There are no criminal penalties it simply states that you may be removed from the premises. Many people say that something listed in 1-17 are off limits, but the result of carrying there is the result of carrying anywhere: If the people in charge ask you to leave, you must. Missouri effectively has no criminally enforced off-limits locations with the exception of buses which are covered in a separate law and CCW is not an exemption. However, I do know a couple of Troopers who said they enjoy the duty.

Casino duty for the State Troopers among the rank and file is usually considered to be punishment duty when they are assigned to the boats.

It is my understanding that just like the other signage laws, the most they can do is ask you to leave if you are caught with a concealed weapon. I've only been to the casinos a handful of times and that is just what I remember way back when the casino laws were drafted. However, take all that for what it's worth. It is also my understanding, that according to the letter of the law, they must maintain a crew capable of operating it as a vessel, including a Captain. However, technically speaking, in accordance with the law, the must maintain the technical capability to move freely detached from the pier, and have a working engine. The casino's are semi-permanent structures which are essentially never intended to go up and down the river.
