With my SuperTuck, I have no problems carrying even a G23 with my shirt tucked in and it not printing. It's even easier with the subcompact G33.
There's no printing on the shirt, but what about the pants around the belt area? I can notice that it bulges a on one side and not the other. Do you think I notice because I'm looking? Do you think any one else does?
I can hide it a little when I balloon out the shirt, since it hides the contour of the belt.
