ProMag FNHA7 32-Round Magazine 9mm FN 509 Blued Steel Extended

The ProMag FNHA7 delivers extended firepower for FN 509 pistols with its 32-round capacity in a robust blued steel construction. This high-capacity magazine extends your shooting sessions and reduces reload frequency during training or competition.

What Makes This Different

The FNHA7 more than doubles the standard FN 509 magazine capacity, providing 32 rounds compared to the factory 17-round magazines. The blued steel body offers superior durability over polymer alternatives, with enhanced resistance to deformation under stress. The extended length provides additional grip surface while maintaining reliable feeding through ProMag's proven spring system and follower design.

Key Features

• 32-round capacity for extended shooting without frequent reloads
• Blued steel construction resists corrosion and maintains structural integrity
• Drop-free design ensures smooth magazine changes under pressure
• Heat-treated spring maintains consistent tension through thousands of cycles
• Anti-tilt follower prevents binding and ensures reliable feeding
• Witness holes allow quick visual capacity assessment
• Extended baseplate provides secure grip during tactical reloads

The FNHA7 performs consistently across various 9mm ammunition weights from 115 to 147 grains. Competition shooters benefit from the reduced reload frequency during stages, while training applications see extended range sessions with fewer interruptions. The steel construction withstands repeated dropping on concrete and maintains dimensional stability in temperature extremes from -20°F to 140°F.
