Reliable magazines are the foundation of a defensive 1911 platform. Consistent feed geometry, durable construction, and a spring that resists set are what separate a field-ready spare from a liability at the range or in a high-stress situation.
CHIP MCCORMICK CUSTOM 1911 RPM is a 10-round railed power mag designed for 1911 Colts, built to deliver repeatable function and long service life.

Design and fit
Built by Chip Mccormick Custom with attention to 1911 tolerances, this magazine features dual wall feed rails that stabilize the follower and round during presentation. The laser welded stainless tube resists corrosion and keeps body dimensions true under repeated use. It is offered in various models to suit sight and slide clearances and will accept up to 10 rounds of .45 ACP—ideal for duty, competition, and defensive carry in full-size 1911 Colt frames.

Performance characteristics
Spring and feed geometry
The magazine uses 19 coils of rocket wire spring engineered for even pressure across the stack. That many coils translates to a controlled feed rate, reduced follower tilt risk, and a longer spring life compared with fewer-turn designs. Paired with the dual wall feed rails, the result is a smooth, predictable feed cycle for .45 ACP rounds.
Materials and longevity
Laser welded stainless construction minimizes deformation and provides corrosion resistance—important for defensive gear kept in holsters, pouches, or climates with humidity. At a price point of $37.79, the magazine represents a cost-effective upgrade for shooters who want aftermarket reliability without breaking the budget.

Care and recommended use
Inspect the magazine body for dents, keep the lip area clear of burrs, and rotate springs periodically if stored loaded. For defensive use, pair with quality ammunition and cycle the magazine at the range to validate function under your gun’s specific feed geometry.
