However, for the seemingly "new" fad of MASS killings, the shotgun is sorta unbeatable.
No, they would ban shotguns too.The bad guys could turn to shotguns and them lawmakers would wish they had the old semi rifles back again.
I started to make the case that an AR beats a shotgun for someone intent on committing such a crime. If you are familiar with shotguns and AR's, you can figure it out for yourself. I'm not going to make the Anti's case here.
I very much disagree.
I suppose a short barreled shotgun might spread out the shot even more
Using slugs takes away the shotgun's only advantage, which is multiple projectiles per round.Skans; rifled slugs? I imagine they'd work pretty good within the distances of a city fight.
