I get it. But even if the mob was only 6-7, I'd think twice about engaging them with a gun that only holds 7 rounds. Unless I had a spare mag really handy. Of course if he shot the leader and 1 other, likely the rest would have scattered. Dunno, not sure what the situation was. If he had been drinking, which was likely - he would have been in seriously deep kimchee if he had popped someone - even if it was justified. Maybe he thought hard about how much he was willing to risk to save his buddy from a beating that he may have brought on himself anyway.
On a side note, it kinda dispels jocal's notion that all CCW holders are vigilantes out to dispense street justice and engage in unfettered "gunplay".
So you wouldn't use your weapon to defend yourself unless you had sufficient ammo to kill all of them?
