What I take objection to is saying that, "You need to have X, or you're not prepared," where X is a type of gun or a number of rounds.
I think what it really comes down to is awareness, mindset, and proficiency. But that's a whole 'nother thing.
I would also suggest that you're not looking at the upsides of a revolver compared to a semiautomatic. For one thing, the manual of arms is a lot simpler. There's no slide to manipulate, and no safety to leave on. If you suffer a misfire, it's not the end of the world--just keep squeezing the trigger. It's hard--but not impossible--to jam up, and there's no magazine to damage or wear.
Is a semiautomatic faster to reload? Maybe. It still requires two working hands, and it's still easy to fumble. I would submit that it--and this is in no way a jab at pistol fellows--requires less skill and practice to reload effectively.
But even there, the humble J-frame has advantages. For the same bulk and weight of a semiautomatic pistol and two magazines, one can carry two pocket revolvers.
Not that I ever would. If I thought I seriously needed two revolvers to go someplace, I'd have to seriously reconsider going there! Which is a luxury I have, being responsible only to and for myself.
The other thing is--not all of us have access to high-capacity magazines. In my state, for instance, we're limited to 10 officially, and anything over 7 exists in a legal gray area. So there's really not much of a gap between a 7+1 and a 5 or a 6.
There is such a thing as fighting your way out of a bad situation.
Now, you may be in a place where there are no alternative exits, but I never much cared for a tactical poo sandwich like that.
