The P-01 is outstanding, IMO. No, I haven't fired one, or even held one, but I own a rare CZ 40 P - which has the exact same alloy frame as the P-01 - and I like it's weight, and LOVE the feel of the grip. The only thing about my CZ 40 P is it has a slightly longer slide than the P-01, so it's not as concealable. Because of the longer slide, it's probably a tad heavier than the P-01, too.
I don't feel like I'd carry the SR9c over the PCR, they're both fine guns. I just already had the Ruger, so I opted for it when I carry a higher cap 9mm, and didn't bother buying a PCR.
I really like my CZ 75 compact (more or less the same as the PCR, but with a heavier steel frame), it is an incredibly well made gun, but not something I'd carry when there are better options. According to specs, the P- 01 weighs almost 5 oz less than the CZ 75 Compact, and the PCR weighs more than 5 oz less than the Compact. Doesn't sound like much, but it is after a day of carrying concealed. I should mention, though, the SR9c weighs another 5 oz less than the P-01. One other negative thing about the Compact - I have large hands, so the flat base plate on the mag sliced my hands. Had to buy mag extensions. Same problem with the PCR, I think. Oh, and I also changed the hard compact grips to rubber. Much better. I think the P-01 already comes with rubber, like my 40 P.
