2011 Magazine 126mm Stainless Steel – 15 RD – 40S&W / 10MM

2011® Compatible 15‑Round 140mm Stainless Steel Magazine – 40S&W / 10MM

Eliminate common feeding issues on your 2011 platform with the Check‑Mate 2011® Compatible 15‑Round Stainless Steel Magazine. From the very first round to the last, this magazine focuses on smooth operation, consistent feeding, and long‑term durability. As a result, shooters gain confidence, reliability, and repeatable performance under all conditions.

Designed for Top‑Tier Performance

First and foremost, this magazine fits Staccato 2011® and other 2011 platforms precisely. Because of this exact compatibility, it seats securely and feeds reliably without unnecessary tuning. Moreover, Check‑Mate manufactures each tube from premium American‑milled stainless steel and then fully through‑hardens it. Consequently, the magazine resists deformation, feed‑lip spread, and long‑term wear even under heavy use.

Additionally, Check‑Mate polishes both the interior and exterior of the magazine tube. Therefore, friction is significantly reduced, cartridge drag is minimized, and feeding remains smooth during rapid strings and high‑round‑count sessions.

High‑Quality Components Working Together

Equally important, the follower uses Check‑Mate’s anti‑friction, self‑lubricating polymer design. Because of this material choice, the follower moves freely and consistently throughout the magazine body. At the same time, the high‑performance magazine spring delivers strong, even pressure from the first round to the twentieth. As a result, feeding remains reliable and predictable over thousands of cycles.

Together, the precision tube, advanced follower, and endurance‑rated spring form a balanced system that maximizes reliability while minimizing maintenance concerns.

Built for Strength, Endurance, and Reliability

Furthermore, the through‑hardened stainless steel construction provides long‑term resistance to wear and deformation. Since the polished tubing prevents rounds from sticking or binding, the magazine continues to function smoothly even in demanding conditions. Consequently, competitive shooters, duty users, and recreational shooters all benefit from professional‑grade performance and peace of mind.
