Quote - there's actually a model out on the interwebs somewhere to print the lower receiver for a 9mm.  That's the only part of the gun that you legally have to have a permit to own.  With current legislation, there's no prohibition on or license to own a 3D printed gun.  Allegedly (and i couldn't find the youtube test-firing of it) it's a pretty decent one-shot gun.

I was going to mention I'd read that article as well, and you wouldn't catch me with a 3D-printed anything for a firearm (outside of control surfaces) just for durability reasons, let alone the legality issue of creating your own receiver. Me thinks the BATFE would pay you a visit shortly after... 

Anyway, there's a reason why Glock and their ilk uses metal-reinforcement and ABS injection for their frames (mainly that whole saddling recoil issue). 

OT, but you ever see a super slo-mo of a Glock being fired? I sold my G20 afterwards, though slightly unrelated. My 10mm is all steel now 

Add: More OT, but my web hosting service finally fixed their server; free book uploaded today.
