Private ownership of firearms is restricted to the home only.[38] Only Mexican citizens and foreign legal residents of Mexico (FM2 holders) may purchase and keep firearms in their place of residence. The Directorate of Commercialization of Arms and Munitions (Dirección de Comercialización de Armamento y Municiones – DCAM) is the only outlet authorized to sell firearms and ammunition in the country and it is located in Mexico City near SEDENA’s headquarters.[39][40] The transfer of ownership and the sale and purchase of firearms between individuals is also permitted, but the transaction must receive authorization from the Secretariat of National Defense by both parties (buyer and seller) appearing in person along with the weapon, to conduct the transaction in accordance to requirements set by law.[41]
