Hmm, I shot P-07 - NO! I'd not pay $5 of my own money for one; or Phantom, or any Omega trigger based CZ handgun. And if I had one for free - it'd not see any of my trigger time. I'd let others abuse those all they wanted, as long as they didn't cost me anything.
P-01, P-06, PCR or HK P7 PSP are very nice CCW guns I'd be happy to carry. Small, light, simple, accurate... did I forget to mention - light and easy to conceal? I never shot Kahr thou.
Px4 - hmm, well... I've heard a little too many complaints from US/Can border guards about them, some of them went from G19 to Px4 and are NOT happy. I never held or shot one thou.
