On the 75B: The only thing I would like is to have a more positive (i.e. - harder) safety. Actually the Canik safety, while not as refined, gives a more positive control of the safety.
On the P01: CZ could spend a tad more time refining the DA pull. My PreB needed NO change in springs for the DA pull to be phenomenal. My transitional only needed polishing and a 17 LB spring. I normally find P01s to be plenty gritty, which adds to the perceived pull weight, and makes DA/SA harder. On OMEGA would be best on this gun - it normally feels better OTB, and the decocker is more ergonomic. Once again, CZ-USA: Please give us the P02.
