Jim,
I understand it will show up online. I've seen it myself. That was my point regarding bad news always travels far and wide on the internet. Just because it shows up doesn't necessarily mean it's a common problem. Sorry that Winchester doesn't support it's customers like CZ-USA does, but if you never tried, you really can't blame CZ. If I had to send a firearm to CZ it would travel close to the same distance. Surely there is a process in your country for returning a firearm to the distributor for repair. From what I hear our Canadian neighbors have less than satisfactory importer support also.
Let's face it, it's a mass produced firearm built to a price, and any time that scenario occurs, occaisionally, bad examples leave the factory. I have more than one CZ, and all were bought used. Other than a 452 FS in 22lr that ejects inconsistently, I have no issues with any of them and consider the brand a good value.
I hope you get your issue resolved.
