I could be totally wrong, but I figured the G3 was the G2C, sized up. I doubt they'd make a compact version, of a compact gun that they made bigger. However, I would LOVE to have the G3 trigger in the G2C. Or at least, just the better trigger safety dingus. My G2C still binds a little bit there. Aside of that, and forward slide serrations, they're the same gun, FTMP.
