FN 509 Midsize Handgun Magazine Black 9mm Luger 15/rd

The FN 509 Midsize Handgun Magazine in Black 9mm Luger is a factory-original magazine designed specifically for the FN 509 Midsize pistol platform. This genuine FN USA OEM component (MPN 20-100348) ensures dimensional precision and reliability that match the firearm's original tolerances and feeding geometry. Having multiple factory magazines on hand is essential for uninterrupted range sessions and operational readiness.

Constructed to FN's factory specifications, the magazine features a proven feed-lip geometry and spring assembly tuned to the 9mm Luger cartridge's dimensional standards. The magazine has a capacity of 15 rounds, which is the standard configuration for the FN 509 Midsize platform, balancing magazine bulk with adequate ammunition load for defensive encounters and training exercises. The black finish resists corrosion under typical carry and storage conditions.

This magazine suits shooters who own the FN 509 Midsize and need spare ammunition storage for range training, qualification requirements, or duty rotation cycling. At 0.23 lbs per magazine and compact external dimensions (2.75 x 1.38 x 6.5 inches), it remains practical for duty belts, range bags, and tactical load-outs without excessive weight accumulation across multiple magazines. Serious practitioners understand that multiple factory magazines are crucial for maintaining operational efficiency.
