IMHO handcannons in general need toned down. They are just so dominant I do not see a reason to use a primary rifle over a noobcannon let alone sidearms or SMGs. How I view it 120s definally need a nerf no question there. 140s and 180s maybe or maybe not I say buff primary rifles first while sidearms and SMGs definally need a range and aim assist buff. Sidearm and SMG buff cause not only are they both laughable out classed by handcannons their main competition is shotguns and we all know how stupidly powerful and "over tuned" shotguns are with Felwinter's Lie being a prime example and how stupidly broken the special ammo economy is where players can go a entire match using a "special" weapon as their primary weapon. I know people are gonna reply with how sidearms and SMGs have good chances in those extreme close ranges (that is highly debatable ATM with how dominant noobcannons are) but that is why most handcannons are paired with shotguns. So you have a primary weapon type that totally outclasses the 3 primary rifle types and a "special" weapon type that at this point is a primary OHK weapon that out classes the other two primary weapon types. Only reason I can see using anything else other than a cannon/shotgun combo is if you are actually trying to have fun with sad to say is becoming a rare thing in pvp now a days even in the so called "casual" play listings.
