Taking into consideration you are a US citizen and have a clean background...
You take an easy test, pass, wait, purchase/register the firearm, wait, and there you go. Each additional firearm you just purchase and wait agian (10 days).
If you are driving the firearm has to be in the front and the shells and clips (shells cannot be in the clip) have to be in the back. Or vice versa. You have to be on your way to or from a shooting range or a hunting ground.
CCW's are a little more work, but they are not impossible like everyone says. It all comes down to the way you present yourself to the sheriff and the reason you give of why you need to carry one. You have to take a class, give references that back up your good image, and then have a meeting with a sheriff in your county. There is a little more to the CCW (can only be reigstered for 3 firearms at a time, can appeal if you get denied, etc). Just look it up.
