Instead of reducing the Sawed-Off's range or spread, I have a better idea.
Epic intended players to be using the Sawed-Off defensively, but that's clearly not the case. We're getting instances where people are bum rushing towards power weapons or other players in a jihad manner and then letting the thing rip. Epic intended the weapon to be a COUNTER RUSHING weapon.
So how about a longer delay after rolling or roadie running? How many times have you shot someone charging at you seemingly a million times with your Gnasher only for him to roll right up to you and blast you to pieces while you were rolling away?
Now give me my Nobel Peace Prize!
