I should add, multiple assailants with higher cap weapons. The revolver, as cool and effective it may be, is not the adequate tool for the times we're living in.
If those multiple assailants have lost one or two of their
buddies, they of course will not lose morale but
redouble their efforts to attack and the outcome will
be the same whether you had a 6-shot revolver or
a 17-shot auto.
Now, if you reached hard cover protection, no doubt
the assailants would calculate that your revolver is
about to go dry or has already and they will risk
themselves.
Of course, perhaps my scenarios are a bit silly but
so are the ideas that a hi-cap firearm will scare away
or subdue multiple assailants, especially if they have
surprised you.
And on and on the possibilities. It's what "gun schools"
and gun magazines and some manufacturers
love to preach for continued sales.
Now, if you prefer an auto and are better with it than
a wheelgun, that's fine. Even if you'r not but feel
more comfortable with lots of ammo, fine.
But don't discount the folks who prefer revolvers.
By the way, what police and the military think is
necessary doesn't translate to the needs of the
"civilian" Ordinary Joe/Jane going about their
daily business.
