CMC Products 15150 Power Mag Stainless Steel with Black Base Pad, Detachable 10rd .45 ACP Magazine for 1911 Government$32.35
Availability: In Stock
The CMC Products MRPM45FS10B is a 10-round magazine purpose-built for full-size 1911 Government models in .45 ACP. If you shoot a 1911, magazine reliability is everything—it's where most malfunctions live. Chip McCormick Custom engineered the Railed Power Mag (RPM) to eliminate that weak point. The dual-wall feed rails create the smoothest feeding surface in a 1911 magazine, and the stainless steel construction with laser-welded tube is designed to outlast standard mags by at least 2X. This is the magazine for shooters who run their guns hard—competitions, defensive training, or just putting serious rounds downrange.
The RPM follower is alloy-frame safe, and the 19-coil high-tensile spring delivers consistent feeding through thousands of cycles. A removable base pad makes field cleaning straightforward, and the black fluoropolymer finish resists corrosion even in rough conditions. Numbered witness holes let you count rounds at a glance, and the smooth finish ejects cleanly from the mag well on reloads. When you're relying on your 1911, you need magazines that work every single time.
Whether you're a competition shooter, defensive trainer, or just someone who respects the platform enough to run quality gear, the Railed Power Mag is purpose-engineered for real-world reliability. It's not a budget play—it's a long-term investment in a proven feeding system.

The MRPM45FS10B is designed for full-size 1911 Government models in .45 ACP. If your 1911 is a standard Government frame and chambered in .45 ACP, this magazine is compatible. Double-check your pistol's specifications if you're unsure.
The dual-wall feed rails are the key difference—they provide a smoother feeding surface than traditional single-rail designs, resulting in more reliable ammunition presentation to the chamber. Combined with the stainless steel laser-welded construction and heavy-tensile spring, CMC claims the RPM delivers at least 2X the service life of conventional mags.
Yes. The removable base pad allows you to disassemble the magazine for thorough cleaning and maintenance in the field or at the bench. This is practical for shooters who run their guns in dusty or muddy environments.
The numbered witness holes along the body let you see how many rounds are loaded at a glance—useful during training or competitions when you need a quick round count without unloading the mag.
