It might for states like Massachusetts. I follow firearm legal developments, but I don't remember specific restrictions by state.
I can say that this will make zero difference for Calicucks because they have a state run roster of """certified safe for sale""" pistols. If your pistol is not on the list then it's illegal to sell it to civilians (cops OK) in the state. Oh, you wanted to know how to get on the cali roster? "Fuck you", that's how!

BTW, the "cop loophole" creates a grey market where you can technically buy any pistol you want as long as you find a cop buyer and pay him 3-5x the sale price (because cops are limited on how many of these "off roster" firearms they can purchase per year themselves).
