm Auto Fits FN 510 Tactical Stainless/Black Stainless Steel

The FN 510 Tactical 10mm Auto 15-round replacement magazine pairs serious stopping power with reliable feeding. Built from nickel stainless steel, this mag is engineered to withstand the pressures of a heavy-hitting 10mm cartridge and the wear of regular use. Whether you're carrying a 510 Tactical for personal defense or feeding it at the range, a quality OEM magazine is non-negotiable—and FN's own design ensures feed reliability and longevity you can trust.

10mm shooters know the caliber demands respect and precision across every component. This FN magazine delivers the same exacting standards as the pistol itself, with a durable stainless steel body that resists corrosion and maintains its integrity through thousands of rounds. The 15-round capacity gives you the firepower the 10mm platform is known for, while the witness holes along the back let you check your round count at a glance without unloading.

Spare magazines are essential—whether you're building a backup stack, replacing a worn feeder, or simply ensuring you have capacity on hand. FN's replacement mags are direct-fit and function-proven in their own platform, so you're buying the same level of engineering that goes into the firearm.
