Notes
The Trejo pistol line is best known for the Modelo 1 'Rafaga', a select-fire .22 LR machine pistol. The Modelo 4 is the least common of the classic Trejo models. Armas Trejo halted firearms production around 1970-1971 under Mexican firearms restrictions and resumed manufacturing in 2010 with modernized GT/TM/VT variants of the original designs.
Background
Abraham Trejo built his first firearms independently in the 1940s, with his father Gabriel fashioning the machinery needed to rifle the barrels; the family workshop in the apple-growing town of Zacatlan grew into one of Mexico's few domestic pistol makers.
