W.D.M. Bell mentioned in his "Wanderings of an Elephant Hunter" bringing a C96 pistol with the stock holster along on his hunts. May not exactly fit your "adventurer" examples as a big game hunter and guide, but it his interesting to read his accounts of using it. Describing an encounter with some locals who were trying to prevent his group from watering their animals, he wrote "Seeing some flourishing of spears going on among the others, I began pasting dust about them with the little Mauser. Seeing no smoke again, yet getting whing whang right and left of them, they turned and bolted. I got in another clip of ten and kept them dodging dustbursts for 400 or 500 yds."
