Trejo Pistol is a term used to refer to a series of handguns produced in Mexico by Industrias Trejo de Zacatlán S.A., previously called Armas Trejo S.A. and of which, one of its variants, the Trejo Modelo 1 "TIPO RÁFAGA", is considered the smallest machine pistol in the world.^[1]

History

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. Between 1948 and 1971, a total estimate of between 80,000 and 100,000 weapons of all its models was produced.^[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. However in 2010, it returned to the production of weapons by introducing the 1 GT, 2 GT, 2 TM 3 VT and 4 models.^[5]

A total production of between 13 thousand and 16 thousand pieces was estimated.^[6][7][8]
