Both good choices. The PCR has a better trigger from the factory and is lighter for carry.

I too battled this issue and decided on the PCR as it will primarily be used for carrying and I wanted as slim a profile as I could get. I ordered a PCR (over a SP-01) for the very lame reason that a short dust cover looks better to me, and, as well, I prefer a 75 over an SP-01. I'll never use the rail, so it's all about aesthetics for me. I guess I just like curves!

for me the CZ75 PCR because I like the classic lines of the PCR now if you are ever going to suppress it the easy choice is the CZ75P01
