Still hurts, if only from the point of view of a collector, to see something like that happen. If nothing else, it means that the pistols will be all the more expensive to purchase legally. I've limited myself to East German models, because they're cheaper than their Russian counterparts. Events like this just price the Russian models further and further out of my range.
Somehow I doubt that the situation is as black and white as "if they're not destroyed they'll be sold on the black market." Such situations never are. There are perfectly responsible ways to sell firearms to reliable people. Companies in the US would have stood in line to import those pistols, because they know that collectors, like me, would love a shot at them. These import companies are perfectly legal and monitored by the government. Where's the evil in that?
