Pro Mag FN 509 Compact 9mm Luger 12-Rd Blue Steel Magazine

The Pro Mag FNH-A11 is a 12-round aftermarket replacement magazine built for the FN 509 Compact 9mm Luger pistol. Its heat-treated high-carbon steel body wears a corrosion-resistant blued finish for long service life, and the precision-wound spring with injection-molded follower delivers consistent feeding in the compact grip frame.

Designed as a dedicated spare or backup for the FN 509 Compact, this blue steel magazine provides extra capacity over flush-fit magazines while keeping a low profile. The FNH-A11 is a no-frills 9mm Luger option made for range training, defensive use, or competition practice.
