John H, don't listen to all these nuckelheads, there are situations where you may need more firepower from your handgun. For instance, look at what happened in Waco, all the officers surrounded the house and then started to 'spray and pray' before they went in (I'm not saying that what happened in Waco was the right way to do it).
Waco
In combat it's called 'COVER FIRE'. All these city folks with civilian CCW training and that have never been in combat (except in their local McDonalds) have no idea what combat is like. In your house you would use your 1911 to fight your way to the gun safe so you could grab your AR-15 with 100 round drum (or equivalent). If you had to move through a clearing with several people firing at you, you would have to run while at the same time shooting, not taking precise aim at each guy, but rather shooting in the general direction. What that does is stop them from shooting and gets them to find cover for the few seconds you are running to your gun safe.
Urban combat is not like rural combat at all, you don't have to worry about rounds overpenetrating or hitting civillans, even more so in a wooded part of the country where all your rounds will hit trees in a hundred yards or so.
There are a million tactical situations and just because we've never been in one doesn't mean it won't happen. The new big threat that the police are training for is terrist attacks with guns here on American soil, all starting to shoot at the same time. I can see this threat being real in a few years after the government bans most of our weapons, then we may need tactics like this to survive. It will be just you and your seven round handgun trying to defend fellow citizens from a mob of terrorists.
I agree aiming and taking out one bad guy after another while they stand still and take it is the ideal situation, but it rarely happens like that. Just ask the guys in Vietnam how many of them sprayed and prayed vs. only shooting nice and calmly when they saw a bad guy.
Also keep in mind the Armed forces is looking for a new handgun, one besides the ineffective 9mm. They are thinking of going back to the 45 ACP or at the very minimum the .40, and their requirements is that the guns must have a MINIMUM of 10 round capacity. That eliminates most of the 1911s out there on the market chambered in 45 ACP.
Spray and Pray: It's called COVER FIRE, and we are talking rural combat againt a bunch of combatants, not McDonald'S civilian warfare! Don't worry, most city people can't even comprehend life in the country.
