I just wear a t-shirt to conceal my Glock. Just like everyday for me. I very rarely see anyone else doing this! Do you serious guys think someone like me is a dork? To me IDPA is a fun way to apply some "pressure" to my live fire shooting. In a way to mimic real world situations to be prepared for a SD situation. I do enjoy the competition and strive to do my best but I never wear a vest when I leave the house! So do I cave in to the peer pressure or just be comfortable being the misfit? lol
