I suspect that the brass grabbing the chamber walls is not critical in a recoil operated firearm such as the Luger. The barrel is short and as soon as the bullet is out of the barrel the frame is moving back. Unspellable, who really understands this better than me will probably be heard from on the topic.

I would hazard a guess that the chamber walls are slightly oily from normal barrel lubrication. My guess is this is not going to disappear too fast as the chamber walls are not exposed to the majority of the combustion gases.
