I like the fact that revolvers require less testing.
If I get a new autoloader, I feel that I must test my carry ammo with X amount of rounds. I feel that I must test my carry ammo in each magazine to test each magazine function.
With a revolver, I put a cylinder full of ammo, test to find the point of impact, and if it's acceptable, I'll carry it. Simple.
I like the way that revolvers simply melt into your side when carried IWB, as opposed to a similarly sized autoloader.
I feel when shooting an autoloader that the slide racking under recoil is obnoxious. A revolver's recoil is quick and simple.
I prefer the double action pull of the revolver trigger to the striker fired mush trigger.
Yes I like single action 1911 triggers, but I prefer no external safeties.
I dislike typical SA/DA triggers, like SIG or Beretta. Their single action triggers, while nice in theory, have such outrageous take-up.
I don't like picking up my brass.
I like that I can make the revolver safe by simply opening the cylinder.
I prefer not to worry about bullet set-back from re-chambering the same round. I just don't want to think about it. Load and unload as needed, and don't worry about anything.
And finally, I actually like the sight picture of a fixed sight revolver.
There are more reasons, but these are what I can think of now.
