I am willing to bet I've had more CZs through my hands than many people, and fit and finish was never an issue, even including the guns made in the US. I can say that the plandemc caused a LOT of hate and discontent in a lot of places and for all we know, CZ-UB lost people to the bug or quit work because of lock downs in the Czech Republic, no idea. I can say that the very few times I needed the warranty department, all was fixed lickety split.
