Historical changes underway when it comes to packing heat in Missouri. Soon, you'll no longer need a permit for a concealed gun.

The bill, which becomes law in January, is 49 pages long. There are dozens of provisions, which makes it more confusing.

Here are two things to know:

1. Most people can carry without a permit.

2. You'll have more legal protections if you stand your ground.

This means you won't have to go through the training which is currently required for permit holders. You'll have more legal protections to use deadly force if you defend yourself in public or private places.

"Election years are always crazy in this industry and this is not going to be an exception in that regard," said Nick Newman with Cherokee Firearms.

Folks in the gun business say they're not surprised Missouri's Republican-led legislature used its super-majority to override the governor's veto.

"In the short run, it's good for our business because there will be a lot of people that wanted to carry a concealed, but didn't want to go through the permit application for whatever reason. So those people, we will see a slight up-tick in sales from those guys," said Newman.

However, he says in the long run, he fears fewer people will be trained on how to properly care for and handle a gun.

"I don't think anyone is having any wild west scenarios, but it does concern me and we use the analogy of driving a car. Nobody can just get in a car and drive around without having a license and having a little training and going through the permit process where you learn the ends and outs of what you can and can't do and how to follow the law correctly," he said.

"We are just going to assume everyone has a gun until we find out differently," said Springfield Police Chief, Paul Williams.

Williams, says he's disappointed with what many call a rushed vote.

"The most dangerous aspect of this is there are criminals out there who have not been convicted of a felony, failed a background check and the sheriff did not give them a concealed carry permit ... I guarantee you everyone of those folks is going to go out there and get a gun and carry it around now," said Williams.

You still cannot carry a gun anywhere. Government buildings, schools and hospitals are off limits.

Also, if you want to travel out of state -- depending on which state -- you might need your permit.

As we have reported in the past, several counties are dealing with a backlog of people trying to get their permits. Only time will tell if those waiting lists will shorten and revenues will decline.
