They used to be called "zip guns" or "Saturday night specials": Cheap, sometimes home-made firearms with mostly coincidental accuracy (You hit what you were aiming at? Pure coincidence!) and a penchant for exploding in the user's hand.

They're to mass-produced firearms what cheap bathtub hooch is to Jim Beam.

Wikipedia mentions them along with much more sophisticated designs:

I once watched a Vice documentary about Afghanistan, name escapes me at the moment, and they showed this blind guy making a replica of a Russian Makarov handgun by hand, with very basic tools. We used to manufacture revolvers before 3D printers, the industrial age, modern welding techniques, or pretty much most of the technology we enjoy today. The truth is, you can make a perfectly untraceable, very reliable, simple gun with out 3D printers.

... if you invest a lot in the proper materials, tooling, and skill set.

Takes way, way less time and energy to learn how to use a mill than to try and print a single-shot ABS weapon on most hobby-grade 3D printers.

Not to mention, the results you'd see from a mill are much safer, reliable, effective, etc.
