Promag FN 509 Compact 9mm 12-Round Blue Steel Magazine

The ProMag® FN® 509 Compact 9mm 12-Round Blue Steel Magazine is an economy-priced, aftermarket pistol magazine, engineered to deliver butter-smooth feeding and consistent operation at a fraction of the cost of factory FN magazines. The heat-treated steel body delivers exceptional strength and crush-proof performance, while the premium blued finish offers superior corrosion resistance for reliable field operation in virtually any environment. A heat-treated chrome silicon wire internal spring works in tandem with the durable, injection-molded polymer follower for consistent alignment and reliable feeding, while the removable floor plate allows for quick disassembly when maintenance and cleaning are required. Better yet, this magazine is backed by ProMag’s legendary lifetime warranty, offering years of reliable field service and superior quality you can depend on when it matters most. Made in USA.
