Eh I think it will still be needed. I think they are trying to emphasize that hand cannons are best at short to medium range and do very high damage up close. The lower mag may actually help depending on your perks.
it wont help the fuqing last word
Maybe not. I don't use hand cannons I'm just going by the perks i know some have. Unfortunately though that's how it works. Everyone uses the guns because they are very OP. So they get nerfed a bit. If it's too much they'll buff em again until everything is about equal
