Shooter
OP: You are talking about two different things. A "gun fight" means both parties are armed and firing shots. This is not really related to the statistical average of how many shots it takes to stop a random attacker. If you are ever in a gun fight, especially one where you have to take cover, lay down suppressing fire just to be able to move, or there are multiple armed attackers, you would surely prefer higher capacity.
