Oklahoma has the same kind of mickey mouse (pardon the pun) type of laws on the books concerning CCW on private property. In fact there is not even a state law defining a non-CCW sign specified in the SDA ( Self Defense Act) laws. I've have seen everything from the standard gun buster sign to fancy script stating "No Weapons Are Permitted". Some of them are in Spanish and since I do not read,speak or understand spanish that's too bad.

It is not a case of state law if the private property is posted, but if you are discovered all they can do is ask you to leave. If you leave then it is no harm no foul. If you refuse to leave then it is a trespassing charge.

If you are doing it right no one will ever know you are carrying. If I have to defend myself and / or my family, then I would rather be judged by 12 than carried by 6

The rule I go by if it's not covered by state or federal CCW laws then I "don't ask anyone's permission and I damn sure don't tell"
