The Pro has a full size grip on it so the Mec-Gar ones would work....... there is one(Polymer Pro) at my LGS I was just looking at yesterdayWe were looking for the same mags awhile back; Kimber did not have any in-stock, and there does not seem to be any aftermarket mags available. Mec-Gar lists a 14-rounder for the full-size, but nothing for the Pro.
