This thread has been informative with a healthy level of discourse. It’s good to challenge traditional thinking, especially my own. The biggest realization is what you think you should carry in terms of “enough gun” compared to what you would be capable of effectively using in a life-threatening, heart pounding circumstance.
I own a Bisley Blackhawk convertible that can be “loaded for bear” with .45LC +P Underwood hardcast but, could it be drawn quickly, fired multiple times, putting lead in vitals against a charging predator? I have my doubts. I also own a 625MG which handles normal .45LC hardcast and has a reasonable DA trigger pull. I feel my chances would be a little better.
I think the best chances of a “successful defense” for me based on my training and competitive shooting would be afforded by a G17/20/21 or a 1911 TRP or DW Kodiak.
