Just got off the phone with a pistol smith who specializes in CZ, DW, and DWX optics cuts. He intimated that there was a power struggle between Colt and legacy DW/CZ personnel affecting product development and support. For example, he noted that the engineer behind the DWX is no longer employed by the company. He mentioned the nobody can predict product availability, and we should assume the worst - parts not in stock may never be in stock.
