Yes you wouldn't think this change would be enough - because if you want to get a gun you can but for some reason it has.

1 & 2: Licencing and checks stops people with a violent history purchasing/owning guns legally. If that personality decides they need a firearm to hurt people there is a month+ between their desire to do harm and actually owning a firearm.
3: Compulsory safes (and the police check each owner has an appropriate one) reduce the likelihood of a person accessing anothers firearm.
4: More dangerous firearms like handguns and semi-auto are harder to get yet again thus less prevalent stopping what might be a small shooting from becoming significantly larger. A significant shooting becomes much harder with a double barrel shotgun than an AR-15.
Another benefit I imagine is restrictions would stop police feeling there is a potential firearm around every corner and may help calm down ongoing US cop shootings/mentality too.
