Man, I must need new glasses, because I missed the INTRA vice INTERState.
I still say however, that the Feds are involved in a within State transfer based on the fact that you fill out a 4473. Unless, it is a totally private, within State purchase between two private citizens. If that is the case, a CC permit would not matter anyway.
If it is a within State purchase from an FFL, a NICS/Brady check is still required unless you are in one of the few States which accepts a CC Permit as an alternative. If I am reading your location of W. PA as Pennsylvania, they do not. Additionally, I doubt that it can be lawfully accomplished via mail or other commercial carrier.
