I have the Kadet,,,
I purchased a CZ-75B and a CZ-75B Kadet at the same time,,,
Both have performed flawlessly for me.
The logical reason to spend that much money on a .22 pistol,,,
Is to have a cheap shooting companion with the same feel as your 9mm pistol.
Or you can justify it by saying,,,
"I wanted it."
I can't tell you if you should do it or not,,,
I can only say I am glad that I sent the cash,,,
Inexpensive practice was my goal and this makes it possible.
