No experience with their shotguns, did see Tom Knapp do an exhibition a last spring outside of Pittsburg, Kansas shooting the new CZ shotgun. He was also shooting thrown aspirins with a CZ .22 Mag as well though.
My wife and I have got a pair of CZ 452 .22 rifles, couldn't ask for a better bolt action .22. Brother in law just picked up one for my niece and nephew. Know several that have had .22 Hornet and .223 bolt guns from CZ with good reviews.
Their double shotguns are made for them in Turkey. Somebody mentioned above here that they thought the autoloaders were as well, that I don't know, quite possible.
