A new order will probably take 6-8 months to fill. Most distributors (and many authorized dealers) always have a number of orders in. So if the distributor(s) your dealer is working with put in orders 6+ months ago AND they don't allocate them to somebody else due to their large backorders he could get one next week. Or if that distributor doesn't have any on order and orders one for him it would probably be 6+ months before he sees it. It just depends. But best guess on a new order with CZ-USA is 6-8 month before it gets filled.
It's a very popular model and a lot are shipping, but there is a huge backorder.
