There’s a make and model of pistol I like that doesn’t bring too terribly much these days and a collection of nine are coming up for auction. I will place bids in advance on all nine, and the reality is I might win one or none. But, if the stars align, and I end up with all nine, they are shipped from the auction house across state lines to my FFL in Pennsylvania. What are the implications, if any, of purchasing nine at once? I’ve limited purchases of pistols to one at a time, these days maybe one a year, at best, so what red flags would this raise? State police? Other?
