Description
This Iver Johnson drum magazine brings serious capacity to your 1911 without unnecessary bulk. Purpose-built for the Iver Johnson 1911A1 Carbine, it feeds reliably in any standard Government full-size 1911 platform. Whether you're an XL 6-inch, Government, Commander, or Officer model shooter, this magazine will lock in securely and cycle smoothly when properly maintained.
The construction combines a steel magazine with a polymer drum housing and polymer floor plate, giving you a balanced design that won't bog you down at the range. The black finish keeps things sleek, and witness holes on both sides let you know exactly how much ammunition you have left. At 10.1 inches in length, it's compact enough that you won't have mobility issues, though expect it to feel substantial when fully loaded with 28 rounds of .45 ACP.
Drum magazines are built for fun and high-volume shooting sessions. No lubrication required, which keeps things simple. The lever-activated loading system makes filling it easier on your hands compared to traditional stick magazines. This is the kind of mag you bring to the range when you want to spend more time shooting and less time swapping magazines. Keep your main carry mags as your reliable workhorses and let this drum handle the recreational fire.

Frequently Asked Questions
Will this drum magazine fit my 1911?
This drum is designed for full-size 1911 Government models and will work with Iver Johnson, Colt, Springfield, S&W, and other standard Government profile 1911 pistols in .45 ACP. It fits XL 6-inch, Government, Commander, and Officer models. If your 1911 uses a double-stack or proprietary magazine, verify compatibility before ordering.
Do I need to lubricate this magazine?
No. The Iver Johnson 1911 drum is designed to operate without lubrication, which keeps maintenance simple. Just keep it clean and it will work reliably.
How do I load this drum magazine?
The magazine features a lever-activated loading system on the side that makes loading easier on your hands. Move the lever, drop in a round, and repeat. This is much gentler on your thumbs compared to standard stick magazines, especially when you're loading all 28 rounds.
Are drum magazines reliable for actual shooting?
Drum magazines are best viewed as range accessories for high-volume shooting fun rather than primary carry or duty mags. Build quality varies by brand and individual examples. Proper maintenance and avoiding over-compression during storage will help maintain function.
How heavy is this magazine when loaded?
Fully loaded with 28 rounds of .45 ACP ammunition, this drum magazine becomes noticeably heavy. It's comfortable to shoot with but definitely a range toy rather than something you'd want on your hip for extended periods.
What are the witness holes for?
The witness holes on both sides of the magazine let you quickly see how many rounds remain without removing the magazine from your 1911. This is handy at the range so you know when to reload.
