So I can currently looking at some 9mm Smith and Wesson (http://www.hellinahandbasket.net/archives/001565.html)
Now I understand a 9mm is a super sonic round with little stopping power. However, I will looking around a found that the recommended use of standard 9mm is target practice, where the 9mm Hollow Point is for Personal Protection.
Now does that mean the hollowpoints have more stopping power? All I know is that the Hollowpoints expand on impact. What does that do?
