turkey guns
My long time 870, and the Moss 835, both have slings, and stay slung alot during turkey hunts. Gobbler hunting not a jump shooting exercise of course, and you sometimes can cover a lot of ground. Oppositely, toting a blind, folding chair and what every else too a long sit, the sling is a big help too.
I made these slings up from SKS/AK green web slings, simply sewed on two sling swivels and a buckle. Cheap, and works for a variety of long guns.
