They are pretty pistols.
Consider an aftermarket hammer from CGW or CZ Custom. Think about an adjustable sear from CGW to save time/trouble of working on the front leg/arm of the sear or the cam on the left side safety shaft to get the safety to work with that new hammer.
And there's that CGW match barrel bushing if your pistol needs it. Not all of them do, but you run across one sometimes that can benefit from it.
My youngest son has four or five center fire semi auto pistols. He takes two to the range. His CZ75 SA 9MM and his P07 9MM. He shoots a group out of the P07 (his concealed carry pistol) and then gives the CZ75 SA a work out. When I ask why he just keeps shooting the CZ75 SA he says, "But dad, you know I just like shooting small groups."
