OK, this will be the last website I recommend today, but this one belongs to a good friend of mine in Denmark, Mr. Per Jensen. Per is very interested in Luger research and on his website, he has a very interesting, true story, about a silenced Luger. Take a look at his site and click on the box labeled "Luger Reasearch". You will enjoy this true story.
