I'm in alignment for Version 2.
Freedom of guns are a-okay. But, obviously they cannot go unrestricted.
I'd feel safer as a person to be carrying a gun, not because of the intention to shoot the first criminal I see, but rather as a beacon of warning. If someone sees you with a gun, you're less likely to be mugged/robbed due to basic concept of the risk/reward factor.
Furthermore, if such unfortunate circumstances do occur, you have something to defend yourself with. A gun does not necessarily have to kill. A shot to the leg should suffice, you remove their mobility without killing them.
Restrictions however, should be applied to limit the chances of a crisis. Though, no matter what action we take, preventing a crisis involving guns would be almost impossible, even with the complete ban of guns to civilians. (Which could happen through smuggling, theft from authorities, black markets, and people can create their own guns, too. There's probably more methods, but this is all that I can think from the top of my head)
