I wish there was a CZ comparable to the Ruger LC9s. Alas, there is not, and likely never will be, so I bought myself an LC9s Pro.
Even with aluminum grips, the PCR (which is my favorite pistol) is still 26% wider than the fantastic (for CC) 0.90" grip width of the LC9s. With normal grips the PCR is 55% wider than the LC9s, which I'm sure is what kicked off the OP's idea for this thread.
Since it's never going to be my carry gun, I leave the normal-sized grips on the PCR for better comfort at the range.
