My solution :
#1. Bear Spray
#2. Rossi Ranch Hand loaded with HOT .45 Long Colts on a hip/leg quick draw holster (

#3. My Cold Steel Gurka Kukhri. It's not JUST bear defence, it's my Ax, my camp knife as well. (and no I don't intend to cut a bear in half with it, lol - I WILL use it to stick into something chewing on me or charging me.)
