Chip McCormick Combat Power 1911 Full Size Handgun Magazine Black .45 ACP 10/rd M-PM-45FS10-B UPC 738435030957
Product Description
The Chip McCormick Custom (CMC) Power Mag 10-Round .45 ACP Extended Magazine (MPN: M-PM-45FS10-B) is a professional-grade single-stack magazine engineered to maximize ammunition payload, feed reliability, and structural longevity for full-size 1911 handguns. Featuring a corrosion-resistant black fluoropolymer coating over heavy-gauge laser-welded stainless steel, this extended magazine delivers an extra 2 to 3 rounds over standard flush-fit single-stack configurations, making it an exceptional choice for USPSA/IDPA competition, tactical defense staging, and high-volume range use.
Built with CMC's patented rocket-wire spring technology and a steel dual-radius follower, the Power Mag prevents nose-diving and uneven feeding of heavy 230gr FMJ or wide-mouthed hollow-point defensive ammunition. The extra-length stainless steel tube extends below the frame well and is fitted with an impact-resistant polymer base pad sleeve to protect the magazine during drop-free tactical speed reloads on hard concrete surfaces.
Precision-stamped with clear capacity witness ports and engineered for seamless magwell seating across Government and Commander length 1911 frames, the M-PM-45FS10-B magazine sets the industry benchmark for heavy-duty rimmed cartridge feeding. Backed by Chip McCormick's 100% Satisfaction Guarantee, it delivers match-winning performance and rugged combat durability.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard 1911 Government (5-inch) and Commander (4.25-inch) full-size grip frames chambered in .45 ACP. (Note: Will extend past the base of Officer/Compact size 1911 frames but will function; not compatible with 9mm, 10mm, .40 S&W 1911s, or double-stack 2011 platforms).
- Perform a complete firearm safety check: drop the installed magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- To load, press .45 ACP cartridges firmly down and rearward against the follower, ensuring each cartridge seats completely against the rear steel wall.
- Inspect the numbered side witness holes to visually verify cartridge count (up to 10 rounds).
- Insert the magazine firmly into the 1911 magwell until the frame magazine catch engages with a distinct, positive tactile click.
- Depress the magazine release button during reload drills to verify smooth, drop-free ejection under its own weight.
