Thanks for the link. There are so many nuances to these things. I noticed in the article it said the DOJ has been rejecting split party transfers lately. So maybe on or off roster is becoming a moot point.
The last FTF PPT I did a few months ago, the FFL had me buy a new lock from them even though the one I had was identical - it was just a different mfg. Always something.
Thanks for the advice. So guess I buy local or plan a 10 day vacation.
