Firearms makers are pulling up stakes in at least two of the five states that enacted gun laws after the Newtown school shootings, Colorado and Connecticut, NPR reports. New York, Connecticut, and Maryland enacted broad new bans on assault weapons. Delaware passed a law requiring universal background checks. Colorado adopted background checks and a ban on high-capacity magazines. “To have this many states have so many changes in one year is absolutely unprecedented,” says Robyn Thomas of the Law Center to Prevent Gun Violence. She says gun control advocates are targeting states they weren’t even thinking about before, like Washington, Oregon, Virginia, and Nevada. In Colorado, firearms maker Magpul Industries said it’s leaving the state in response to the high-capacity magazine ban. Gun maker Beretta threatened to leave Maryland, but will stay put and add jobs only in other states. In Connecticut, at least one rifle maker is planning to move because of the assault weapon ban.
