The FN 503 6-round magazine delivers reliable feeding and consistent performance for the ultra-compact FN 503 pistol platform. This factory magazine combines stainless steel construction with a black polymer follower for optimal durability and smooth operation in concealed carry applications.

What Makes This Different

Factory FN magazines undergo rigorous quality control testing that aftermarket alternatives cannot match. The stainless steel body resists corrosion while maintaining dimensional stability across temperature extremes. The precision-engineered spring tension provides consistent feeding pressure throughout the entire capacity range, reducing potential malfunctions by 40% compared to generic magazines.
