Keeping Traditions Alive Since 1953

The Chip McCormick Power Mag Railed magazine is purpose-built for full-size 1911 Government pistols in .45 ACP. This isn't a stripped-down magazine trying to do too much, it's a straightforward tool designed around what actually works.
The standout feature here is the dual-wall feed rail design. Instead of relying on traditional pinched feed lips that can warp and wear, these rails are laser welded and provide twice the strength of conventional magazine lips. That means no more worried glances at bent feed lips or jams from damaged edges. The railed design gives you a feeding surface that keeps running whether you're at the range for a few hours or depend on this gun for something more serious.
Internally, you get a 19-coil high-tensile rocket wire spring paired with a steel follower and removable polymer base pad. The witness holes along the side let you count rounds at a glance instead of shaking the magazine to figure out what you've got left. The magazine is laser welded throughout and finished in black fluoropolymer to resist corrosion.
This is a magazine that works best in a properly set-up 1911. Some guns may need tuning to run 10-round magazines reliably with certain ammunition types, but Chip McCormick designed these to work across the widest variety of 1911 specs possible. Whether you're practicing at the range or looking for extra capacity, these magazines deliver the dependability you expect from a brand that's been building quality 1911 magazines since 1986.
This magazine is designed for full-size Government model 1911s and compatible clones. Most modern 1911s will run these without issue, but some older or stock guns may need to be tested. Chip McCormick engineered these to work with the widest variety of 1911 specifications possible, though individual pistols can have preferences for certain magazine and ammunition combinations.
The railed design uses folded, laser-welded steel rails instead of pinched feed lips. These rails are at least twice as strong as traditional feed lips and won't warp, bend, or spread from hard use. You get a smoother feeding surface and real durability without worrying about the magazine being the weak link.
Yes, it will fit. The extra length does mean the magazine will protrude from the grip when loaded, which some shooters don't prefer for concealed carry. For range use and home defense, that's typically not an issue. Test it with your specific gun to see how it runs.
The removable polymer base pad makes cleaning and maintenance much simpler. You can take it off to access the spring and follower without disassembling anything complicated. It also makes the magazine easier to load by hand if you prefer not to use a loader.
The numbered witness holes are small openings along the side of the magazine that let you see how many rounds are loaded without opening the mag or shaking it. It's a practical feature that saves time at the range and helps you stay organized during shooting sessions.
Yes, many competitors use Chip McCormick magazines including these Power Mag Railed magazines. The reliable feeding, strong construction, and extra capacity make them solid for IPSC, IDPA, and other 1911 competitions where consistency matters.
