I suppose it is mostly out of convenience. It is mostly because you happen to have a 5-shot revolver that you like, so you are convinced that it is enough. But I wonder what the choice would be if there were no tradeoff for ammunition quantity in terms of the size or weight of the weapon.
Just curious...
I'll bite.
For me, I set round count pretty far down on the list in my priorities when looking for a defensive firearm. Many other factors carry greater weight (ie, fit to hand, pointability, ease of carrying, control layout, trigger quality, etc). If two choices rate equally high, except for round count, then I'd choose the gun that has the higher capacity. But such is not often the case for me.
It is within reason that a number of BGs greater than one is going to be present, and in that case 5 rounds is not enough.
Not necessarily. When the bullets start flying, the average badguy probably doesn't want to get shot either.
That leaves one or two rounds to take out three armed perps, who most likely will be packing hi-cap semi-autos, so it's reasonable to assume they'll have at least 40 or so rounds between them.
Common sense tells me that those aren't the kind of odds I'm going to bet my life and the lives of my loved ones on. I'll use a 5-round snubbie for a backup, but I'm darn sure going to have a fully loaded hi-cap semi-auto ready at all times as my primary.
With those kind of odds, I doubt what handgun you have on you is going to matter much. Just make sure its something you can shoot well. I generally perform better with revolvers and 1911s, so that's what I stick to. Long, drawn out gun fights are a rare in civilian self defense. So I carry what I can draw very quickly and is a natural pointer in my hands.
I'm not willing to bet my life and the lives of my loved ones on a minimalist approach based on simplistic averages.
the typical LEO shooting confrontation occurs at about a distance of ten feet, and the LEO's involved will MISS with about 70 to 80% of their shots.
70 to 80% is also an average. Some people (LEOs and armed citizens alike) perform much better, others much worse. So in that regard, I won't handicap myself with a gun that holds a bazillion rounds of ammo that I can't shoot well. Doing so means that in order to come out alive, I must rely on throwing enough led downrange that hopefully, a perp will sooner or later walk into a piece of it
. I have yet to shoot a double stack, hi cap auto
consistently as well as a J Frame or 1911.
Note that I don't knock hicaps whatsoever. As a gun nut, I'd love to own one of everything
! But when it comes down to protecting myself, I simply fall back on what works best for me.
