Where many states require consumers to present a permit to purchase a firearm, South Dakota does not. Although you must carry a permit if you intend on having a concealed weapon, it's relatively easy to purchase a gun in South Dakota.
According to the South Dakota Constitution citizens in the state will never be denied the right to protect themselves and their property using firearms. A permit is not required when buying shotguns, handguns, rifles or long guns.
Firearms can be purchased from federal firearm dealers. A list of locations in your area can be found online. When you go to buy a gun a 48-hour hold will be placed on your purchase so a background check can be completed. If the background check clears, and the buyer is 18 years or older, the firearm will be issued.
If a minor wants to buy a firearm, he can do so in the presence of a legal guardian or firearm instructor. Anyone who has been convicted of a misdemeanor must wait at least a year before purchasing a firearm and a convicted felon loses his right to ever carry a gun.
