For my Alaska hunting with grizzlies around,(hunting moose not grizzlies) I used an 870 with the barrel cut to 18 inches and a pistol grip. Attached sling swivels and a nylon sling. Very easy to have the gun slung over your shoulder (over a small pack, or under a large one) pointed down.It rides quite comfortably there, and you can grab it and pull it under your arm and forward, putting it into action without removing the sling from your shoulder. Of course, if one has time, would probably remove the sling from the shoulder for a little more freedom of movement. My next trip, I'll probably use my 44, as long as I know my buddy isn't too far away with his shotgun.
