I voted yes, it doesn't take long, it is not really an inconvenience to wait a few extra mins for me and hopefully it keeps even a couple people from buying guns who are just going to cause problems with them and give the rest of us a bad name.
I know that they can get them anyways if they want but i believe that it does keep a couple bad people from getting a hold of guns.
That thought is enough for me to not care about a short phone call before i can buy a gun.
You can believe whatever you like. History and experience shows it to be wrong.
