Man, oh man. The time of year and dress really changes this one. The most carried throughout the entire year is probably the .380 due to ease of concealment. Open carry, for me, is when the wind blows my shirt up or I bend over.
Closely followed by .38 and 9mm.
I don't even want to imagine what that holster looks like or do you go commando
