Is it legal for citizens of a given state to sell/buy firearms from a different state? For example, is it legal for me (a Texan) to purchase a firearm from my friend in Louisiana? I know this is not allowed in liberal states, but how about free states?

Any pistol purchase from a different state has to be transferred through an FFL. So yes, you can buy a firearm from a friend, but that friend has to have it shipped to an FFL in your state. I think however, you are asking if you can you buy and take possession of a gun from a friend in another state which is a hard no. That would violate federal law.

A couple of weeks ago I had a caller at work playing the “I’m getting a pistol from my friend who lives in another state and how do I register it?” game. Told him federal law prohibits it, has to go through an FFL.

Then came the “what if I” B.S. from him. Once he starts different scenarios it’s evident that he’s a wannabe lawyer who has a fool for a client.

Finally told him to call the A.T.F and the State Police and ask them. Problem solved.

It's absolutely legal.

It just has to go through an FFL. All interstate transfers require an FFL. When my father in law passed we had to arrange FFL transfers for a number of his firearms that he left to my wife. It is up to the FFL what they charge for this service.
