Nothing wrong with having a holster to carry the pistol during the time you are dismounted. Someone's idea of a tanker holster (just slip in over your head) makes sense. Since Louisiana allows open carry, it is okay to have the gun visible (a deterrent) and readily available (quick reaction if needed) and secure (not in a pocket or belt). I also agree 100% about the responsibility to prevent theft of the gun from an unattended vehicle. A stolen gun will end up in the hands of a criminal in NOLA or go upriver to Chicago or something like that. In the broad expansion of CCW use in the past decade, which is wonderful and makes us all safer, not enough emphasis has been placed on training about when it is justified to shoot; how to secure a weapon in a car or house so it doesn't get stolen or into the hands of children; and how to prevent shooting something or someone by accident (the dreaded ND or AD, more prevalent with light, short triggers -- which seems to be what everyone wants in their striker-fired pistol). As a side note, rehearsing what you might have to do with this gun is a good idea too. Use your headlights to illuminate the places perpetrators might lurk. Break contact and drive away if you see a threat -- call the police. You are generally better off if you are in the car and it is running, so leave if threatened. If on foot, retreat if threatened -- run away if at all possible. Don't get caught chasing someone or shooting at them as they run away after seeing your gun (it will all be on the bank's video). The reason you are carrying a gun is to protect your life while doing something that attracts bad guys who would kill or injure you. You are not carrying a gun to protect a lousy few thousand dollars of cash, or to arrest or punish anyone intent on breaking the law. The Police have enough trouble with that. Be safe.
