I bought an Urban Gray P01 with the rubber grips. I liked them. I carried it IWB, t-shirt next to me and a button up shirt, untucked, on the outside.
I liked the way those grips felt so much that I bought a pair for the older satin nickel CZ75 Compact my wife was using. Then I bought a set for the Pre B CZ85. I think I ordered another set for another CZ75 Compact later. Now all the metal framed CZ's (except the Tactical Sport) have the rubber grips.
We've carried four of them concealed. Never noticed a shirt thing.
