The last time I remember the 3D gun subject coming up here, it was about a guy in Japan...and by Japanese law, he was basically screwed simply for making a gun.
This guy is in the US, so it's US law that's being tested this time. Here's his blog about the whole process:

Looks like the best printed pistol yet, makes me wanna design my own similar to that.
Putting chamber sleeves and barrel liners in these things can really make them into more functional firearms rather than 1 shot assassin pistols.
He stresses not to use PLA, but I've been doing some high temperature (240C) tests with PLA and I've found it's actually stronger and stiffer than ABS, and when printed hot enough it never de-laminates, not even under extreme pressures like thread forming parallel to the layers with a screw.
