I have concerns about how well hidden my CZ is when IWB carrying. I have never tried to carry OWB concealed. Well, not since my mid 20's when I was carrying a Colt Combat Commander in a Roger's Pancake Holster (hi-rise, forward cant, thumb break, black) but that was only in the winter/cold months when a coat would cover it (or so I thought, till that town cop followed me around in a Murphy's store all evening that time.)
I ran across that old holster a few weeks ago. I need to see if it fits the P07 or P09 and see how well it conceals under a shirt.
