I'm planning on doing some backpacking up North this year. I haven't backpacked in an area with dangerous wildlife before, so I've always just pocket carried a small gun. Now that I'm going to be in a slightly more risky situation, I'd like to carry at least a .357 revolver while backpacking. What holster do you all find comfortable while carrying a backpack? I typically backpack fairly light and carry a 45 liter pack.
