What you don't know is that switching a magazine is nothing more than pushing a butting and inserting a new clip. If you are counting the rounds you shoot off, you don't even have to put a new round in the chamber. You just keep on firing.<quoted text>
Less than a second? doubtful, and especially unfettered. What is it that I don't know? The bushmaster?
If somebody is on a killing spree, they are not worried about catching the used clip. It simply drops to the ground. If you have a 10 round clip, once you get to your sixth shot, you continue firing with one hand while the other grabs the new clip. Push the button, snap in the new clip and keep on firing. You won't even hear a pause if you are listening to somebody switching clips that way.
If you visit your local gun shop and ask the salesman to demonstrate the speed at which you can insert a new clip, he or she will be happy to show you. Police practice this way during training. A 9mm semi-automatic handgun is one of the most popular guns the police use.
The point is, limiting the size of a magazine only makes the shooter do a little more work. It does not stop or slow down the damage he can do.
