Wow, you went all-in on CZs. Good job dude!
The biggest trigger feel difference in the P-07/09 will come from a lighter hammer spring. If these are range-only guns and not for defense, you can try springs down to 13# (OEM is 20#). I use 15# in my carry guns. However, that will require a CGW extended firing pin kit. It's fairly easy to install this yourself, but requires a punch. Break-in and lubrication will make a difference as well. The CGW ProGrade kit is a very nice addition, and I have it in both of mine. I like that you can tune the SA pull separately from the DA pull so that it remains close to the OEM weight for carry.
The Shadow2 is the best gun I've ever owned, and reaches perfection with a few aftermarket parts and springs. If you're able to do a detail strip of a CZ75, you can install these yourself. I have a parts list and link to instructions if you're interested.
