That's not exactly correct. Colorado law does not necessarily "end" at the border. The scope of jurisdiction of a state's laws is far far more complex than that. But its irrelevant to the question of the thread, which is whether or not a Colorado resident can transfer those magazines to an out of state resident (note that an FFL can), and by a strict reading of the text, the answer is no, a Colorado resident may not. And Colorado can certainly regulate the conduct of its residents, especially within the borders of Colorado.
So you really really think that the almighty chickenlooper and company have any enforcement outside of the border? I think not. There's not a single entity from this state that can enforce this garbage outside of state lines.
