Seems like its like this in most States. I know waiting periods are pretty common (pay today, but don't get possession or the firearm for 1-4 weeks).

It also seems like mail order of complete guns directly to a residential address is pretty locked down (I know 80% guns and such have loop holes). Its my understanding that you've got to have it delivered to a licensed gun dealer, then you can collect it there where they're can do any requisite ID / document checks. Bet this varies state by state though, as well as the bar for constituting a "licensed gun dealer".
