I realize coming in this late that most of these have probably been discussed already, but here goes...
1 Out of the box they are considerably more accurate than most autoloaders, and more forgiving of load.
With the exception of my pocket pistol, I've had no issues with the accuracy of my autos. You actually have a longer sight radius with the same length pistol in an auto, and for me the revolver and auto have been about the same overall accuracy.
2 They will shoot heavy loads, and light loads without ever having to worry about which recoil spring is installed. Will it function the action? Not to worry, if there's powder and a primer, she'll go bang.
True. But if you only have a gun for a specific load (i.e. my handgun is designed for HD/SD, and practicing for HD/SD), then you know the gun can handle it.
3 No FTF's, FTE's, Stovepipes, etc.
Maybe not those failures, but I've seen a revolver fail to fire and I've seen the cylinder lock up more often than my autos have failed.
4 Not too many autoloaders that can go toe to toe with the revolver on power.
Not too many revolvers that can go toe to toe with an auto on speed while maintaining the power advantage.
5 You know when it's loaded.
Actually it's easier to tell if my XD is loaded than if my revolver is loaded, especially in the dark.
6 The revolver is ideal to introduce the new shooter, clearing, loading, and shooting are so much less complicated.
Everyone I know that I've started I started on an auto, and they seemed to pick it up just fine. Actually with a lot of shooters today, autoloaders make more sense than revolvers, because they're more used to seeing them in movies/video games and know at least the basics of how they operate.
7 You can easily see that it's loaded.
See number 5.
8 If you reload, your brass is really really easy to find.
True.
9 "Glock Leg" much less likely to happen
It is likely to happen on an auto?
10 And you gotta just love watching the cylinder turn.
Not really. I like watching the slide slam back.
