It just depends on what you want. There are a number of fine CZ choices. First off determine if you want striker or hammer fired. If striker one of the P-10C or S models would be great. If hammer, P-07, PCR, and P-01 are all good choices. If going hammer determine if you want a rail for a light or not. There are some other choices as well, but those are some of the main ones.
I'd rule out the P-09. It's a great gun but larger than I personally would want to conceal.
