Personally, I think to much is made of the capacity thing. I think we often get to focused on higher capacity handguns for these kinds of situations because it gives us a bit more of a warm fuzzy feeling knowing you have 15+1 but in all likelihood, for most shooters, it's a false sense of security and we should be far more focused on selecting something we can draw and easily shoot well in a variety of circumstances. Focusing more on something that is comfortable for you to shoot then shooting it often and getting very proficient with it, IMO, is far more important then the number of rounds it holds.
