FN FNX-45 Magazine 10-Round .45 ACP Black Stainless Steel

The FN FNX-45 10-round magazine delivers reliable feeding and consistent performance for one of the most respected striker-fired pistols in the .45 ACP platform. This factory magazine features stainless steel construction with a black polymer follower and baseplate for enhanced durability and corrosion resistance.

What Makes This Different

Factory FN magazines undergo rigorous quality control testing that aftermarket alternatives often skip. The stainless steel body resists deformation under stress while the precision-molded polymer components ensure smooth feeding cycles. Unlike generic magazines, this unit maintains the exact spring tension and geometry specifications that FN engineers designed for optimal reliability.
