The only drawback I can see is if you do need the second gun in a situation, or even HAVING a second gun, can make a sticky situation if you end up in court. A lawyer could play the jury to believe that you were looking for trouble because of your "excessive" firepower. I bring this up because a former county attorney brought it up when I had my .357 on the belt and a .380 PPK in my pocket. He and I are both permitted, and were discussing it one evening. He named a few lawyers here that would make me out to be the bad guy in a situation. However, whatever I'm carrying at the moment, don't doubt I have at least one reload on me.
