I have looked into an NP-22 myself and have been advised against it.
The Chinese "alloy" frame is suscepable to damage/failure, much the opposite to the CZ clones which are built like a tank.
I own a NZ-85 (9mm) and an NP-40 (40S&W) both are CZ clones, both are very well built and have put 1500 rounds thru the .40 and 600 rounds thru the 9mm, all without a hiccup.
If you want a good 9mm Norc, I suggest the NZ-85. Their High Power clone is crap, had one and sent it back.
The Norc 1911 Commander is next on my wish list.
