Seems to me I watched The Best Defense or one of the other SD shows, and Michael Bane was on it and said he used a short lever action in his bedroom for SD. The show then showed some tactics on how to clear a house using a short SD lever action rifle. Looked like an inexpensive solution to me but I wouldn't encumber it with a carry sling that would just get in the way if one ever needed to use it for SD. If I lived somewhere where the risk of bear entry into my home was real, I'd have one handy in a major caliber.
