Although The advantages of modern semi-autos are many and revolvers hold no advantages that I see, other than hunting applications.
With all due respect, I beg to differ. Here are a few advantages that immediately come to mind:
1. Immensely different power levels and loads can be handled with aplomb in a revolver - not so in a semiauto.
2. The revolver does not fling empties into the air. While this is a convenience, it can also work out to being a tactical advantage - no trail of cases during or following a justifiable shooting.
3. Reliability is not as much of an issue as it used to be when considering revolvers vs. semiautos, but still, I have 99.9999% confidence that when I pull the trigger on a revolver, it will go "bang." Even more important, successive shots will also go "bang," unless you have a dud round, in which case, the drill is to simply pull the trigger again. Clearing a dud or a jam with a semiauto is a bit more involved and time-consuming.
4. Considering pin-point accuracy at longer range, the revolver will have a slight edge. With most semiautos, the sights and the barrel have a tenuous relationship - in short, there will usually be some slop in the system between the two.
5. Is it loaded and ready to fire? With a revolver, just look. With a semiauto, looking usually involves a press-check, or the added complexity of a loaded-chamber indicator. Even with a notch in the barrel hood, you might need a strong light and a magnifying glass.
6. The intimidation factor. The person on the other side, when confronted with a revolver, will see immediately that he is facing a loaded firearm - no doubt about it.
7. Condition of readiness is simple. Once loaded - all you have to do is pull the trigger. No worrying about manual safeties, magazine disconnect mechanisms, loose magazines, or not being fully in battery.
8. Don't worry about leaving the gun fully loaded for long periods of time. There will be no compressed springs to lose their power over time. It will be as ready to go 20 years from now as today.
9. With a semiauto, a dropped magazine will result in a 1-shot wonder, or a poor substitute for a hammer. No sweat with a revolver - it doesn't HAVE a magazine.
10. With some revolvers, they can be fired multiple times while still in a jacket pocket - the Centennials and shrouded hammer models most certainly. After the first shot with a semiauto, I can almost certainly guarantee a jam, precluding any further immediate use.
Your honor, I rest my case.
