3D printing technology has allowed us to print just about anything including a gun. In this article Youtuber Guy in a Garage built (printed) a Songbird 357 Magnum pistol that actually shoots a .357 cartridge. In the first test firing, the frame cracked at the top of the slide.
To repair the pistol, he glued the crack and added a couple of zip ties to keep it together. Yes, this is homemade, so would you shoot a homemade 3D printed .357 Magnum pistol?, enjoy the video.
