If your picking a PCR or one of the alloy compacts I'd say go with the decocker.
The lightweight alloy CZ PCR, and P-01 are only available for now in the U.S. as decockers. The polymer P-07, has the Omega trigger system which is switchable.
I don't see many CZ's a local gun stores. The response I get from many is, "we don't get many requests for them, but those that want them know what they want".
