Look, I started with a Ruger 22/45. It didn't take me a couple months to get bored with it and start looking for a centerfire.
I would go ahead and get a 9mm from the start. CZ makes the Kadet slide for about $300 if you desire to shoot 22 at a later date, and it fits on the P01.
Much as I really enjoy the CZ Kadet, I wouldn't pay $500 for the dedicated pistol. Quality piece but...it's still just a 22. If you absolutely must get a 22, I vote for the SR22.
