ProMag FNHA2 30-Round Magazine 5.7x28mm FN Five-seveN Polymer

The ProMag FNHA2 extends your FN Five-seveN's capacity to 30 rounds of 5.7x28mm ammunition, delivering triple the firepower of standard magazines. This extended magazine transforms the Five-seveN platform into a high-capacity option for competitive shooting and tactical applications.

What Makes This Different

Constructed from DuPont Zytel polymer, this magazine offers superior chemical resistance and dimensional stability compared to standard thermoplastics. The 30-round capacity significantly exceeds the Five-seveN's standard 20-round magazines, providing 50% more ammunition without requiring a reload. The polymer construction reduces weight by approximately 15% compared to steel alternatives while maintaining structural integrity under repeated loading cycles.

Key Features

• 30-round capacity for 5.7x28mm ammunition - 50% more than standard magazines
• DuPont Zytel polymer construction for chemical resistance and durability
• Direct drop-in compatibility with FN Five-seveN pistols
• Lightweight design reduces carry weight compared to steel magazines
• Standard magazine release compatibility - no modifications required
• Black finish matches factory Five-seveN aesthetics
• Heat-treated steel spring for consistent feeding pressure

This extended magazine excels in competitive shooting disciplines where capacity matters, particularly in action pistol competitions and tactical matches. The 5.7x28mm cartridge's flat trajectory and minimal recoil combine with the increased capacity for sustained accuracy during rapid-fire sequences. The polymer construction withstands temperature extremes from -20°F to 140°F without dimensional changes that could affect feeding reliability.
