The Mec-Gar MGCGOV10B delivers reliable feeding and extended capacity for 1911 Government models chambered in 10mm Auto. This factory-specification magazine addresses the common issue of limited ammunition capacity while maintaining the proven reliability that competitive shooters and law enforcement professionals demand.

What Makes This Different

Mec-Gar's proprietary spring technology and heat-treated steel construction provide consistent feeding pressure throughout the magazine's capacity range. The blued finish offers superior corrosion resistance compared to standard phosphate coatings, while the welded tube construction eliminates the weak points found in rolled-seam magazines. Independent testing shows Mec-Gar magazines maintain 98% feed reliability after 10,000 loading cycles.
