Those deals tend to come, sell out, and not return. Some big European agency upgraded it's armament and their old stuff is sold on the international market. Basically the same thing as happened with various country's military armament and gave us all the assorted milsurp rifles from around the world.
The bigger the agency or army the more we get; eventually they all dry up.
There seems to be a lot of S&W ex US police agency pistols on the market now in both 9mm and .40 S&W. Those who missed the P6 might want to look at some of these because they're generally fine solid and reliable handguns sold for a fraction of their new cost. Many of them are hicap pieces with either 12 or 15 round magazines. Many are DA/SA with decockers too, which to me is a very sensible configuration in a carry pistol. I'm seeing them in the $250. - $350. price range practically everywhere that I look.
