Luger and General German Handgun question

[jussi16]

My late great uncle told me that he had two small caliber pistols on him during the battles.
He was a machine gun shooter (maxim). He told that it was so heavy to change position during the action, so sometimes he had to shoot "a couple of soviet soldiers" while doing that. If they got too close.
Actually he was called cowboy because of those two pistols.
