A lot of that has to do with mindset and how you shoot. I have several high capacity firearms and seldom do a magazine dump, even when shooting my 22. I have never been in a defensive situation and pray I never get in one, but when I am shooting, even just plinking, I take the time to pick my target between shots. Even when shooting dirt clods on the backstop I still pick my targets. I imagine this would carry over to defensive shooting. If you are like some people who like to just empty a magazine it might turn into pray and spray. I have shot IDPA, IPSC, and Bianchi although it has been a while and this will teach you to pick your target. I would feel comfortable with a single or double action revolver or semi auto but I still prefer a semi auto for capacity.
