Calling all people smarter than myself. I have a quick question. I've been looking at buying a new Scorpion Evo 3 s1. I've seen used scoprion evo pistols from 2017, 2018 for sale. Is there a difference between the 2018 version and the 2021 version. Have they made any updates/tweaks? Or are they the same? I know some gun companies update guns throughout the years. I remember hearing something about the CZ scorpion mags being messed up and CZ fixing them years ago. Was wondering if the same thing happened with the actual pistol. Thanks in advance. I tried googling it, but couldn't find anything.
