Description
The CMC Power Mag is engineered for shooters who demand reliability without compromise. It's a 10-round magazine built specifically for full-size .38 Super 1911 pistols and made from 410 stainless steel with a laser-welded tube for corrosion resistance that holds up in less-than-ideal conditions. The construction means this magazine won't let moisture, debris, or extended storage periods slow you down.
Power Mag Follower Design
The standout feature here is the all-steel follower that doubles as the magazine spring. This design keeps the bearing surface as minimal as possible, which translates to smooth function when you haven't cleaned your gear in a while. The follower also allows the rocket wire spring coils to be larger than standard magazine springs, giving you stronger spring tension that maintains reliable feeding through years of use. You'll notice factory-drilled witness holes down the side so you can count rounds at a glance during reloads or storage checks.
Easy Maintenance and Practical Use
The removable polymer base pad comes factory-installed and can be quickly stripped off for cleaning and maintenance between range sessions or carry. This polymer pad also gives you better grip during tactical reloads without adding unnecessary bulk. The smooth stainless finish makes inserting and removing the magazine from your 1911 straightforward, with no sharp edges or catches. CMC backs these magazines with a satisfaction guarantee, and the track record shows they're built to last through thousands of rounds and years of regular use.
Made for Serious Use
Whether you're running competition, training hard at the range, or carrying a .38 Super for serious purposes, the Power Mag has earned its reputation among people who depend on their firearms. The extra capacity gives you two more rounds compared to standard 1911 magazines, and the engineering means every one of those rounds feeds reliably when it matters.

Frequently Asked Questions
Will this Power Mag work with standard .38 Super ammunition?
Yes. The Power Mag is designed for standard .38 Super Auto cartridges used in full-size 1911 Government models. The laser-welded stainless steel body and rocket wire spring are tuned to feed full-power loads reliably through normal and extended use.
Can I use this .38 Super magazine in a Commander or Officer-sized 1911?
No. This is a full-size Government magazine. Full-size magazines fit Government and Commander frame dimensions, but they will not work in Officer-sized (compact) 1911 pistols, which require shorter compact magazines.
What makes the all-steel follower different from plastic followers?
CMC's all-steel follower design has a minimal bearing surface that functions with the stainless steel tube, allowing the rocket wire spring coils to be larger and stronger than standard magazines. This means better spring tension, more reliable feeding, and function in dirty conditions where polymer followers might wear or bind.
Is the base pad really removable for cleaning?
Yes. The removable polymer base pad slides off for quick disassembly and internal cleaning. This makes it easy to inspect the follower, spring, and tube between shooting sessions without any special tools.
