The ProMag FNHA8 magazine delivers reliable feeding and extended capacity for FN FNX pistols chambered in .45 ACP. This aftermarket magazine provides shooters with a cost-effective alternative to factory magazines while maintaining consistent performance across extended shooting sessions.

What Makes This Different

Constructed from heat-treated blued steel, the FNHA8 offers enhanced durability compared to polymer alternatives. The 20-round capacity extends shooting time between reloads, particularly beneficial during training sessions or competitive events. ProMag's spring tension system ensures consistent cartridge presentation to the chamber, reducing feeding issues common in extended-capacity magazines.
