I use a Tommy Theiss holster for my CM9. I used to use the M-Tac, but the Theiss holster is less expensive and works just as well. I tend to like the hybrid leather w/kydex bodies. The leather backing conforms to your body and spreads the weight better. I always wear a t-shirt, so I can't answer how it feels against the skin. The kydex body is thinner then leather, and for the most part, doesn't need to be broken in. I have carried a 1911, XD45C, G36, PPS and also a G27 now using this type of holster and it's very comfortable.
