I have had conversations like this before with gun rights absolutists. My brother was all hot and bothered about some obscure Obama-era treaty with Germany that might have possibly raised the price of guns imported from Germany by a few bucks. He insisted this was an infringement on his Second Amendment rights.
Obviously, anything that is done to make guns more safe or make it harder for people to get guns who shouldn't have them will raise costs (whether in dollars or in time and trouble). Also obviously, any meaningful reform has to result in less guns in circulation. If the litmus test for conservative support for gun safety laws is whether a given measure "impedes gun ownership," then clearly there is no gun safety law that will pass muster.
