Okay, I told a joke earlier, let me toss in a true story that will surprise you.
He's a six footer, and lanky, even for an old dude. He was hiking with a group and his reasonable good health and long legs allowed him to out pace them some so there was nobody with him when he turned a corner and came face-to-face with a bear. (I agree with what y'all are thinking - he never should have gone so far so fast but that's water under the bridge.) He stopped, kind of stunned, then waved his arms and hollered!
WHAM!!! That bear hit him so hard that he went flying, backwards and to his right, and downhill. Remember, now, there is nobody to help him. Fortunately for him, the bear took that hit as a win and meandered off. So, now he has to climb back up to the trail that the bear knocked him off of - and he is injured.
The point here is that, sometimes, no weapon can save you - you get that close to a bear where it can punch your lights out you are TOO DAMN CLOSE! My buddy was unarmed and in the wrong place at the wrong time as far as that bear was concerned. He would never have had time to deploy a weapon - that is just a fact of life in the deep woods. Sometimes, nothing can save you.
========================================
I will note that my two choices for woods walking are a .357 Magnum or a .45 Colt. I'm not much of a fan of .44 Magnums. And I would be carrying a stout fighting knife, too.
Even so.............up close and personal is just too close!
