I think that any adult who is mentally healthy should have the right to have a gun. When laws do not permit to people have guns we end up only criminals have them and that is not fair.
There's more to it than just mentally stable people having guns. What about people who are on the terrororist suspect list? You can't risk these people having guns. Ec convicts that have Spent x amount of years in jail. People who want guns but have emotionaly or mentally unstable siblings or family members. Background checks should include checks on anyone living with you because these people are also potential risks.
