Well, a fine kettle o' fish we find ourselves in, yet again. Thread started by a member who asked about the viability of carrying a revolver rather than a semi-auto, presumably due to arthritis that he mentioned. Of course, he's since vanished and hasn't yet acknowledged the plethora of informative, logical, evidence-based and witty (you're welcome) posts in response to his questions. As always, every poster in the thread remained laser-focused on the thread-starter topic... uh, wait, never mind.
Somewhat predictably, the thread has degenerated into the usual discussion of how many rounds is enough for one's self-defense handgun, which platform (semi-auto vs. revolver) is really best for lethal force encounters, and the usual caliber superiority debate (9mm vs. .357 vs. .45 ACP).
Don't know about the OP, but I've opened another bag of cheese popcorn...
