The Mec-Gar MGCG4510N delivers reliable feeding and extended capacity for 1911 Government models chambered in .45 ACP. This 10-round magazine extends beyond standard 7-8 round capacities while maintaining the proven reliability that has made Mec-Gar the OEM supplier for major firearm manufacturers worldwide.
What Makes This Different
Unlike standard flush-fit magazines, this extended design provides three additional rounds without compromising reliability or requiring modifications to the pistol. The nickel-plated carbon steel construction resists corrosion better than blued finishes while providing smooth feeding cycles. Mec-Gar's proprietary spring system maintains consistent tension across the extended capacity range, ensuring reliable feeding from first round to last.
