The Mec-Gar Government magazine has been trusted by military and law enforcement worldwide for decades. This stainless steel construction holds 8 rounds of .45 ACP and is built with a lubricated nylon polymer follower that includes a metal insert where the slide stop engages, ensuring reliable slide lock and consistent feeding.
The tube is made from heat-treated carbon steel coated in stainless finish, paired with a high-tensile music wire spring that maintains tension through thousands of cycles. The removable polymer baseplate is designed with a tapered fit to work smoothly with funneled magazine wells. This combination of materials and design keeps the magazine feeding reliably whether you're running full metal jacket rounds or defensive loads.
Mec-Gar has been manufacturing magazines since 1965 and supplies OEM magazines to major firearm companies worldwide. That industrial-grade quality translates to the aftermarket magazines as well. The follower design keeps rounds properly aligned in the magazine body, which matters more than people realize when it comes to feeding reliability. The spring won't lose its tension after being loaded for extended periods, and the stainless finish resists corrosion if your mag spends time in a range bag.
This magazine is purpose-built for full-size 1911 Government models in .45 ACP. Standard single-stack 1911 magazines are generally interchangeable across makes and models of full-size pistols, though individual guns can be picky about which mags they prefer. It's worth testing your new magazine at the range to confirm it locks back reliably on the last round and feeds smoothly with your specific 1911.
Standard 1911 Government magazines are generally interchangeable across full-size 1911 models from different manufacturers. However, individual guns can be finicky about magazine preferences. The best approach is to load a few rounds and test it for reliable feeding and proper slide lock at the range. If you notice any issues, try one round less or test with different ammunition types to rule out a feeding problem.
Stainless steel offers superior corrosion resistance, making it a solid choice if your magazines spend time in a range bag or get exposed to moisture. The natural silver finish also pairs well with many 1911s. Mec-Gar offers this mag in blued and nickel options too, so pick whichever finish matches your pistol's appearance and meets your durability needs.
While this magazine is engineered for 8 rounds, some experienced 1911 shooters load only 7 for maximum feeding reliability and to ensure the slide locks back consistently on the last round. Many shooters also load one in the chamber and seven in the magazine for a total of 8. Your gun's preferences may vary, so test different loading levels to see what works best with your 1911.
Mec-Gar magazines are designed to handle thousands of cycles without degradation. The high-tensile music wire spring resists fatigue better than lower-quality springs. With normal use and storage, you can expect this magazine to perform reliably for years. Avoid overloading or leaving the magazine fully loaded indefinitely in hot conditions, as extreme heat can eventually affect spring tension.
