The reason I'm not concerned by most of these stories is that when LEOs are involved it's an apples to oranges comparison to what most CCW holders will face.

A bad guy has a much stronger incentive to stay in the fight against the cop in order to avoid prison. By contrast, I'll consider it a win if either of us runs off.

I suppose there might be the rare individual who soaks up hits from my two revolvers and continues to attack. But even then I don't see where a single stack 9 would be likely to make a difference.
