You are not concealing just because your firearm is facing a wall. The firearm needs to be intentionally covered by some article of clothing or other form of cover to be concealed (i.e. if you walked around with a newspaper held over your holster). If you carry a small auto in an IWB holster at 4 o'clock, only the people behind or to the right of you will be able to see the firearm, but it will be unseen from the other 270 degrees of view. That makes it unseen, but not "concealed". A big difference. If this weren't so, all of us OC'ers would be in jail for illegal concealment much of the time!
Oh, and welcome aboard! Plan on going to one of the dinners in NoVA or a VCDL meeting!
