There’s a huge difference between a 3D printable FRAME and a 3D printable GUN (which is all parts).

The all printed pistols even need secondary machining to work at all.

So, no, not one of of four but four out of four.

Legally, the frame is the gun. All the other parts needed, including the barrels, triggers, sears, springs, firing pins, etc., are just parts that can be purchased legally in this country anywhere by anyone with no govt involvement - which is the scary part to the author.
