I'm in the same boat.... no 10 rd mags in the USA???, Why???. Canadian & UK sites say they are in stock? but no shipping to the USA... Gun is near useless for competition with one 5 rd. mag. And another thing.... I didn't see a phone # for CZUSA? No way to contact them other than email (did it)... No response yet.
Thousands of the things are being shipped, but it's just part of the general firearms market at the moment. Demand FAR exceeds ability to produce. I'm pretty sure the CZ-USA webstore has a notify me when in stock feature. I'd suggest sighing up for that, but keep looking online at other sources as well. The way things have been it's going to be a long time before some gun stuff (guns, mags, ammo, etc.) is easily available. Good luck in your search!
