The focus is currently on assault rifles: semi-automatic (full auto is already illegal) with large ammunition/clip capacity. Specifically the ones that can fire 20-40 rounds in about 8-20 seconds.
Shotguns and revolvers are not the focus at this time.
Only the guns owned by honest, law-abiding citizens. The criminal element would not be affected.
So called "assault weapons", automatic weapons. The criminals will not be concerned with any such laws.
Anything semi automatic. Check out what Illinois is trying to do.
