Weapon crackdown

 I was thinking how to reduce the risk of undocumented weapons. 

You could use high punishment and low punishment. For example if you produced your own weapon you're subject to punishment but if you didn't brand your weapon then its definitely more malicious, so at least brand your weapons as yours. 

If the people wanted to buy undocumented weapons as well as the info about its whereabouts (in order to track them down), attributable weapons are clear from unbranded weapons so the people could focus more on the unbranded weapons.

False brands are subject to intellectual property violation, but its illegal?, slander and defamation yes but also trademark leeching too. The violation wasn't necessarily against the trademark owner but against justice.
