Here in Colorado, when you purchase a firearm from a *** shop, whether it be a ******, rifle, or shotgun your driver's license info is sent via computer to the CBI (Colorado Bureau of Investigation) and depending on how busy it is, usually, within 30 minutes the buyer is approved or refused. If your record shows you were in a mental hospital or, if you have been arrested for spousal *****, ***** *****, ******* **** use, or any other crime, you will be denied.
If you buy a firearm from an online *** store, they will only send the *** to a verified *** shop and in order to be able to pick it up after paying for it, again you will have to send your information to the CBI for approval, just like the above example.
Colorado also allows for open carry. However, if you enter a place of business you can be asked to leave.
Colorado also allows concealed carry. A person wanting to legally carry concealed is required to take a class on firearms and safety, to know the laws, take a written test, and then if you pass the written test you are taken to a *** range and required to shoot six or seven rounds at a target the distance of 15 feet, and then six or seven rounds at a distance of 25 feet. Each distance repeated twice. If you don't hit the silhouette you don't pass. Also, if you demonstrate careless handling of your firearm and don't pay attention to the Range Master's commands, you will be told to leave.
The class typically costs anywhere from $65 to $90.
