Nope, handgun would need to be shipped to an FFL in your state of residence.
You are right, I'm wrong, kinda. I think I'm write about how it's written in SD law, but not Federal.
Federal law strictly prohibits the transfer or receipt of any firearm to a non-resident by a non-licensee... Rifles and shotguns are treated somewhat differently from handguns, and federal law does not prevent a qualified citizen who resides in another state from purchasing a rifle or shotgun in a face-to-face transaction with a federally licensed firearms dealer outside his state if: the purchase would be legal in both states, and if the regulatory requirements of both states are complied with. 18 USC 922 (b)(3)"
That being said, let me twist this around and pitch it back. So you can't sell a handgun to a non-resident. Okay. Let say someone from SD comes to Iowa with their personally owned handgun and sell it to an Iowa resident. They wouldn't be selling to a 'non-resident' who resides in another state. I assume I know the answer but thats why I ask questions.
