One more thing to add, based on my own experience with the Compact vs. the PCR. Yes, the extra weight of the Compact makes it a real bleepcat to shoot, but the contour of the beavertail is such that it was eating a hole in my hand after less than 100 rounds. The PCR doesn't do that, there's just a little different contour and upsweep. Of course, that could have just been me, I don't think I've seen anyone with the same problem.
I don't know about the others, but my PCR trigger wanted to bite, I replaced it with the CGW 85C style, problem solved. I went with the PCR as I have no need for the rail and I have decockers on all my pistols. I also prefer the "Classic" CZ action vs. the Omega, but again, that's just my own opinion. Good luck.
