I don't hike, jog, or backpack near as often as my friend in NW Colorado, but he loves J-frame S&W's. He packs a Model 37 when jogging, for self defense against humans and dogs that don't like joggers. He drew down on a pair of nasty dogs, just ready to shoot, when the the owner decided to get into the act to save his dogs. Wasn't going to call them off until my friend drew down. He packs a Smith 334 (Is that right? An Airlite .22 cal) on occasion, for small game. When in deep foothills, searching for elk stag, he packs a larger S&W 296 with a couple of shotshells for the first two, as he accidentally stumbled on a rattlesnake den, and didn't like the odds. He had about 20 rounds of .44 special (no shot loads at the time), and was surrounded by hundreds of snakes (it was April, I believe, and they were still hibernatingly slow, as he called it...he just passively walked his way back out of the area).
