HK VP9SK/P30SK 12-Round Extended Magazine 9mm Luger Black Steel

The HK VP9SK/P30SK 12-round extended magazine transforms compact pistols into higher-capacity platforms without sacrificing concealability. This factory magazine extends grip length by approximately 0.75 inches while maintaining the reliability standards expected from Heckler & Koch components.

What Makes This Different

Factory HK magazines feature precision-engineered steel construction with witness holes for round counting and anti-tilt followers that prevent feeding malfunctions. The extended baseplate adds 2 additional rounds over standard 10-round magazines while providing enhanced grip purchase. Unlike aftermarket alternatives, these magazines undergo the same rigorous testing protocols as original equipment, ensuring consistent feeding geometry and spring tension.

Key Features

• 12-round capacity increases firepower by 20% over standard magazines
• Steel construction with corrosion-resistant black finish withstands 50,000+ loading cycles
• Anti-tilt follower design eliminates double-feeds and misfeeds
• Witness holes allow quick visual ammunition counts in low-light conditions
• Extended baseplate provides additional grip surface for enhanced control
• Drop-free design ensures reliable tactical reloads under stress

Law enforcement agencies report 99.8% reliability rates with factory HK magazines during qualification courses. The extended configuration proves particularly effective for plainclothes officers requiring additional capacity without printing through clothing. Competition shooters benefit from the improved grip purchase during rapid strings of fire, while the steel construction maintains consistent spring pressure through extended practice sessions.
