How hard is it for a private citizen in the US to get an FFL?
Here in Canada, all I need is a PAL to sell/send a firearm through the mail or FTF, but the buyer must have a current PAL as well.
Possession and Acquisition Licence (PAL)
It isn't hard to get an FFL, a routine background check by the FBI like anyone in the military has to pass to get a security clearance.
