Pure Performance. Absolute Precision. Complete Reliability.


Check-Mates’ unwavering fixation with creating the finest magazine has lead to an unparalleled number of innovative features each one more ground breaking then the next.

Check-Mate’s 1911 .45 ACP magazines are made from the highest quality American milled stainless and high carbon steel. Every tube is through-hardened for exceptional strength and durability. Each Tube is polished inside and out to eliminate drag and our proprietary welding techniques insure solid welds that won’t break. Check-Mates high-performance springs offer high quality, outstanding reliability, and exceptional spring endurance.

Every detail from the feed lip to floor plate is driven by the same concern for excellence.

Staying true to Check-Mate’s standard of excellence, the 1911 .45 ACP magazines are produced using the finest American milled stainless and high carbon steel. The proven inherent reliability of these magazines practically speaks for itself. Check-Mate guarantees outstanding quality and maximum longevity for the .45 caliber magazine by hardening each tube and utilizing proprietary welding techniques. In addition, many of our magazines house Check-Mate’s patented follower, designed with an extended front skirt with an anti-friction self-lubricating finish and proper dimple placement for exceptional feed and function with every round.
