So at least on paper, these two cartridges are awful close to one another when considering launching similar weighted bullets at similar velocities. Fundamentals of auto vs. revolver non-withstanding (capacity, perceived reliability issues, flexibility etc.): is this stubby .40 as good as our first magnum? This question comes up as I have been trying to provide information to a friend who is going to buy a first handgun. Initially he was looking at a .357 revolver (a 3" S&W 60) and he said it just felt very natural and comfortable to point. He is shorter and stocky and his mitts fit the smaller grip better than the larger framed guns, and prefers the lighter carry weight. Unfortunately after he had a discussion with a guy at ther gunshop, he is feeling that a 5 shot .357 is woefully inadequate for self defense and trail use; now he is undecided. I don't really have much of an argument as I have only a 3/4 of a box of experience with the auto round, and in my perception the .357 is far more powerful and flexible - it's just that paper seems to diminish that claim. Given the hypothetical bear attack situation (I find it irrelevant but it always seems to come down to that) will 5 shots of magnums suffice?
