P-01 vs 75D PCR...
Size/dimension wise they are basically identical guns (think the P-01 is an oz. or so heavier)... Regarding looks, the P-01 like the SP-01, has that 'squared-barrel' look, where the PCR has a 'mini' 75B look...
Shooting these guns, recoil is similar, however I feel that the P-01 (which I own) was MORE ACCURATE for ME!!!
If you're looking to buy one, the P-01 is CZs newest 'state-of-the-art' service pistol which has passed all of the rigorous NATO testing. For me, the P-01 has a perfect 'hand-fit' and is one of the most accurate pistols I have shot. I think the guns are very similar, and in the end, it's YOUR preference for looks and feel... either one is a great choice!
