The Army was interested enough in it to order more for additional testing. By the time they did, DWM turned the Army down, perhaps because they had already signed a contract with the German military. Whatever the reason, that pair of Lugers remain the only two ever made in .45 ACP. The whereabouts of one is unknown. The other was sold for a $1,000,000 in 1989, although when it was auctioned in 2010 it brought "only" $494,500. So it's really the "almost-half-a-million-dollar Luger," but it does exist.
