For shooters who demand rock-solid feeding and durable construction from a 1911 magazine, the right choice can make a measurable difference at the range and in the field. Small design choices—rail geometry, spring type, and tube construction—drive reliability with hard-to-feed cartridges like .45 ACP.
CHIP MCCORMICK CUSTOM 1911 RPM is an RPM Railed Power Mag designed to fit a 1911 Colt and hold up to 10 rounds of 45 ACP. The magazine features dual wall feed rails, a laser welded stainless tube, and 19 coils of rocket wire spring—components selected to improve feed consistency and longevity. Shop this product

Design and construction details
The dual wall feed rails on this magazine provide a rigid, low-friction interface with the 1911’s frame, helping maintain consistent alignment during rapid firing or when operating under stress. The laser welded stainless tube resists corrosion and maintains straightness under repeated use—critical for a magazine that will see regular loading and unloading. The 19-coil rocket wire spring is engineered to provide even pressure throughout the stack, reducing follower tilt and improving top-round presentation for .45 ACP cartridges.
Why 10-round .45 ACP capacity matters
A 10-round capacity for .45 ACP balances firepower with concealability and compliance in many jurisdictions. The .45 ACP cartridge offers proven stopping power and manageable recoil in a properly tuned 1911 platform. This magazine’s internal geometry and spring choice are optimized for the wider .45 ACP case, minimizing common feed issues associated with single-stack designs.
Practical use and maintenance
Field maintenance is straightforward: periodic cleaning of the stainless tube and light lubrication of the rails keeps function smooth; replacing the rocket wire spring only after heavy use preserves performance. Because the magazine is purpose-built for Colt-style 1911s, expect drop-in fitment and reliable cycling when paired with a properly maintained pistol. View product details and pricing
