Honestly wait until the December patch. Right now handcannons are garbage and I'm a die hard handcannon user. The reduction in their range severely nurfed accuracy also. As it stands you can have shots perfectly aimed and in the perfect range and thanks to rng you miss. Sometimes ..m OK quite often this can happen multiple times in a row. Usually resulting in your death and your opponent taking minimal if any damage. The December update is increasing handcannon accuracy so hopefully they will be viable again.
