Selon les données existantes, la République de Guinée ne compte pas parmi les États ouest-africains les plus touchés par la prolifération des armes légères et de petit calibre, y compris les armes à feu artisanales. Mais les autorités nationales savent que ce phénomène en constante évolution pose des problèmes sécuritaires et sociétaux considérables qu’elles s’efforcent de cerner et de régler depuis quelques années.

The proliferation and diversion of privately made firearms and other non-industrial small arms and light weapons pose a growing threat to security across the world.  Some regions have attempted to regulate rather than prohibit manufacturing, but these efforts are hindered by implementation challenges and diversion. Additionally, new technological developments and the ease with which information and expertise can be shared online have decentralized production, contributing to the global diffusion of the tools and skills necessary to build small arms and light weapons.

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.

Improvements in technology and information sharing have transformed PMFs from crude, impractical homemade devices of limited value to most criminals into highly functional weapons that are increasingly viewed as viable substitutes for factory-built firearms. The effectiveness of national and international small arms control regimes are gradually being eroded; the lack of serial numbers on such weapons, for example, undermines tracing efforts that have been a cornerstone of investigations. 

The use of improvised explosive devices (IEDs) in West Africa expanded dramatically over the last decade. IED-building networks have established material and training links across conflict areas in West and Central Africa, and their designs have remained constant and inexpensive throughout the region—helping to increase their use in attacks against domestic and international security forces, UN peacekeepers, and civilians.
 

Craft firearms are deeply embedded in West Africa’s culture and history, often being used for hunting, livestock protection, and in traditional ceremonies. However, these firearms are increasingly being used in crimes and civil disturbance.   

The Caribbean region suffers from some of the world’s highest rates of violent deaths, at almost three times the global average, as well as one of the world’s highest rates of violent deaths among women. Firearms are used in more than half of all homicides, with this proportion reaching 90 per cent in some countries. While much emphasis has been placed on firearms control at both the political and operational levels, illicit firearms, and the dynamics of illicit arms markets in this region have received little research attention.

Although the number of craft-produced small arms and light weapons is difficult to estimate, they are prevalent and range broadly in sophistication and quality.

Improvised and craft-produced firearms remain an important source of firepower for a wide range of actors, including tribal groups, poachers, criminals, insurgent groups, and even some states and quasi-state groups. In various locations, these weapons account for most of the firearms used in crime; in others, their production is institutionalized, providing essential income for local gunsmiths.

Criminals purchase weapons unable to fire live ammunition legally and at low costs across Europe, converting them into lethal firearms with little to no training or expertise. The Small Arms Survey report From Legal to Lethal: Converted Firearms in Europe provides a detailed examination on the topic.
