Take for instance the CZ 75 SP01 Shadow Custom (black 91030, or duo-tone 91031).
Below is a list from CZ regarding what they do to 91030 and 91031 versions. My question is has this list ever been different in the past? Meaning, would there be a difference between new in box 2015 versus 2018 made SP01 Shadow Custom?
Thanks for your help!
