SGM Tactical 26 Round Magazine For Glock 21

The SGM Tactical 26‑Round Magazine for Glock 21 is a high‑capacity .45 ACP magazine built for shooters who want more rounds on tap with fewer reloads. Designed to be compatible with Glock 21, 21SF, 30, 30S, and 41 pistols—as well as many Glock‑pattern .45 ACP pistol‑caliber carbines—this magazine is well‑suited for range days, home‑defense setups, and PCC builds that benefit from extended capacity. Its 26‑round capacity offers a significant step up from standard factory magazines, giving you more trigger time between reloads and more flexibility in drills or defensive scenarios.

A tough, glass‑filled polymer body with a full‑length, heat‑treated stainless steel liner provides strength and rigidity while resisting flexing or bulging when fully loaded. The internal stainless steel spring and polymer anti‑tilt follower are engineered to support reliable feeding, even when the magazine is loaded to full 26‑round capacity. Many users note that the strong spring benefits from a mag loader, which helps make filling all 26 rounds easier and preserves spring tension over time.
