People who carry concealed tend to look for telltale signs of a concealed weapon on everyone else that they see pass them by.
Just the other day I noticed a man in his 30's walking out from the Target store and noticed his gun printing in his right front pocket. If I had to take a guess, I would say it probably was a Kahr PM9 or a similar sized pistol.
No big deal, and no one else seemed to notice either his pistol or the J frame S&W .32 magnum in my right front pocket.
As long as you are legally carrying, I wouldn't give it a second thought.
