Find a picture of a bear in "charging mode" and enlarge it to full size, with particular attention to the face on that picture, with particular attention to the nose on that face. Set this target at 30 yards.
I am told that a bear can lunge as fast as 40 m.p.h. (58.1 f/s) for short distances. I don't really know if 60 feet is a short distance for a bear, but I would bet that it is. This gives you 1.033 seconds to draw and fire at least one shot into the bear's nose (but let's say anywhere in the face within a 2 inch radius of the nose.
But not just ANY shot. It must be a shot powerful enough to smash through bear snout and bear skull and lodge deep enough into its brain to turn off the electricity (thus motor nerve impulses) almost instantly.
Let's say, no less than 200 grains, hard cast, at no less than 1000 f/s from the muzzle.
This means a hot .357, a warm .44 Special, a warm .45 Colt or .45 A.C.P. +P, and certainly any .41, .44, or .454 Mag load worthy of the name.
Try this exercise, 50 shots worth, with every qualified caliber to which you have access. If you can do it 45 out of 50 times, you can probably defend yourself from a bear with a pistol. If not, it's probably Mossberg (and bear spray) time.
