The EAA Witness 9mm 10-round compensator steel magazine is a factory-original replacement magazine engineered for the Witness platform. This is a genuine EAA part designed to restore or expand magazine capacity for shooters relying on the Witness in 9mm Parabellum. The all-steel construction and controlled feed geometry ensure consistent chambering and reliable extraction across extended shooting sessions, whether during qualification drills, range training, or duty carry scenarios.
At 10 rounds, this magazine meets capacity restrictions in jurisdictions with magazine-limit regulations while maintaining the mechanical reliability users expect from steel-bodied ammunition storage. The compact footprint—measuring 2.5 x 0.75 x 4.5 inches and weighing just 0.25 lbs—integrates cleanly with the Witness platform without excessive heel or protrusion. Steel body construction resists impact deformation and corrosion better than polymer alternatives, a practical advantage in high-round-count training sessions or demanding field conditions.
This magazine serves operators, sport shooters, and civilian carriers using the Witness 9mm who need factory-spec replacement or secondary magazines. It's particularly valuable for shooters in states or jurisdictions with 10-round magazine limits seeking genuine OEM parts rather than aftermarket alternatives. Having multiple magazines reduces reload downtime, supports transition to fresh springs, and ensures mission-critical function when primary magazines are in maintenance rotation.
The EAA Witness platform has maintained a presence in law enforcement academies and civilian defense training for decades, and genuine OEM magazines are the gold standard for ensuring zero compatibility surprises. Unlike universal or cross-platform magazines, this factory-original part guarantees correct feed angle, spring tension, and witness holes aligned to the Witness frame.
