I don't see how you can realistically have either of these extremes. In Ireland handguns, with the exception of a particular class of law enforcement and competition .22 calibre guns, are illegal - period. You can buy firearms but it's a very drawn out process and the ultimate decision lies at the discretion of your local police Superintendent. There are still murders committed in Ireland with handguns between rival city gangs but the common mugger will not have one. Do I feel safer? Yes
It seems that Switzerland has a low gun-crime rate but I wouldn't be so quick to give credit to their gunlaws for this. Switzerland and the United States are very different places.
Again this is just my $0.02
