Maybe it changed, he was saying double tap the chest and single tap the head with the 9 and the 45 was a single tap to the head.

You guys on the forums always keep on this stuff, I don’t. That being said, I am sure there is a valid reason to have extended mags.

When I was in the service, we had 9 shot mags which were only loaded with 5 cartridges. In training we were told that the mags had a propensity for jamming when carrying cartridges for a long time in a full mag (they were only removed from the mag once per week for inspection). We were told that the spring when compressed for long periods of time would not reliably provide enough force to push a cartridge in.

Is this a reason for extended mags as well?

The chest area is larger and therefore an easier target to hit than the head. That said, two to the chest with a handgun regardless of caliber, with a follow up to the head if the first two shots did not stop the assailant.

As far as magazines go, newer metals used for springs in new magazines have alleviated some of the “fatigue” issues associated with keeping them loaded for long periods of time. However, if you don't have the time or $$$ to practice enough to make spring fatigue a non-issue, (the mag won't be loaded if you shoot all the bullets that are in it), you may be better served with a revolver.

With a wheel gun, you don't have to worry about spring fatigue as everything is at rest until you pull the trigger.

For magazine springs, it’s not constant compression that make them weaker. It’s actually using the springs over and over that causes wear.
