Is Brass Knuckles Legal in Mexico After the 2026 Regulatory Updates?

No, brass knuckles are classified as prohibited weapons under Mexico’s Federal Law on Firearms and Explosives, rendering their possession, manufacture, or sale illegal nationwide. The 2024 amendments to Article 10 explicitly expand the definition of “prohibited arms” to include “any device designed to inflict injury through mechanical force,” encompassing brass knuckles. Violations may result in imprisonment under Article 83 of the same law, with penalties ranging from 5 to 15 years. Travelers found carrying brass knuckles risk immediate confiscation and criminal prosecution, as Mexican customs authorities enforce these restrictions rigorously.
