I'm not sure what you are asking, but I'll try to answer regardless. There are 3 sources that might tell is what this means. Only two of them count though.
The first is the AG of the State of Missouri, Chris Koster. He can issue an opinion on it. He's basically said he doesn't know, so don't expect any help from him. That's OK, because his opinion only holds slightly more authority than anyone else's.
The second is the Missouri Legislature. They can look at the Amendment, and decide that some of our laws need to be adjusted to fall in line with it. If that happens, then it will not be before next year's session, because the Legislature is out of session, according to the Constitution, and may not meet for new business. Now, they might do something, but I doubt it.
The third source is the court system. This is most likely, but it will most likely require someone to OC where it is not legal without a CCW permit. Then it can wind through the courts. Luckily, there is a plan to do that, and pretty soon. Ideally, the changes require the state to defend the person picked up, but given the AG, I would not count that bird in the bush.
Overall, the Amendment is a grant statement of principles. it's not about particulars. That's not what the purpose is. Now that the state is agreed to these principles, it's up to the state government to handle the particulars.
It's not pretty, but it's how laws are done, and it's further than we've gotten in recent history. We'll have to see how it's played out.
So just what did we vote for? It seemed clear at the time, now I'm thinking our friends have fooled us. Why can't we get a straight answer on what it does? Playing games with words, perhaps. It either does or it doesn't. Maybe our friends aren't really our friends. I understand being coy before the election to reduce opposition but that time has passed. I'm on your side and still the games.
