Shinzo Abe, the former Prime Minister of Japan, was assassinated with a gun on the streets of Nara, Japan. The killing shocked the world and, especially, Japan—a country with strict gun laws and tight control over ammunition. It appears that the killer used a homemade gun to carry out the attack. 

Officials in Japan, journalists, and firearms experts have all called the gun used to kill Abe "homemade." Typically this refers to a 3D printed weapon, but the weapon used to kill the former Prime Minister appears more crude than that.

Abe was in the streets delivering speeches as part of a political rally when the killer approached so there were a lot of cameras in the area. We have a clear view of the killing, its aftermath, and the weapon used. In video of the attack, two loud bangs ring out followed by large plumes of white smoke. The attacker was immediately wrestled to the ground.
