OK, it's a little old, but I didn't want to start a new thread on the subject.
When I sit down in the restroom , I rebutton my pants around my knees. That keeps my gun in its holster, up off the floor, and out of the view/reach of anyone outside the stall.
I'm also looking into using a belly band. (See also:
