The effective working definition of this became as long as it's covered, it's concealed. Short of showing some part or all of the handgun (and even then inadvertent displays didn't count), you would not have been bothered for any level of "printing" short of this, I think:
and maybe not then. Since the inception of concealed carry in Texas, the yearly total of license holders convicted of anything has hovered very closely to about 100 per year. I never heard of anyone convicted of failing to conceal. Or even arrested for it.
But having a bulge, a big "point" where the grip juts out, an L-shaped outline, not an issue.
"Printing" was never a problem in Texas, except on the gun forums.
