Don't forget that the gun must be sent to the NC FFL by common carrier (UPS, FED-EX, USPS, etc.) rather then one of you carrying it to the NC FFL. The best way is to have a SC FFL send if to an NC FFL for you and then you can pick it up from the NC FFL. This is the only "legal" way that I know of.
As for long guns there is a SC law that restricts sale or purchase of long guns to neighboring states (NC and GA) so that overrides the Federal restriction. A bill was recently introduced in the SC Legislature to allow SC to follow the Federal guidelines rather than being restricted to NC and GA.
Lots of misinformation to clear up here.
1. There is no statute, Federal, SC or NC that prohibits the South Carolina resident brother-in-law from walking into a North Carolina FFL place of business and delivering the gun in person for transfer. He cannot give it directly to the North Carolina private party, but he is not prohibited from giving it directly to a North Carolina FFL.
2. If the handgun is mailed to the North Carolina FFL via US Post Office, it must be mailed by a SC FFL to the NC FFL because it is illegal for private parties to mail handguns via US Post Office.
3. The handgun may be shipped by the SC brother-in-law to the NC FFL using UPS or FEDEX, that is true.
4. There is no South Carolina statute which prohibits the selling of rifles and shotguns by FFLs to residents of any other state. FN1910, please show us where the South Carolina statute posted below
PROHIBITS anything. It doesn't. The Sourth Carolonia statute is a permissive statute that was required prior to the 1986 amendment to the GCA. The August 2004 BATFE Newsletter to FFL explains that this statute is no longer required, and nothing is prohibited by the statute. Please read it, the link is in post #6. The bill in the SC legislature is simply to remove a permissive statute that is meaningless. What prohibits the sale to residents of a couple of other states is the inability of the South Carolina FFL to comply with the other state's laws (such as the California DROS requirement).
We have enough problems with firearms restrictions that actually do exist in statutes. I hate to see members of the pro-gun group creating restrictions that don't exist.
South Carolina statute:
23-31-10. Purchase of rifle or shotgun in contiguous state. Any resident of this State including a corporation or other business entity maintaining a place of business in this State, who may lawfully purchase and receive delivery of a rifle or shotgun in this State, may purchase a rifle or shotgun in a contiguous state and transport or receive the same in this State; provided, that the sale meets the lawful requirements of each such state, meets all lawful requirements of any Federal statute, and is made by a licensed importer, licensed manufacturer, licensed dealer, or licensed collector.
23-31-20. Purchase of rifle or shotgun in this State by resident of contiguous state. A resident of any state may purchase rifles and shotguns in this State if the resident conforms to applicable provisions of statutes and regulations of this State, the United States, and of the state in which the person resides.
