CZ's first foray into the polymer market. Son In law bought one and we tried to fire it today. Double action shooting IE first shot worked, but after that the problems began. In single action the trigger is not disengaging the sear. You can make it go off if you shake it and squeeze like a mad man. The trigger bow is not pushing the camming piece up high enough to disengage the sear. I'm sadly disappointed in this as CZ has better reputation for quality than this. It will have to go back to the factory. Anyone else have any experience like this with a CZ PO7?
