My RO runs just fine with springfield factory mags and loves the one Wilson Combat 8 rounder that I have (need to look into getting some more of those.) Picked up some old colt "surplus" magazines for cheap and it didn't like those at all.
Do the surplus mags say Colt on them?
Tripp Research Cobra Mags are the best out there IMO. I run the hell out of them in my 1911's that I shoot USPSA matches with.
