While I don't have a RIA I do have a 10mm 1911.
I have factory Colt, Mec Gar and Metalform magazines for my Delta and all work great.
I tried some Wilson Mags as I have a bunch for my 45's. They sucked, I had problems with the last round, failure to feed and the follower. Wilson wasn't real interested in solving my problems either. That surprised me because in the past they were always helpful.
