Kimber factory mags are CMc and my source was Kimber, NY themselves when I called them "complaining" about the mag that came with my Pro CDP. I told that since I was paying quite a bit for the pistol that why cannot it come with at least a Chip McCormick since they use his parts. Their answer, "Well that one that came with the pistol sir, is a Chip McCormick mag and the same with all the other pistols shipped out to dealers."
