Six percent of people think they can beat a grizzly bear

why wait until it charged to fire? why not fire when it was slowly stalking?
Because a glock 27 only holds 9 rounds and that dude was going to need every one to have a chance. I applaud him for knowing his limitations.

I do feel bad for him though. Now he has to either claim the mountain lion was tiny or admit how terrible he is at shooting.
