The 22 lr.s do not have a "hang-down" clip, the CZ 22 mags and 17 HMR's do though.
I am not a fan of the backwards safety but then I never put a round in the chamber of any rifle until I am ready to shoot, and if I don't fire the round then I extract it, I do not rely on a safety anyway so it really wouldn't bother me.
It is hard to say something bad about a rifle that sells in the $350 range and performs like the CZ 452 does.
