CZ-UB does have a nifty little 22 pistol the CZ 122, but it is unimportable to the United States due t the Nazi inspired Gun Control Act of 1968. Perhaps it can be built here someday, or we might get some inspired leaders to overturn GCA of '68, but I seriously doubt the latter.
I would love to have one. The Kadet Kit I can tell you from personal experiance is a LOT of fun - grab one.
Edit to add I can't find the 122 Sport pistol on the CZ-UB webpage anymore. It may be out of production. Too bad, it was one racy looking pistol, and would have been neat to make in the Dan Wesson plant.
