you can buy directly from an individual in state, buy a C&R gun directly with your C&R license or have a class3 dealer handle the transfer for you. Whichever way you buy it there are forms(form 4) that need filled out(in duplicate) along with fingerprint cards, photographs and law enforcement signoff. There is also a $200 excise tax that needs to be paid, some people think of this as a license which it is not, it's just a tax stamp. There is also a citizenship certification(simple), 4473 and a NICS check.
