Mag Auto Ord 50rd Drum 45acp Bl

The Auto Ordnance 50-Round Drum Magazine for .45 ACP is a legendary high-capacity feeding solution designed specifically for Thompson submachine gun platforms. Built from steel construction, this drum magazine holds fifty rounds of .45 ACP ammunition, delivering extended fire capability without the need for frequent reloads during training, competition, or tactical exercises. The 50-round drum represents the original high-capacity standard for Thompson firearms and remains a sought-after accessory for collectors and operators working with vintage or modern Thompson-pattern firearms.

The steel construction ensures durability and maintains structural integrity under repeated loading cycles. Drum magazines function differently than stick magazines—the spring tension must be properly wound and maintained to ensure reliable feeding through the entire fifty-round capacity. The .45 ACP cartridge, with its larger diameter and heavier projectile compared to 9mm, benefits from the drum's geometry and feed path engineering, which was purpose-built during the Thompson's original military development. Dimensions of 7 x 3 x 11 inches accommodate the drum's distinctive circular profile, and the 2.69-pound loaded weight reflects the substantial ammunition capacity.

This Auto Ordnance drum magazine is intended for Thompson owners seeking authentic, period-correct magazines or those who want extended capacity for range sessions and transition drills. The 50-round configuration is particularly valued in historical reenactment, civilian sport shooting, and dedicated Thompson platform shooters who appreciate the challenge and novelty of managing a traditional drum-fed platform. Proper care and inspection of the internal spring mechanism before use ensures consistent performance across the full fifty-round count.

The Thompson submachine gun remains an iconic platform in American firearms history, and original-specification magazines like this 50-round drum are essential components for operators maintaining authentic configurations. The .45 ACP cartridge's subsonic velocity characteristics and manageable recoil made it ideal for the Thompson's open-bolt design, and the drum magazine's capacity enhanced the platform's role in close-quarters scenarios. Today, the Auto Ordnance drum magazine bridges collector interest with practical shooting applications.
