Although there’s a fellow or two out there with plans that (they say) could be used to control milling machines to duplicate Real Guns (TM), everyone’s focused right now on the so-called “Liberator,” a printable resin gun that, like its WW2 namesake airdropped to the French Resistance, holds and fires one shot at a time and shoots marginally better than no gun at all. Me, I think the early adopters are going to have more problems than the gun is worth.

Agreed. The 3D guns are the biggest nothing since disco. Anyone with a decent metal mill can make a pretty good revolver. After all, Colt made hundreds of thousands of very good pistols with 19th century machining tools and water power. High capacity magazines can be made in any sheet metal shop or by a hobbyist with sheet metal tools. My brother and me made our first black powder rifles in dad’s home shop when we were 11 and 15, respectively. By the time I was 16 and he 12, we had made our first percussion cap black powder revolver – then we found out dong so was somehow illegal so we stopped. You can make a shotgun with two pieces of pipe and a nail – the Philippine resistance did it during WWII.
Or just buy one off the black market for less money than you’ll likely make in your first robbery.
If people think criminals are all dumb and cannot machine pistol parts, remember, criminals thought up a way to turn a chemical laboratory into meth making devices contained by a 2 liter soda bottle. That’s criminal genius.
