Thanks, I was playing dumb to see what his response was going to be.Unless I have missed information in life, these are the basic rules:
* In your home state, you can generally buy guns of any type from a private party, or a dealer (rules vary by state though, so this is true in OK at least).
* If you are traveling out of state, you CANNOT buy guns from a private party legally.
* If you are traveling out of state, you CAN buy long guns through a dealer/FFL but MUST go through any state specific processes for the state you are in. For example, an OK resident can buy a rifle in Florida, but would be subject to the waiting period for it.
* If you are traveling out of state you CANNOT buy pistols through a dealer/FFL.
* If you are buying a gun from out of state, it MUST be transferred to you via an FFL in your state of residence.
* There are no known exceptions for "neighbor states" as these are federal rules.
Note that these are assuming all purchasers are of proper age for the item being transferred/purchased, and have no disqualifiers from owning such as a felony conviction, domestic, drug use, etc. And this definitely doesn't cover NFA items.
