We were charged one time by a grizz in the Thorofare. I had my spray on my hip. My guide already had his pistol out and started firing at the bear as he closed in. I was layered up with jackets. By the time I finally got my spray out, the bear had turned and was headed back into the trees. Glad I saw this thread as I recently picked up a G20 in 10mm. If you've never been charged by a bear, you don't realize how quick they can cover a short distance. I'll be getting one of these chest holsters...
