A college buddy is a Special Agent in the Secret Service. He personally saw their firearms collection at their Maryland firearms training facility. He almost passed out from shock! Everything from Derringers to 20MM cannons! If the POTUS travels to Africa, they even have .375 H&H, .416 Rigby and other "elephant guns" readily available. Who has the better collection, ATF or the Secret Service? Let the fed LEOs fight it out for bragging rights!
