First: Internet firearm sales. Anyone purchasing a firearm over the Internet, either from an auction or private sale must have the firearm shipped to a federal firearm dealer. A background check must be performed before the purchaser can take possession of the firearm.
Second: gun shows. All federal licensed firearm dealers complete a background on all sales as if they were in there gun shops.
Third: private sales. At the present time there is no way for anyone selling a personal firearm to do a background check, therefore it is not required at gun shows or anywhere else in South Carolina. However, a private seller cannot sell any firearm to a non-resident of South Carolina (proof of residence must be shown).
Private sellers at gun shows are usually collectors selling or trading guns to increase or decrease their collection. Most of the privately sold guns are old, do not use modern ammunition and are usually very expensive. I have seen some sell for over $8,000. They are not the Saturday night specials. At the gun shows that I have attended or participated in, private sales accounted for less than 3 percent of total sales and 97 percent get background checks.
