I am about as pro-gun as it gets, and I think this guy is an idiot. In my opinion he forced a situation that didn't need to happen.
He is also got lucky when the moose dropped. There was a good chance that the Glock would have just pissed off the moose. Most pistol calibers have no where near the power needed to drop an adult moose. Usually the right tool for protection in moose country is pepper spray and/a big bore rifle. I usually carry a Marlin 1895gs 45/70 in moose country as a last resort.
Does anyone know if this guy got charged?
