Yeah you will always here the stories, "but a five-seven can penetrate bullet proof vests!" Just learn to nod politely and ignore it. It's the rounds inside that make it more or less, for lack of a better word, deadly. People also talk about the amount of rounds it can hold, and that's cool n all, but if you can't put them in the target accurately, or not at all because they feed like crap, it really doesn't help you much. It's becoming more novelty than anything, like the desert eagle. Meant for glass shelfs and video games.
