This is a naive request. There is plenty of tech that could create new, innovative weapons. Personal tasers for everyone, charged with USB. Peppersprayers with chemical encoding to identify assailants uniquely. Weapons that can only be used by one person. The problem is these are NEW weapons and they do not in any way reduce the current supply of weapons. The current supply of weaponry is deadly, cheap, easily available, and apparently, no law can be created to reduce or inhibit the current supply. Under those circumstances, adoption of any new tech will be tiny and unimportant. Gun violence is a political problem, not a technological one. Once the groundwork is laid for political action to occur, then and only then can it move into the realm of a technological problem.
