If you have big enough pockets, the CM9 is a very attractive little pistol... I think it would make a great IWB firearm as well and would trade my CW9 for one if I had the chance.
For me, the CM9 is still too big for pocket carry and the CW380 is perfect for me in that regard... I also have a Blackhawk ankle-holster for the 380 because I find the calf-strap to be required for proper ankle carry.
