In my mind, simply being armed with an effective handgun is much more important than ammo capacity. Most dirtbags don't plan on armed resistance. I'm referring to a concealed handgun. Surprise multiplies your effectiveness and gives you a better chance of escape, survival. IMHO, the J frames (and similar)are the smallest, easiest to carry weapons that remain truly effective. I wouldn't ever choose a J frame if I was planning a gunfight, but if you live to limit your risk, the J frames are a good choice.
