I have a custom Dan Wesson which I'm having issues with the first round going into battery with a loaded magazine which is 7 rounds. If I load 6 rounds or less it chambers fine. I tried it with factory ammo and my reloads I also purchased a WC magazine with the same results. I noticed some copper markings just before the barrels feeding ramp which is about 1/32" away from frame. Dan Wesson is sending me new magazines because I was pretty confident it was a magazines issue but I'm not so sure now. Any input would be appreciated.
