Description
If you own a 1911 with an aluminum alloy frame, you want a magazine engineered specifically for that platform. The CMC Power Mag Plus delivers that performance without any compromises. The defining feature here is the POWER+ follower design that stays contained within the magazine tube itself, which means it won't contact the frame when you drop the slide on an empty mag. That's a real advantage over traditional designs, especially on lighter-frame Government or Commander models.
Power Mag Plus Spring System and Materials
The engineering starts with the spring. CMC built more coils of high-tensile rocket wire into this magazine while keeping the overall profile lean and sleek. The laser-welded stainless steel body resists corrosion and takes a beating without cracking or spreading feed lips. This tube construction is something CMC takes seriously, and it shows through years of reliable use across different 1911s and shooting environments.
Design Engineered for Long-Term Service
The all-steel follower won't wear down or degrade from heat like plastic alternatives. The removable base pad makes field cleaning quick and straightforward, while numbered witness holes let you count rounds at a glance. CMC manufactures these magazines on dedicated tooling with tolerances that run 75% tighter than military specifications, which translates to tight fitment and consistent performance across different 1911 platforms.
Built Right in America
This is an American-made magazine manufactured completely in-house by CMC on their own tooling. Since 1986, the Power Mag series has built a reputation for reliability and service life that speaks for itself.

Frequently Asked Questions
Is the Power Mag Plus really safe for aluminum frame 1911s?
Yes, the POWER+ follower in this magazine is specifically designed to stay within the confines of the tube and won't contact the frame when the slide is released forward with an empty magazine. That's the whole point of the Plus design. If you own an aluminum alloy frame 1911, this magazine was engineered with your gun in mind.
How does the spring compare to standard 1911 magazines?
CMC uses aerospace-grade rocket wire with more coils than standard designs, giving you a stronger spring that handles full-capacity loading without fatigue. The added spring power improves both reliability and service life, especially over extended periods of storage or heavy use.
Can I use this magazine with steel frame 1911s?
Absolutely. The Power Mag Plus works with any full-size 1911 Government or Commander, whether the frame is steel or aluminum. The follower design is simply more specialized to protect aluminum frames, but you get the same quality engineering and reliability regardless of your frame material.
What makes the removable base pad useful?
The removable polymer base pad lets you quickly disassemble the magazine for thorough cleaning and maintenance in the field. You can also replace it with different base pads if you need to customize the magazine for different carry or competition setups.
