That was long guns only. And in context is was a limitation to contiguous States.
So until 1986, one could take possession of a handgun purchased in another State only from an FFL in his State of residence, but he could take possession of a long gun from an FFL in a State contiguous to his State of residence. Since 1986, that contiguous State limitation no longer applies under federal law.
Note however, that the FFL requirement has applied to all interstate transfers since 1968.
