CheckMate Extended Blued Full Size 1911 Magazine 8 Round

CheckMate Match Extended Blued Full‑Size 1911 Magazine – 8 Round

CheckMate for Pure Performance. Proven Reliability.

CheckMate Industries builds this extended 8‑round blued 1911 magazine for shooters who demand dependable feeding and long‑term durability. From the very beginning, every design choice focuses on consistency and control. As a result, this magazine performs reliably for competition, training, and defensive use.

Precision Blued Steel Construction

To start, Check‑Mate forms each magazine body from high‑quality American‑made steel. Next, the company applies a durable blued finish that enhances corrosion resistance while maintaining a classic appearance. Afterward, technicians polish the interior surfaces. Consequently, friction is reduced and cartridges feed smoothly under recoil.

Extended Capacity with Match‑Grade Fit

Unlike standard flush‑fit magazines, this extended design provides a full 8‑round capacity without sacrificing reliability. At the same time, the added length improves spring geometry and follower stability. Therefore, feeding remains consistent from the first round to the last.

Patented Follower for Controlled Feeding

Equally important, the patented Check‑Mate follower features an extended front skirt that prevents tipping. In addition, the follower includes an anti‑friction, self‑lubricating finish and proper dimple placement. Because of this design, rounds present at the correct angle and the slide locks back reliably after the final shot.

High‑Performance Spring System

Meanwhile, Check‑Mate pairs the follower with a proprietary high‑performance spring. This spring maintains consistent upward pressure and excellent endurance over thousands of cycles. As a result, the magazine delivers dependable feeding even during rapid fire or extended range sessions.

Built for Serious Use

From the feed lips to the extended base, every component serves a clear purpose. Nothing is accidental. Every detail supports reliable function and long service life. Consequently, this magazine stands up to hard use in competition, training, and defensive environments.

Thunder Mountain Custom proudly offers Check‑Mate magazines because they continue to set the standard for quality and performance. Ultimately, this extended blued 8‑round magazine proves why Check‑Mate remains a trusted name among serious 1911 shooters.
