If revolvers were easier to hit with and more reliable than auto's the military would have kept the M1917.
Autos/semi autos in the military are/were are about regular troops putting lots of bullets in the air against multiple adversaries during combat. Shooting one or two bad guys in civilian life is a somewhat (but not entirely) different scenario. Their are advantages and disadvantages to both. For the average person who goes through daily life and then unexpectedly and suddenly finds the need to use a firearm, a revolver is most likely simpler to use under stress.
