Here's why I don't carry revolvers anymore:
1. More bullets is always better than less. If you don't need them all, so be it, you can't know that ahead of time, more is still better than less.
2. Since I am not Jerry Miculek, I can reload a semi much much faster and smoother than a revolver, with less fine motor skill, even more so with only one hand.
3. After shooting bunches of ammo thru many examples of revolvers and modern semis, I have seen nothing to make me believe revolvers are more reliable than semis, perhaps have seen the opposite, and when a revolver gags, it's a lot harder to clear.
YMMV
