Description
This is a factory Kimber compact 7-round magazine for .45 ACP 1911 pistols. The tube is laser-welded stainless steel with a corrosion-resistant black matte finish over the underlying metal, giving it real durability in the field. Unlike cheaper aftermarket options, factory Kimber magazines are engineered to the exact same specs and tolerances as the magazines that ship with your pistol, which means you get that snug fit and reliable feeding right out of the box.
Black Finish Compact 1911 Magazine Design
The steel construction throughout includes a steel wire spring and steel follower, both designed to deliver smooth, consistent feeding. The magazine features wide-cut witness holes so you can quickly count your rounds at a glance without removing the mag. The baseplate is pre-drilled and tapped, so if you want to add an extended base pad for easier magazine removal or a different look, everything's ready to go.
Compatible with Compact and Ultra Models
This magazine is designed specifically for Kimber Compact and Ultra frame sizes. It also works with Colt Officer's Models that use the same compact grip dimensions. Note that it's not compatible with Ultra+ models. One thing to know is that new factory magazines typically come with stiff springs, so the last round or two might take some pressure to seat initially. Once you load them a few times, they break in and function like a champ. Most people notice the difference within the first range session or two.
Keep a spare or two of these on hand if you run a Kimber compact carry gun. Factory magazines paired with your pistol make all the difference in real-world reliability.

Frequently Asked Questions
Will this compact magazine work with my specific Kimber 1911 model?
This magazine is engineered for Kimber Compact and Ultra frame sizes and also works with Colt Officer's Models. However, it's not compatible with Kimber Ultra+ models. If you're unsure about your specific model, check your pistol's frame size or contact customer service to confirm compatibility before ordering.
The spring seems really stiff. Is something wrong with my new magazine?
Factory magazines ship with strong springs to ensure reliable feeding and round retention during storage. The stiffness is completely normal and breaks in after a few loading cycles, usually within your first range session or two. Load it a few times and the spring will loosen up to feel more comfortable.
Can I use this with other 1911 brands besides Kimber?
The baseplate is specifically engineered for Kimber Compact and Ultra frames and Colt Officer's Models for optimal fit and reliability. While some 1911s share similar dimensions, using this magazine outside those platforms isn't recommended since fit and feeding can vary significantly between manufacturers.
Is the baseplate removable for cleaning?
The baseplate is spot-welded and not removable, which is standard for factory Kimber magazines. As long as you keep it clean and dry, it will last a long time. If you need to clean the internals, contact Kimber service for guidance on factory maintenance options.
