I am new to OC and am waiting on my CC. I am aware of almost all gun laws especially when it comes to CC. I am aware in some locations that you are not allowed to OC a loaded gun, magazine and cartridges must not be in the gun, while others locations do allow loaded OC. I do not know where Montana stands on this issue, the law does not (to the best of my knowledge) state anything about a loaded OC, which means that it is legal, but I may have missed something. Thanks for your replies!
