Came across a guy who looked like the stereotypical REI catalog outdoorsman while hiking. Everything appeared status quo for this mountain trail except for the Mossberg short-barrel 12g clipped to his backpack. We briefly chatted at the trailhead about his setup. http://www.mossberg.com/images/Mossberg_Guns/930/NEW/50440.jpg had two nylon straps with lightweight buckles which clicked into the receiving end attached to the front of his backpack's harness. He said the barrel end buckle is undone when he approaches other hikers and drops the shotgun back/behind his right leg while turning his body away so as to not expose his shotgun as much. Asked about the weight he said it was "nothing" and compared it to a gallon of water or extra camping gear. It was a very sano setup for this week-long hikes into the high country.
