As for how much ammo we carry. We pretty much all have our preferences. Some based on experience, some based on lack of it and some based on preconceived notions or nothing at all other than habit. Hans is a very pragmatic guy and he is statistically likely to be correct when it matters.
My personal idiosyncrasies tell me that when I am carrying a .45 ACP, 8 and a spare mag or two will do. When I am carrying a 9mm I see no reason to carry a 9mm that has less than a 17 round mag. And a spare mag or two. I am not particularly pragmatic when it comes to this particular topic. I generally carry as much as I can carry and conceal comfortably.
