Darned if I know! The virtue of the automatic is that the firing chamber is either perfectly aligned with the barrel, or at least the relationship doesn't vary. Revolvers have 5, 6, or more firing chambers, and while they are usually well indexed, they're less apt to be perfect. Either can, and usually is more inherently accurate than nearly all shooters.
Personally, I don't get too honked up on handgun accuracy. I take their prime use as defensive weapons, with 30 feet and under as being defensive distances. I have only known one handgun that was inadequately accurate at those distances. It was a double barreled derringer.
I have to agree
with your reasoning.
During target shooting, I tend to favor revolvers
for their superior mechanical reliability.
Automatics jam too much, even new out-of-the-box,
but after a few hours of target shooting with revolvers,
I must grudgingly
admit that I 've gotten marginally better accuracy from automatics.
I 'd be afraid to fire a Derringer; dangerous.
U coud get carpal tunnel syndrome from them, IMO.
Thay even come in .44 caliber; scary.
