i have killed many deer using buckshot . 3" mag using a ported buckshot tube. all of them were running deer with dogs however i wouldn't hesitate sitting in a stand with buckshot as long as your shots are 60 yds. or less
both sportsmans warehouse and Academy sell em for $399 . but they dont keep em long . both said they usually sell the day they arrive. Palmetto state armory had a .40 cal shield for $409 on sat. i have the 9mm and love it.
