I asked my rowdy neighbor this question.
He said no change except that if driving and seeing a situation he doesn’t like, he puts his S&W 642 under his left thigh. Says folks outside the truck can’t see it and he can Quickly get his hand on it without drawing any attention.
I think one or two of the FBI agents involved in the '86 Miami shootout did the same thing.
When their cars came to a sudden stop their guns ended up on the floor. They started the shootout looking for their guns on the floor rather than drawing from the holster and firing.
