ProMag HECA16 32-Round 9mm Magazine for H&K VP9 - Blued Steel

The ProMag HECA16 extends H&K VP9 capacity to 32 rounds of 9mm Luger ammunition, delivering extended shooting sessions without frequent reloads. This high-capacity magazine features blued steel construction for enhanced durability compared to polymer alternatives.

What Makes This Different

The HECA16 more than doubles standard VP9 magazine capacity while maintaining reliable feeding geometry. Heat-treated steel construction resists deformation under spring pressure that can affect polymer magazines over time. The extended body design incorporates reinforced feed lips and a heat-treated spring rated for thousands of compression cycles.

Key Features

• 32-round capacity extends shooting time between reloads
• Blued steel construction provides superior durability over polymer
• Heat-treated magazine spring maintains consistent tension
• Reinforced feed lips prevent ammunition misfeeds
• Extended baseplate offers improved grip during magazine changes
• Compatible with all H&K VP9 variants and generations
• Witness holes allow visual ammunition count verification

Range sessions benefit from reduced reload frequency, while competitive shooters appreciate the extended capacity for stage completion without tactical reloads. The steel construction handles repeated loading and unloading better than polymer alternatives. Law enforcement and security professionals value the additional ammunition capacity during extended operations.
