Newly acquired data on firearms seizures at US ports of exit shows that trafficking dynamics vary significantly between the Caribbean and Latin America, and even within these regions. These differences include the number of seizures, the types of seized weapons, the illegal shipments’ modes of transport, and the seizure locations. Some of these differences are consistent with previous studies, while others are surprising.

The rate of violent deaths in the Caribbean remains well above the world average. Trafficking—including of firearm parts used to build privately made firearms (PMFs)—remains the primary source of small arms seized in the region. PMFs in the Caribbean vary widely in sophistication. Given their low cost and the increasingly diverse ways in which key firearm components can be acquired or produced—including through the use of 3D-printing and CNC-milling technology—PMFs have the potential to become a significant threat.
