in most states yes in NC for handguns they are done by the sheriff (CHL or PPP) long guns are at ffl

Usually yes, though it may vary from state to state. The background check is usually fairly easy so long as you aren't hiding from the law or partaking in anything illegal. Also, be prepared to pay for the background check, most places charge you for them. If I recall correctly it'll cost about $20 to $25 dollars.

Gregg, yes Sir unless you have a Concealed Carry License. Stay safe!
