If you own an EDgun and need additionaol mag holders here's a easy way to add some. You can go from one to four, actually eight if you used both sides of the gun. I bought the acetal 1"x1/8" black bar and plastic 1/4-28 black bolts from McMaster Carr. Fastened to the side of the breech with 3m tape. I know most folks opt for power and probably don't need extra holders, but if you do this works really well. Drill press helps but could be done with hand tools. Just thought I'd share.
