Exactly.
Then there's just the physics involved in rifle bullets, wound channels, etc. etc. and the same with pistol bullets. Rifle will out penetrate, hit harder, do more damage than a pistol bullet. Pure physics.
I take the rifle, every single time, and twice on Sunday over both a shotgun or pistol in a bear charge situation. If you don't have time to use the rifle, you aren't going to have time to use the pistol either.
The absolute best tool that we have, is that 11 lb melon that sits atop one's shoulders. Making good decisions in bear country is going to save a person from finding out if their pistol skills are as bad ass as their typing skills on a computer.
