I just couldn't do it. I tried. I am "portly" (fat...190 lbs. 5'8"). I tried a size up on my pants, but that wasn't the answer. I went to a belt holster and that works. I adjusted my style of dress. Summer, it is Hawaiian shirts, or oversized T shirts. Winter it is a Tee shirt with a 5.11 shirt untucked over, or when it is cool enough a vest or jacket over. I believe that "printing" is not an issue in Texas. The law doesn't prescribe any punishment, and the criterion for detection is very vague. I just put the thing in a holster, cover it with something, and don't worry about it.
I carry daily, but no one has ever noticed it, or if they did, they have never said anything.
I firmly believe that if you are not aware of it, no one else will be either.
