I agree that the PCR is really one of the best alloy framed decocker CCW pistols every made. The P-01 is outstanding, but if you don't need an M-3 rail, and like pow mount sights, the PCR is a better choice.
The P-07 is an excellent pistol, and the new improvements make even closer to being the P-09's little brother, however, if you elect to carry the P-07 concealed, I would heartily recommend an undergarment between you and that sandpaper grip. It's designed to stay in your hand while firing in a blizzard after being soaked in oil, but that same grip can chew up the skin on the side. Ask me how I know.
The P-09 is fantastic, but a wee bit bit unless you get a good holster/belt combo to carry it concealed. I recommend High Noon Holsters,
http://www.highnoonholsters.com/ for great CZ holsters for all CZ pistols. Below is the P-07 in a Slide Guard,
And my current carry pistol, my CZ SP-01 Phantom in a High Noon Down Under IWB rig,
Big guns can be carried concealed, if you work at it,
Also remember that if you DO want a rail, they can be useful, like a CZ P-09 with NEBO light for a home defense set up.
Whatever you choose, I hope this helped, and please post pictures when you get your new CZ!
