Add a light (for low to no light) and/or green laser (all times at self-defense distance) and you can easily shoot from the hip w/ little practice. W/ practice, you can fire from the hip and/or point shoot w/ not a lot of trouble...
That said, if I were in bear country, I'd want at least 7.62x39 (or 300 blk) over 5.56 at close ranges, but YMMV.
