Many years ago I killed a charging black bear in my back yard at my Alaska home that looked about the same size as this critter. I used a Galil semi-auto rifle in .308 Winchester loaded with 150 grain soft point bullets. It took four close range shots to stop it. That was more excitement than I ever hope to have again.
Apparently a peace-loving Islamic bruin isn't safe anywhere from you infidels.
Seriously though - so many shots from rifles just shows how iffy handguns are against bears no matter the caliber. But way better than nothing.
Is your Galil a brass smasher? Mine sure was. I traded it in for a milling machine.
