My message is/was: I have practiced extensively, under stress, with a variety of speedloaders. The only ones I don't regularly fumble are moonclips, which are too fragile for daily carry, at least for me. So I don't think there is any practical way for me to reload a revolver under combat conditions. The good news is that it appears to me that I am extraordinarily unlikely to ever have to reload under combat conditions, so I have decided not to worry about it.
Now, that all applies to me and not necessarily to anyone else. I wrote it just as one more data point for folks who are going through a decision-making process and I hope it is helpful.
