It's true...there is a fundamental understanding and desire we all have when it comes to cramming our sticks in holes. Never underestimate the primal aspects of shooting!
Seriously, though...it is easier, and you generally do not need to do it as frequently with an auto as with a revolver. So you are faced with this question:
In the event that my life has suddenly begun to suck so hard that I just had to empty a gun at someone/something just to keep on living for a few more minutes, and I'm not even done this stage and need to keep shooting at stuff or I think I will probably die, would I rather
a) attempt a reload which is a bit easier, less frequently
b) attempt a reload which is a bit harder, more frequently
It can definitely be argued that 5 or 6 or 7 or 8 shots will probably be enough.
But it can also be argued that calling 911 will probably be enough. In fact if you run the numbers, I would guess "never worrying about being attacked" is probably enough for the overwhelming majority of people.
But if I'm that one guy with the winning Lotto Max of Suck ticket shooting at people, personally I want every conceivable advantage.
