If you are wearing shorts and a tee shirt you are unlikely, despite the protests on here, to carry a 1911 or a Glock 19 or 17 or even a 26. My BodyGuard 380 is ALWAYS with me whenever I cannot carry my M&P9 or Glock 19. Any comparison to a 380 being a "girly" round makes me want to see you have one ponted at you. Let's see if it scares you or not. After you are shot I bet you will not be joking around anymore.
I carry a full size Glock 17, wearing shorts and a t-shirt. I have been for the last month or so....
