There never has been that much control in Texas to begin with - registration is nominal, training non-existent and as long as you don't openly carry a weapon....
There was one incident while I was there, two cars engaged in some road rage on Westheimer in Houston. Come to a red light and one guy gets out. The other, in a Merc, leans over to his glove box, pulls out his gun and plugs the guy outside the car.
"I was only defending myself as he was starting to threaten me." Profession of the Merc driver - yes, a lawyer, and there was no court case.
The only ways that some control will be achieved is by limiting multiple-repeat weaponry (as per rapid fire/machine guns) and as I have always said, 'tax the bullets through the roof' and then give credits back to those who legitimately have rifles etc (gun clubs within, farmers etc - even the police - yes they have to buy their own munitions in Texas).
