Description
The CMC Power Mag Plus represents refined 1911 magazine engineering designed specifically for shooters running aluminum alloy framed pistols. Where standard magazines can push a follower forward and contact the frame when the slide drops on an empty gun, the unique POWER+ follower remains contained within the tube, keeping your lightweight receiver safe from damage.
What Sets the Power Mag Plus Apart
This magazine combines CMC's decades of competition-proven design with practical safety improvements. The steel follower isn't just durable—it also functions as a spring itself, which means the rocket wire coils can be larger and more powerful than typical designs. You get superior spring strength packed into a standard-length package. The all-steel follower resists wear, handles heat, and won't degrade over time like polymer alternatives. Numbered witness holes on the side let you count your rounds at a glance, and the laser-welded tube creates a smooth seam with no sharp edges.
Built for Real Conditions
Stainless steel construction handles dust, moisture, and neglect far better than blued steel. The smooth finish makes loading and unloading effortless, and the removable base pad comes apart in seconds for quick cleaning. Whether you're running it through a competition, keeping it as a backup, or carrying it loaded, the tight tolerances—held 75% tighter than military spec—keep feeding consistent. The design works particularly well if your 1911 has seen some use or isn't perfectly tuned, which makes it reliable across a range of different guns.
Proven Track Record
CMC has built a reputation spanning nearly 40 years by solving the one thing that matters most: magazines don't fail when it counts. The Power Mag Plus carries that heritage forward with a gun that won't let you down, whether you're training, competing, or trusting your life to it.

Frequently Asked Questions
Why would I choose the Power Mag Plus over a regular Power Mag?
The POWER+ follower on the Plus version stays contained within the magazine tube, which means it won't contact your pistol's frame when the slide drops on an empty magazine. This is especially important if you own a 1911 with an aluminum alloy receiver. The regular Power Mag follower can extend slightly forward under certain conditions, potentially marking a softer frame material. The Plus gives you complete peace of mind with aluminum frame guns.
Will this magazine work in my 1911 if I'm not sure about my frame material?
If you have a steel frame, either magazine works fine. But if you're running an aluminum or alloy frame—common on many modern production 1911s—the Power Mag Plus is the correct choice. When in doubt, the Plus is the safer bet. It's the same quality magazine with a smarter follower design for the guns that need it.
How many coils does the spring have compared to other magazines?
CMC's rocket wire spring in the Power Mag Plus has more coils than their fixed base Match Grade and Classic magazines, which allows for greater spring tension in the same space. The steel follower also doubles as a spring element, so you get additional strength from the follower itself. This dual-spring design is why the magazine maintains consistent feed pressure even after hundreds or thousands of load cycles.
Is the base pad removable, and why would I want to remove it?
Yes, the polymer base pad slides off easily for cleaning and maintenance. Removing it lets you flush out any dirt or debris from inside the magazine tube and access the spring and follower if needed. It takes about 30 seconds and makes keeping your magazines in top shape much simpler, especially if you run them hard or in dusty environments.
