Mass shooting in Las Vegas. 50+ dead

[A Theist]

After the events and discussions of the last few days, I'm wondering if semi-automatic rifles ought not be banned. Hunters can use bolt-action. Thoughts?

I'm more interested in something for home and personal defense. For close quarters and in narrow hallways something along the lines of the Taurus Judge or the S&W Governor is all that I'd need. Both guns shoot a variety of 410 shot gun shells as well as a 45 ca. bullet. Much more maneuverable for home defense than a 12 ga. shotgun or a rifle.
