You see the same thing at pistol matches. People forgetting to release the safety, having to pause and look for the mag release, all sorts of problems.
Then there is the revolver. Nothing to do but pull the trigger. Nothing to thing about (I don't let students use the hammer on a DA/SA revolver). Just pull the trigger, no thinking, no fumbling. Sure the is the cylinder catch, but they're suppose to be behind cover for reloading.
I know there are those who will pick up their gun, without thinking get it in action, reaching the safety, mag release, slide release without ever changing their grips. That is the exception.
I have to disagree a bit about the fumbling issue...
Take an unloaded revolver with a loaded speedloader, and an unloaded autoloader with a loaded magazine:
Revolver: (1)release the cylinder, (2) insert the bullets in the cylinder using the speedloader, (3) close the cylinder, and you're ready to go.
Autoloader: (1)insert loaded magazine, (2) chamber a round by racking the slide, and you're good to go.
A there are plenty of Glock style pistols that don't have a manual safety, so there's no fumbling there.
Seems to me that both are very simple and easy to use.
Which is why pistols and revolvers are used effectively by teenage and children warriors around the world.
The differences in my opinion:
Most folks will be able to reload much more quickly with an autoloader (if they have another loaded magazine).
Autoloaders can take more physical abuse than the revolver.
You can drop a Glock off a 30' cliff and it will probably still fire with the first trigger pull.
Revolvers can take more neglect of maintenance than the autoloader.
You can put a revolver in a cabinet and leave it there for 200 years and it will probably still fire with the first trigger pull.
You can customize the grip of a revolver much more so than with an autoloader.
It takes me longer to clean a revolver than an autoloader.
I can completely detail strip my autoloaders much quicker than I can detail strip my revolvers.
