CheckMate Match Extended SS Full Size 1911 Magazine 8 Round

CheckMate Match Extended Stainless Steel Full‑Size 1911 Magazine – 8 Round

Upgrade your full-size 1911 with the CheckMate Match Extended 8‑Round Magazine, which combines reliability, durability, and match-grade performance. Because it’s built for serious shooters, this magazine ensures smooth feeding, consistent lockup, and long-term performance in competition, range, or defensive applications. Moreover, it works seamlessly with full-size 1911 pistols to deliver consistent results every time.

Precision Stainless Steel Construction

To begin with, Check‑Mate forms the magazine body from high-quality American-milled stainless steel. Then, the tubes undergo through-hardening, which strengthens the steel and resists deformation. Afterward, technicians polish the interior and exterior. Consequently, friction decreases and cartridges feed smoothly, even during rapid strings of fire. As a result, shooters can rely on consistent performance under any conditions.

Extended Capacity for Full-Size 1911

Additionally, the extended design provides 8-round capacity without sacrificing spring tension or feeding reliability. Therefore, you gain more rounds while maintaining consistent cartridge alignment. At the same time, the extended profile ensures proper seating and secure lockup in your full-size 1911 pistol. This combination of capacity and precision supports both competitive and defensive shooting scenarios.

Patented Follower and High-Performance Spring

Equally important, the magazine features Check‑Mate’s patented follower with an extended front skirt. This design prevents tilting and ensures cartridges remain properly aligned. Furthermore, the anti-friction, self-lubricating finish and precise dimple placement improve last-round lockback reliability. Meanwhile, the high-performance spring delivers uniform pressure across all eight rounds. Consequently, feeding remains smooth, consistent, and dependable shot after shot.

Match-Tuned Feed Lips

Moreover, Check‑Mate engineered the feed lips to maintain the correct cartridge angle throughout the cycle. Therefore, each round feeds reliably, from the first to the last. Whether you shoot ball, hollow point, or match ammunition, the magazine maintains flawless performance. As a result, it minimizes jams and maximizes confidence in critical moments.

Built for Durability and Reliability

From feed lips to base plate, every component reflects Check‑Mate’s commitment to quality. Additionally, the stainless steel construction resists wear and maintains alignment, ensuring the magazine performs reliably for years. Thunder Mountain Custom proudly partners with Check‑Mate, offering shooters a product trusted by competitive shooters, professionals, and enthusiasts alike.
