Look at the amount of crimes committed with guns, gun related murders. Im ready for wheelr to come with "outlaw guns and only the outlaws have them", but that doesn't really hold much water. Over half your homicides are gun related, you can't argue the availability of guns has nothing to do with that. The percentage of which guns are used in self defence is under 1% of crimes relating to guns so the guns for self defence doesn't really wash either.
I have no problems with stricter methods to obtain guns, but that really doesn't matter with criminals and most crimes committed with guns, considering most of them are committed with unregistered, illegally owned guns.
I believe that the 2nd Amendment is still valid on the grounds of protecting the other amendments and for militia use. If one day people don't like the government and there are enough of them to take power and overthrow it, then there is the majority speaking, and guns will help that, and I support it.
I think they should have stronger methods for controlling who can have guns, based on medications being taken and what not, but not on what kinds of guns you can have or what any crazy politician wants to label an "assault weapon" for their day in the sun.
