Not on your poll list, but the old .44-40 Colt Single Action Army Frontier Six Shooter is still just as capable of performing serious social work as it was 107 years ago when it left the factory.
Poll Fail.I don't regularly carry anything larger than 9mm so I have no dog in this fight. I do have a 44 Magnum but never carry it in town.
Since when are .38 Special and 9mm considered Big Bore?
Besides, everyone knows 9mm is the most popular carry round on Earth, so the results would be entirely predictable.
Yeah, if you're going to tote a .500 S&W you better eat your Wheaties...
