Check-Mate 1911 Magazine – 40S&W Match – Dependable

Check‑Mate 1911 Magazine – Stainless Steel – 40S&W

When performance matters most, Check‑Mate 1911 Magazine delivers. From the very beginning, Check‑Mate has focused relentlessly on building the finest 1911 magazines available. As a result, every design incorporates innovative features that continually raise the standard for reliability, durability, and feeding consistency.

Premium Stainless Steel Construction

Strength, Durability, and Smooth Operation

To start, Check‑Mate forms each magazine tube from the highest‑quality American‑milled stainless steel. Then, the tube is through‑hardened to ensure exceptional strength and long service life. Moreover, both the interior and exterior surfaces are polished to eliminate drag. Consequently, cartridges move smoothly, feeding remains consistent, and wear is reduced over time.

Advanced Follower Design

Controlled Feeding with Every Round

Equally important, the patented Check‑Mate follower features an extended front skirt with an anti‑friction, self‑lubricating finish. Because of this design, the follower stays stable throughout the entire cycle. In addition, proper dimple placement ensures controlled cartridge release, which enhances feeding reliability with every round in the magazine.

High‑Performance Spring System

Consistent Tension, Long‑Term Reliability

At the same time, Check‑Mate equips each magazine with a proprietary high‑performance spring. Therefore, spring tension remains consistent shot after shot. Furthermore, exceptional spring endurance ensures reliable feeding even after extended use, whether at the range, in competition, or on duty.

Optimized Feed Lip Geometry

Reliable Feeding Across Ammo Types

Additionally, Check‑Mate’s unique wadcutter feed lip geometry maintains a consistent cartridge angle. As a result, the magazine feeds a wide range of ammunition with outstanding reliability. This attention to geometry helps prevent nose dives and feeding disruptions under demanding conditions.

Built with Purpose, Down to the Details

Excellence from Feed Lips to Floor Plate

Ultimately, every detail, from the feed lips to the removable floor plate, reflects Check‑Mate’s commitment to excellence. Because of this dedication, Thunder Mountain Custom proudly partners with Check‑Mate Industries to offer what many consider the best 1911 magazines available today.

Trusted by Professionals and Competitors

Proven in Defense, Duty, and Competition

Finally, Check‑Mate has earned its reputation as the number‑one magazine manufacturer for defensive use, law enforcement, and competitive shooting. Once you run one, the difference becomes clear.
