while doing some research on my pistol, I noticed a "Collector" site selling what they claim is a K.M. Luger. They even reference the book "The Dutch Luger" to back up their $8500 price tag. I called them and informed them that according to the book they reference, no K.M. Lugers were produced with 2xxx serial #'s, and especially in 1937. Additionally, it would have a DWM toggle, not a Mauser. They didn't want to hear it, and still have the gun for sale. See for yourself at
