From my experience- CZs remain the same quality wise. Think you’ve selected some good options to choose from.
Of the three choices, I prefer the P01- mine is an omega, but I also have a PCR. I also have a P10c & P09. I’ve shot them all in my IDPA games and all served me well. My feedback is below, but think you need to ask 2 Qs- do you want a hammer gun or striker? Do you want metal frame or polymer? These are preferences & only you can choose. If you were local I’d offer you the chance to shoot them & see what works best for you.
To me, the P01/PCR size is the best balance of ergos, accuracy, capacity and carry ease. Every time I shoot another gun for a while and retry my CZs, I go back to them. They just work best for me. Aftermarket grip panels are available to help adjust the grip , especially with those with palm swells. I prefer hammer guns the more I use both hammer and striker.
The P09, while larger then the P07 has similar ergos. It’s superbly accurate and reliable. Like my P01 Omega it can swap from decocker to manual safety. That said, the P01/PCR has better ergos for me. YMMV. As with the P10 you can adjust the grip w/ replacement back straps- to me not as good as the grip panels with metal framed guns.
My P10c is a very, very good striker gun, and it’s one of my favorites but in the end I prefer hammer guns. I’ve had/ have SiG P320s, M&P, XD, Glock, PPQ. It fits me well. The P10’s advantage IMO is cost. Mine is also accurate and reliable.
Good luck in your search. You can’t go wrong with either IMO. Let us know what you decide.
