my estimate for availability - late summer 2022.
why do I say that?
When I was still a Pro-Staff demo rep for the company that used to handle CZ in the upper Midwest, I put in a pre-order for a full-sized DWX in .40 at a significant discount from MSRP. Set aside the cash to pay for it.
After the world ended in 2020, CZ stopped having demos and changed the relation with the companies which represented them. I am no longer Pro-Staff, so I don't expect to see the pre-order honored by CZ/DW.
Instead I commissioned a blade from a Master Bladesmith. I will be spending most of the price of the DWX on this. Based on the smith's lead time, I expect my blade to be finished July/August of next year. Once I spend the reserved $$$ for it, the DWX will then become available.
