Defense Distributed of Texas announced on Sunday that researchers fired a bullet designed for a traditional .380-caliber firearm with a gun built all but exclusively using digital blueprints, some plastic and an $8,000 printer. The only item aside from the bullet not printed out was a single nail that served as the firing pin.

As early s Tuesday, though, California State Senator Leland Yee was already looking to pass a bill that would outlaw other 3D weapons from being built outside of the factories where firearms are regularly assembled.

Sen. Lee, a Democrat that represents a large chunk of California that includes parts of San Francisco, issued a press release this week condemning Defense Distributed’s inaugural 3D handgun.

“We must be proactive in seeking solutions to this new threat rather than wait for the inevitable tragedies this will make possible,” Yee said.
