Sure, it's a silly question. I really like my PCR as is- even the stock DA and SA trigger pulls.
Just bought a CZ-83, having missed my CZ-82 sold years ago. Their ergos exert a strong appeal for so many people, and along with having no plastic frame (+ compact size), describe why the 82/ 83 is my #1 favorite series of handguns. No exaggeration at all.
Had hardly thought about the fact that the 75D/PCR's factory grips have a subtle, Slight inward curving in the upper area for forefinger and thumb, which reminded me of the much more pronounced grip curves of the 82/83.
It's very doubtful that more pronounced (curving) grips exist for the PCR, due to frame lateral dimensions, or 75 grips which could have the 82/83 grips' --curves-- needing to be thicker overall (?) etc.
