So, if we can refrain from cliches and armchair-urban-soldier fantasies, I'd like to hear who else might carry like this, as well as well-reasoned arguments for why I shouldn't.
How about advice from a retired cop? An empty chamber in a carry gun? You may as well carry an empty gun. If you really, really need it, in about 1/2 to 3/4 of the incidents I worked or was around you would never get your gun into play. You must think about how am I as the predator going to take you that maximizes my success potential? If I was going to take you, I would attempt to overwhelm you physically.
This has come up time after time. Take a FOF class and try get your gun out and chamber a round while fending off an attack.
