I tried one guiding bears for a 14” Mossberg 590A1. I really didn’t like it, as the gun wobbled and swung around far to much even when reined right in. I started dreaming up solutions and researching mall ninja gear that would hold it in place more so a guy could tolerate it for a whole season, but determined I was better served by a conventional sling or Velcro / quick backpack side setup. Don’t take my single experience as a reason not to, but when you aren’t expecting to shoot a bad guy at any moment, they’re rather a pain in the ass for hunting where you have to put miles on. Probably would be stellar in a tree stand though.
