This is a really good discussion/interview Colion Noir has with a guy that pulled his firearm and shot a guy - or two and he does a good job of basically letting the guy describe what happened, not interrupting. Although it references a round in the chamber, it's not a discussion on what should/should not be done, just a good listen to what he went through and experienced, good info for possible future use.
