For USA Citizens:
Check with your local states laws for restrictions and requirements, then go to a gun dealer near you and purchase the firearm.
You'll be asked to fill out some paperwork and go through a background check to make sure you're not a violent criminal, wanted felon, mentally unstable etc..
After the background check is completed (it can take as little as 30 minutes in some places to a week in others depending on the store) you can take the gun home with you.
You have to be 18 years old, to legally own a shotgun.
In the UK you need a licence to own a shotgun,
In England you must be at least 14 years old to obtain a Firearms Certificate which allows you to own a shotgun. A shotgun can be obtained under the age of 14 with a Shotgun Certificate signed by a parent.
