The Champion is similar to a Colt Commander, with the Champion having a 4" barrel and full-sized grip frame. (A Commander has a 4.25" barrel) Therefore, you can use regular Government model 1911 magazines, such as the Wilson 47D.
Interesting.. I got a 47D mag for the Champ. Works great with ball ammo and "some" defense ammo. ie Ferdal HS and other stuff BUT my Federal EFMJ ammo will hand on the top slightly.. will not feed everytime.. I measured it with a caliper only measures about .008 longer then the stuff that works..
perfect for the other stuff though thanks for the info
