My very first handgun is a Ruger Super Redhawk in .44 magnum. It goes with me whenever I am bear hunting, but never as my primary weapon.
I've been shooting this gun for 30+ years and have no worries about making a kill shot out to 50 yards. Whenever a bear comes in, I think "Why should I use this when I have a perfectly good rifle?"
Once in 2016 I was at bear camp in Maine and decided to go in with my revolver only. A small bear came in, but I decided it wasn't worth taking (probably about 50 lbs).
