While I don't mind if others open carry I prefer to keep my gun out of sight. The problem with carrying with a pack if you carrying on your right hip is that the pack waist strap covers the gun. I have been thinking about a chest holster of some type that could go under a loose fitting short sleeve shirt, but other than "thunderwear" which looks like it would be hot and get soaked in sweat had not hit on anything. Thanks for posting the hill people info the snubby kit bag looks very interesting for a small 9mm.
