Any fun-loving firearm fanatic's out there living in Montana? Being from tight-*** Canada, where they outlaw EVERYTHING you can possibly think of, I need some answeres from someone there that know's the laws.

at the end of this week, I will be down in the US for 10 days. What are the chances of while there, getting a hold of a firearm? Can this be done? What is required there to purchase a handgun? I have all my Canadian License's ect, but what's the deal there, and what is required to purchase one?
