Seems to me that other than weight, a pistol GL/SSC in one of the more thumping calibers like .300BLK might be a good backwoods gun. You have the punch of the rifle-caliber round in a more agile package, and the 37 can launch smokers or flares up into more visible positions in a SAR situation. I mean, ain't nobody gonna confuse Goofy Grape for anything natural...
