welcome,
the original non BD afaik had wood grips and i think later on they changed.
if you want the BD version, you are best to wait for one.
you dont say where you are from, but there are gun auction/selling sites if you haven't looked at those. Even with the panic buying going on, chances are not many people are snapping up CZ97s.
also, fwiw, the last time i bought a gun, there wasnt a shelf life or "best used by" date stamped on it.
If you want, you can ask the shop owner if its new, used or whatever and how long they had it. chances are they will know how long its been on the shelf if that really maters to you.
also as far a grips/sights go, its not like they are part of the frame/upper. They are like rims on a car/truck. If you dont like them, change them.
