I'm going to concealed-carry a Colt Defender 45. Today, I went to the gun show in Fort Worth and ended up buying a waist band holster. Under my t-shirt, you can tell something's there. You just can't tell what. I also have a Colt Mustang 380 (much smaller frame) and it looked the same. I didn't particularly want to carry an in-pants holster in the small of my back cause my shirt might ride up when I bend over. What kinds of concealed carry holsters are y'all using?
