ProMag FN 509 Compact 9mm Luger 15-Round Blued Steel Magazine

The ProMag FN 509 Compact magazine is a 15-round 9mm Luger replacement magazine purpose-built for the FN 509 Compact pistol. The magazine body is constructed of high-carbon, heat-treated steel with a corrosion-resistant blued (black oxide) finish and TIG-welded seams for long service life under hard use.

Internally, the magazine uses an injection-molded polymer follower paired with a heat-treated chrome silicon wire spring to deliver consistent feeding round after round. Precision-machined feed lips keep each cartridge properly aligned under spring tension. Designed and made in the USA to ProMag's quality standards, this blued steel magazine is a reliable factory-pattern spare or replacement for your FN 509 Compact carry or range pistol.
