Good link, I still say the .410 is a good defensive weapon, especially for those who do have the time or interest for practicing and learning adequate skills. But, that is just me...
Two years ago I saw a gang shooting where two guys were shooting at one other guy. They were about 30 feet away for most of the shooting and missed over and over. When they got about fifteen feet away, they hit the poor bastard (another gang guy) and wounded him. They continued firing and hit him with glazing wounds twice more. Now, I bet you these punks shoot guns more than the average good person does. I would bet you dollars to donuts that if a citizen had had a Judge Taurus with alternating shotgun and .45 shells joined the fray, they would have been much more likely to hit one of the punks and the psychological factor of being wounded would have stopped them or caused them to run away.
