If you can conceal the P-01, that'd be the way I'd go. And there is more difference between the P-01 and the PCR than what's been said. It's not just the rail on the P-01. The PCR's frame is cast aluminum. The P-01's frame is forged aluminum. I would definitely choose a P-01 over the PCR and it will be much more enjoyable shooting at the range than a sub compact carry pistol. I've owned and had a great deal of experience with the P-01 and the only pistol that really compares is the hard to find SIG/Sauer P-228.
