Ok, I ordered a CBOB 10mm from Buds, and I'm really bothered by the overrun checkering issue.

I have seen some pictures with the overrun, and some without. I contacted Buds and CZ-USA (both by phone). The guy at Buds says that he thought all of them were that way, and the lady at CZ-USA is claiming this is how they were meant to be made. Can this be true?

I was really hoping to get one without this overrun, but if CZ-USA is claiming this is how it was meant to be, can you really do anything about it?
