IDK for a carry gun its pretty awesome as it is (although my RAMI gets more love in this role. Maybe all it needs is a tad lighter mainspring to help DA pull and hardened firing pin retaining pin to replace the roll pin.
I recommend getting a second CZ, perhaps a full size 75B or SP01 and doing your described mods to it for the ultimate fun at the range. A heavier gun will be even more steady contributing to accuracy.
It is a free country, however. You can see your intended mods on my post in the 85B section with pictures if desired. I'll likely get a chance to send some lead down range this weekend before I report back to CGW.
