I see you are in Louisiana. I was an agent in the New Orleans office of the FBI when the discontinued 1076s were offered to agents with the stipulation they could never be approved as duty weapons. $300 got you the gun and two mags in the original box.
I had an FFL (which S&W required) so I became the 1076 guy for the office. I collected the dough from everyone who wanted one - agents, cops, clerks, everybody. I sent in a big envelope with my FFL and a motley collection of checks, cash, and money orders.
One day the mailroom called me and said to come to the loading dock. There was a whole big ol’ pallet of 1076s there. I spent the next two days doling out guns and trying to get 4473s back. Some were for guys all over the state.
I think New Orleans has a pretty high ratio of 1076s to the general population. I’d be interested if the letter shows it was shipped to me.
