The ProMag AR-15 9mm Luger drum magazine with Glock magwell brings serious firepower to your pistol-caliber carbine platform. Built for shooters who want to maximize rounds downrange without frequent reloads, this 50-round drum is engineered specifically for AR-15s that accept Glock-pattern magazines—a natural fit for today's popular 9mm PCC builds. Whether you're running drills at the range, testing a new 9mm carbine, or building out a defensive training setup, the high capacity and reliable feed make extended shooting sessions more practical and affordable.

Construction matters in a drum magazine, and ProMag didn't cut corners here. The body is molded from durable Zytel-based polymer, chosen for its strength and longevity. Where it counts most—feeding and retention—a full-length steel insert is stamped and welded into the upper tower, mirroring the design of factory Glock magazines. The spring is heat-treated stainless steel, and the follower is injection-molded for consistent performance across hundreds of rounds.

A critical note for buyers: this drum is engineered exclusively for AR-15-pattern magazine wells and will not fit Glock pistols. If you're running a dedicated 9mm PCC platform with Glock-mag compatibility, this is your high-capacity solution. The polymer construction keeps weight down compared to steel alternatives, making it less fatiguing to handle during longer range sessions or training days.
