Chip McCormick Power Mags combine a streamlined profile with heavy-duty construction designed for enhanced reliability and extended service life. The all-steel follower design minimizes bearing surface contact, enabling consistent function in harsh conditions where regular maintenance may be limited. This follower design also serves as a spring mechanism, allowing the high tensile rocket wire spring coils to achieve the largest dimensions—side to side, front to back, and top to bottom—of any extra capacity .45 caliber 1911 magazine.
The Power Mag 45 ACP holds an 8-round capacity and is purpose-built for the 1911 Officer platform.
