[1] During the 1940s, Abraham Trejo began independently developing firearms in secret.
However, when he was discovered by his father, Gabriel Trejo, instead of rebuking him, he supported him by assisting with the design and assembly of machinery to create barrel rifling.
[2] Having procured all of the necessary gunsmithing equipment, in 1948 they founded Armas Trejo SA in Zacatlán de las Manzanas, Puebla , which is why the Trejo logo is an apple.
The first weapon created by Trejo was the Trejo Modelo 1 "Tipo Ráfaga" and subsequently introduced different models until its cessation of production in 1971 due to the restrictions of the Mexican government.
[3][4] After the arms ban in Mexico, Armas Trejo S.A. rebranded to Industrias Trejo de Zacatlán S.A. and rededicated itself to the production of work tricycles and agricultural and industrial machinery.
