Adding my 2 cents worth on this subject, recently switched to the glock mod 20, I live in AK and bears are a potential threat. Used to switch between different handguns for people or animal defense but either can happen anytime so wanted one handgun for ccw and bear defense. Settled on the glock mod 20, carry magazines loaded with 220 buffalo bore hardcast and 135 corbon hollow points, quick change of magazines and am fairly well prepared for either situation. Never was a glock fan but after using it as a duty weapon for many years it has earned a grudging respect. Did change to the pyramid trigger system. Personally don't see much use for a revolver in 10mm, but to each their own.
