For quality..they are pretty much the same gun...just a size difference. The PCR is a very high quality gun. Same sights on the Compact and standard B' models. The PCR's Novak style sights are a better sight than the standards, IMO.
As far as accuracy is concerned they are both way more accurate than me. My Compact was every bit as accurate as the fullsize guns I have shot and I hear the same things about the PCR. Shoot well
