ProMag FNHA13 9mm 20rd Blued Steel Magazine for FN 509

The ProMag FNHA13 is a high-capacity 20-round detachable replacement magazine built specifically for the FN 509 family of 9mm service pistols. Designed as a dependable spare or training magazine, it matches factory form factor for reliable fit and feeding on the range or in duty use.

Proudly Made in the USA by ProMag Industries, the FNHA13 is the right call for topping off your FN 509 kit with extra capacity for training, competition, home defense, or a duty rotation.
