CZ is rolling them out as fast as they can, but the major difference with CZ and American manufacturers is that CZ has a world wide market, plus major military contracts to fill with P-07s, Phantoms and BREN/EVO rifles/carbines. Production is fit in as best as possible, and what they can send goes on the plane - no more boats, too slow.
Hopefully the next plane that touches down is filled with P-09 boxes, and back orders will be filled, but it's really a guessing game on what the factory is going to send.
