Walt, The CZ PCR is considered a compact by name. CZ did produce the CZ 40P, which is the same size as the compact 75B and PCR. It also has the same, alloy frame as the PCR/P01. There is question on how many they produced, but I love mine.
I should have been clearer. A 75B
Compact and a 75B
compact denotes two different type of guns. The Compact was a steel-framed gun with a safety, while all other 75B compacts had alloy frames and decockers, with one or two exceptions (which were short-run models.) The frames of the steel and alloy models looked similar, but were subtly different. The 40B was classified as a compact, too. (That's one CZ I let get away I regret letting go, but I had an offer I couldn't -- at the time -- refuse.)
The P-01 and 40P you describe above all came out a number of years AFTER the CZ-75B Compact was first introduced,
and long after the CZ-75B Compact in .40 was supposed to have been produced but wasn't. (Surprisingly, there were also a few CZ-85 Compacts produced back then, with ambi-controls and a safety... and a handful of 75B Compacts with alloy frames. I only personally know of one -- owned by a member of the CZ Forum.)
When CZ finally brought out their .40 versions of the various compact models, they had big problems with their compact mags, which is probably why the 40P used full-size mags with a spacer. The original .40 mags wouldn't function properly and the early/first "fix" was to modify the mags slightly and reduce capacity a bit.
I never really found out how that issue was resolved. I also don't know if anyone ever tried the Pro-Mag .40 compact mags in a .40 compact CZ, but I'd bet they would have worked fine.
The 40P used a 40B slide, and a frame based on the
P-01 frame that had been modified to work with the 40B slide; the frame looked the same as the P-01 frame but wasn't. The PCR frame was different and the earliest ones weren't forged (like the P-01). The slides from the PCR or P-01 guns wouldn't operate on the 40P frame (or vice versa), and the Kadet Kit wouldn't function on the 40P frame, either. (I think a few people claimed to have made the Kadet Kits work on a 40P lower and a 40B lower, with some tweaking, but I never saw that confirmed.)
