FN 509 Magazine 24-Round 9mm Luger Black Steel Extended Mag

The FN 509 24-round magazine extends your pistol's capacity beyond the standard 17-round configuration, providing tactical advantages in competitive shooting and defensive applications. This factory FN magazine maintains the reliability and feeding consistency that FN 509 pistols are known for. Extended capacity magazines reduce reload frequency during training sessions and competition stages.

What Makes This Different

Factory FN magazines undergo the same quality control standards as the pistols themselves, ensuring consistent feeding geometry and spring tension. Unlike aftermarket alternatives that may cause feeding issues, this magazine features FN's proven follower design and spring system. The extended baseplate adds 7 additional rounds while maintaining a manageable profile that doesn't significantly impact concealment or handling.
