WATCH: Red state gov urges firearms makers to ditch Colorado amid its anti-gun push

Gianforte has helped spearhead greater protections for gun owners and sellers in his state, including through making Montana a constitutional carry state and through the passage of a law that prohibits law enforcement from enforcing federal firearm bans or regulations that infringe on Americans' Second Amendment rights to possess, transfer or use any firearm, magazine or firearm accessory. 

"My message to them was pretty simple," he said. "'See what's going on in Colorado? Do you want to move back to America? Because Montana is open for business, and we would welcome you here.'"

"We have more firearms and ammunition manufacturers today than any other state in the country per capita," touted Gianforte. "We proudly defend the Second Amendment, not just for our firearms owners, but also for firearms manufacturers and ammunition manufacturers."
