There was gentleman named Cooper that was rather taken with them, his only regret was that they were invented in a communist country and that it was 9mm. He called it the "Brunner pistol".
While I don't currently own one, I've shot them, had them as range guns and worked with folks who were issued them. I also shared beer with a CZ rep in Germany (short story).
They are dependable and accurate. I happen to like The frame mounted safety or decocker (based on variant). They were also making affordable competition semi-autos, but I believe Canik might have displaced them from the most affordable position.
CZ has been making some significant acquisitions as of late, Dan Wesson, Colt, S&B, etc. They are a quiet powerhouse. Their parent company is also a european defense contractor.
