3D Printed Pistol v1.1: More Calibers

Image from Defense Distributed

The DEFCAD community has released an upgraded version of Defense Distributed Liberator 3D printed pistol.

As they are individuals on the Internet and not an organization, they have never received a letter from any government entity asking them not to distribute computer files.

Improvements include barrels for the .25 ACP cartridge and for the .45 ACP cartridge. No information was supplied to determine if any test firing of these cartridges has been done.

I suspect that the .25 ACP version would work, but I have doubts about the .45 ACP barrel. While the working pressures are similar to that of the .380 ACP cartridge used in the original version, the overall force exerted is much greater.

The new files include SLDPRT ( The SLDPRT file extension is associated with the SolidWorks application used to create 2D and 3D CAD designs); STEP (File Format Description: 3D model file formatted in STEP (Standard for the Exchange of Product Data), an ISO standard exchange format; and STL (STereoLithography) is a file format native to the stereolithography CAD software created by 3D Systems.
