Are Brass Knuckles Illegal in Colorado

Brass knuckles are illegal in Colorado. State law (C.R.S. 18-12-102) bans both the possession and sale of metallic knuckles, defining them as dangerous weapons.
Possession can result in misdemeanor charges, and using them in a violent act can escalate the offense to a felony.
Even plastic or polymer versions are considered prohibited if designed for striking. Colorado takes a strict approach to concealed weapons, so it’s best to avoid owning or carrying brass knuckles anywhere in the state.
