I didn?t get from your question that you were using it in competition, so if that?s not what you need it for, you should check the P-01, SP-01, and 75b(d). The P-01 and SP-01 use different manufacturing than the 75b series and are alloy framed. They are in theory better spec?d for reliability. The 75b is all steel and heavier. It shoots very nicely and in my hands is 100% reliable. They?re all really good, so if you like CZs you might end up with at least two, if not more, so you should pick based on what you want it for and what shoots the best for you.
I can?t speak for the competition variants but I believe they?re all variants of the SP-01. You can have a standard SP-01 modified for legal use in some of the competitions. Look at Cajun Gun Works (they made mine smooth and accurate as butter and vastly improved the trigger and extended the mag release) or CZ Custom. Not that you can?t do the same with the others but the SP-01 seems to have the most mods easily available to my knowledge. Other competitive shooters I?m sure will chime in on that.
IMHO you can?t go wrong with ANY of the CZ models.
Maybe for more targeted feedback you can say what you want to do with it.
