If any of you take the time to read the Goetz reference above, you might re-think the tactic of giving yourself up to the authorities after a self defense situation results in a shooting. Goetz was identified and so had no real choice but to surrender. If there was no likely way that your identify would be known, and if you fully realize that you would face felony gun charges just for having the gun in this situation, you might want to quietly go on your way. And in that type case, a revolver offers real advantage over a semi-auto unless you want to take the additional time to search for your shell casings. I wish to add that I am not advising anyone to break the law; I am just presenting a hypothetical situation where a revolver would offer a bit more "security" to the shooter than would a semi auto.
