I don't hunt or carry it for SD but the .357 is my favorite round to shoot. We can still have fun with our guns, right?
Absolutely. having fun is just as important as being useful. If you WANT a .357, then the question's moot, isn't it? buy what you want, or buy what you need, and make sure your purchase fits your wants and needs.
I very rarely shoot .357. I just like my .38 pistols better. Even at that, I have .38 +P in my .357 for my nightstand gun. I'd prefer not to use full house .357 loads, but in another neighborhood, that wouldn't be a concern.
I've told this story several times here, and even been accused of making it up. My father was charged and knocked down by a grizzly when in yellowstone. A park ranger went to look at the bear, since it was near a camping area, and killed it with a .357 when it charged him.
That's what it can do, and that's a good reason to pass on the .38. times when you just got to have that extra power, if they ever happen.
If that guy had really believed that it was a grizzly on that sandbar, and thought that it would also attack him, I don't think he would have gone looking for it with something so bloody small. Carrying a .357 as a "just in case" weapon and actually going out looking for trouble with one are two different things. same thing really goes for .38 special and .380, I guess.
