The real issue is the half-round barrel profile and reusing the slide. I have some ideas on that, but it's not as straight forward as some other 3D printed pistol frames. The Raven uses a flat bottom barrel to remove the need for a recoil spring guide, etc, and that profile is unfortunately translated to the slide front. If you use a round barrel profile then you need to reengineer the front end of the pistol to keep the recoil spring from kinking, binding, etc.I'm impressed. The Raven is a perfect candidate for 3D printing IMO.
Yeah, I was wondering how you would handle that. I don't think the 3D printed barrel -drilled out for a barrel- could take the stress. When Cobra made the Denali, the barrel was configured much like a Hi-Point barrel with it set into a block of Zamak. Cobra realized a polymer frame couldn't hold the pressure of a barrel pressed into the frame.The real issue is the half-round barrel profile and reusing the slide.
