Yeah, I think it was implied that the MF is heavily modified to significantly expand the capabilities of the base ship. So maybe the stock automated cannons were replaced by manual but more powerful versions.
Having blown up a tonne of them in Tie Fighter, the stock YT-1300 basically had all the fighting ability of a cabbage. The only real thing to be worried about was ramming them by accident, or possibly laughing too much to rebalance your shields.
So yes, I'm pretty sure the Millenium Falcon was heavily upgraded.
