It looks like a great gun. I had a CZ999 awhile back and really liked it but the grip was a little big for me, my wife couldn't handle it at all. They've dried up around here. The only shop that had them says they can't get anymore in. I hope the distributor of the Arex does a better job of getting them out there, and getting parts in. I'm sure they will. From the reviews, it sounds like they want to make a splash in the US market.
Congrats on finding a great pistol.
