Hallo Rolf,

How about one of these: http://www.egun.de/market/item.php?id=5308224

At 1020mm overall length it is about the same as the H&K with suppressor, and you have the longer barrel with improved ballistics and sight radius, plus a "Sauhammer" of a caliber. I don't know what the H&K costs, but I don't imagine it's cheap. The few which are available used here (they haven't been imported since 1986) cost close to $3000. A Doctor sight or a low powered scope would complete the outfit.

Plus, since Marktoberdorf is only about 100 km away, you can carry on the transaction face to face and actually handle the gun before you pay for it.
