Gun used to Assassinate Former Japanese PM Shinzo Abe

The improvised zip gun built and used by 41 year old army veteran Tetsuya Yamagami to assassinate former the former Japanese Prime Minister appears to be muzzle-loaded and electronically initiated. It appears to consist of two threaded gas pipes with end caps drilled to enable insertion of a wire which may be connected to a broken bulb or improvised electric match filled with black powder or match-head shavings to initiate a main propellant charge. Loaded in front of the charge would typically be paper wadding followed by ball bearings or other projectiles. A similar improvised muzzle loading gun was used to kill a police officer in South Korea in 2016.

Edit: More improvised firearms have apparently been found at the suspect’s home:
