I have read this thread with a high degree of interest, and actually tried to think this through.
Under normal circumstances, I would normally be in total agreement with the OP. However, since May '07, my life has redefined "normal". My rationale behind carrying has been forever changed, and comes from my role as a disabled, custodial dad in a world where the potential threat of robbery or muggings has been replaced by spontaneous riots and terrorism. (Disabled meaning a damaged arm and two damaged legs ... running is definitely out of the question.)
Chances are good that if I find myself in a situation where I have to exercise my CFP, there is an 80% or greater chance that my younger children will be present, in which case, my job is to keep them safe. Chances are that I will need to provide cover fire until I can get my children under cover, then some degree of direct precise fire to neutralize the immediate threat. My semi-auto pistols are single stacks, and can provide 7 to 10 rounds of firepower before a reload, depending on the magazine that I choose to use. I find that I can change magazines more instinctively than I can speedloaders, so I can focus more attention to the threat and my children. Additionally, I find that I can direct that firepower more effectively from my SA auto than a DA revolver.
I also understand that there is a damned good chance while trying to protect my children that I may catch rounds. I am comfortable shooting my semis either strong or weak hand ... shooting and reloading my revolver with weak hand only is a proposition that I don't want to experience.
Obviously, I don't want to experience a worst case scenario, but I have to prepare for it. Spontaneous mob uprisings and religious fanatics are happening too frequently, with little regard to the innocents they may encounter. In many respects, I wish that the threats still centered around the potential armed robbery or mugging.
