Description
If you run a 1911 in .45 ACP, the quality of your magazines matters more than most people realize. This Ed Brown 847 magazine is purpose-built by a company with over 50 years of custom 1911 experience, and it shows in every detail.
Built with Intent
The tube is machined from certified 410 stainless steel and heat-treated to 35 Rc for real strength and corrosion resistance. Inside, the tube is highly polished to ensure smooth operation and reduce drag on the follower and feed lips. Ed Brown uses a steel follower paired with one of the stiffest springs in the industry. That combination matters because when you run through an empty mag, you need rock-solid slide lock every time. The heavy-duty spring maintains pressure across the entire magazine life, so feeding stays consistent whether you load to capacity or carry with a round down.
Your Choice, Built In
One thing that makes this magazine different is the included base pad system. You get both a thin and thick base pad with all the necessary screws. Remove both pads and the magazine sits flush with your frame, reducing printing for carry guns. Swap in the slim pad for a low-profile look, or use the extended pad if you run a magwell. The versatility is built in without extra cost.
Feeding You Can Trust
These magazines have earned respect across the 1911 community for working reliably with every type of ammunition you want to send downrange. Factory ball ammo, jacketed hollow points, and everything in between feed without drama. Tests from independent sources like Gun Tests magazine have consistently rated Ed Brown magazines as among the top performers, with excellent fit and function that holds up under real use.

Frequently Asked Questions
Does the Ed Brown 847 magazine work with Government 1911 clones from other manufacturers?
Yes, this magazine is designed for full-size 1911 Government platforms and works with most 1911s in .45 ACP that accept standard Government magazines. That includes Springfield, Kimber, Colt, and other common 1911 platforms. Always verify compatibility with your specific pistol if you have concerns.
What makes the steel follower better than a polymer follower?
The steel follower provides direct upward pressure on the slide stop, resulting in a positive lock when the magazine runs dry. This is why Ed Brown specifically chose steel instead of the polymer followers used in some competing designs. The follower works with the heavy-duty spring to ensure the slide locks back consistently every time.
Can I use this magazine for both training and carry?
Absolutely. The included base pads let you configure the magazine for whatever role you need. Remove both pads for a flush-fit carry setup that minimizes printing, or use the extended pad at the range where a slightly larger grip doesn't matter. The same magazine adapts to your needs.
Do Ed Brown magazines come with a warranty?
Ed Brown backs these magazines with a lifetime warranty on the tube and follower. The company also offers a magazine exchange program where you can send in any old magazine with $10 to upgrade to a new Ed Brown magazine. Springs can wear over time with heavy use, and the program makes it affordable to stay equipped with fresh magazines.
