Description
The Mec-Gar MGCG45082A is a standard replacement magazine built for full-size 1911 Government pistols chambered in .45 ACP. It holds 8 rounds and features a carbon steel tube that's been heat-treated for strength and durability. The blued finish pairs with the laser-engraved 2nd Amendment text that runs along the magazine body.
Internally, this magazine uses a self-lubricating nylon polymer follower with a metal insert where the slide stop engages. This design ensures proper alignment and reliable feeding of different ammunition types. The phosphate-coated high-tensile music wire spring is built to last through countless loading cycles, while the removable high-impact polymer floor plate is tapered to fit funneled and flared magwells. The magazine also includes numbered witness holes so you can count rounds at a glance.
Mec-Gar has been manufacturing magazines in Italy since 1965 and produces magazines for major firearm manufacturers worldwide. This magazine is no exception—it's engineered to strict tolerances and designed to function flawlessly in standard Government-model 1911s. It works equally well as a spare mag for the range or for defensive use. Keep in mind that new magazines come with stiff springs and may require a break-in period before they load to full capacity easily.

Frequently Asked Questions
Will this magazine fit my specific 1911 model?
This magazine is designed for 1911 Government-size pistols, including Colt and most clones. That said, some aftermarket magwells with tight tapers might not accommodate the polymer floor plate since it flares slightly wider than the magazine tube. If you have a Kimber or Springfield with a precision-fit magwell, test fit first or contact the manufacturer to verify compatibility.
Does the spring need a break-in period?
Yes. New magazines often come with stiff springs that make loading to full capacity difficult until they're broken in through use. After a few range trips or loading sessions, the spring will loosen up and load more smoothly. This is normal and doesn't indicate a defect.
How reliable are Mec-Gar magazines?
Mec-Gar manufactures magazines for many major firearm manufacturers as OEM suppliers, so the reliability is proven. Customer feedback consistently reports flawless feeding and reliable function across different 1911 platforms. The heat-treated steel construction and phosphate-coated spring are built to handle thousands of cycles.
What are the witness holes on the magazine?
The numbered witness holes are small openings drilled through the magazine tube on one side. They let you see and count how many rounds are loaded without removing the magazine from your gun or opening it up. This is helpful at the range or in any situation where you need a quick round count.
Can I take this magazine apart to clean it?
Yes. The floor plate is removable, and the internal components are linked together for easy disassembly. This makes cleaning and maintenance straightforward compared to some other designs. Just be careful when reinstalling the spring and follower to ensure they're properly seated.
Is the 2nd Amendment engraving deep or will it wear off?
The text is laser engraved into the magazine body, so it's a permanent marking that won't wear off from normal use. The engraving is cosmetic and doesn't affect the magazine's function or durability.
