ProMag COL30 1911 Government 8-Round .45 ACP Magazine Black Steel

The ProMag COL30 delivers reliable feeding and extended capacity for 1911 Government models chambered in .45 ACP. This 8-round magazine provides shooters with one additional round compared to standard 7-round factory magazines while maintaining the proven reliability expected from quality aftermarket components.

What Makes This Different

Unlike standard capacity magazines, the COL30 extends overall length minimally while adding crucial extra capacity. The black steel construction resists corrosion better than blued finishes, while the heat-treated spring maintains consistent tension through thousands of loading cycles. ProMag's manufacturing process includes rigorous testing to ensure reliable feeding with both ball and hollow point ammunition.
