Trejo pistol

Trejo pistol is the umbrella name for a series of small blowback machine pistols built by hand in Puebla, Mexico, from 1948, the best known of which — the Modelo 1 “Tipo Ráfaga” — is among the smallest select-fire arms ever series-produced. Gabriel and Abraham Trejo built the tooling to rifle their own barrels rather than buying it, and the resulting pistol is a straight-blowback .22 Long Rifle design with a selector on the slide switching between one shot per pull and automatic fire from an 8-round single-stack magazine, cycling fast enough to empty that magazine in well under a second.

Later models scaled the same layout up: the Modelo 2 held an 11-round magazine, and the Modelo 3 and Modelo 4 moved to .32 ACP, .380 ACP and, briefly, 9 mm. Production stopped in 1971 under Mexican arms restrictions, after which the firm turned to work tricycles and farm machinery; it resumed building the pistols in 2010 with updated GT and TM versions of the same models. An estimated 80,000-100,000 Trejo pistols of all models were made across the pre-1971 run.

The entry above records the original Modelo 1. No manufacturer specification sheet or official production record is published free online for any Trejo model: every figure here comes from Wikipedia’s own specifications table, which is itself compiled from a Guns.com feature article and a Spanish-language enthusiast blog rather than from Industrias Trejo directly, so mass, length, barrel length and magazine capacity are recorded as estimated rather than verified. The cited cyclic rate is a published range, not a single measurement. No freely licensed photograph of any Trejo model turned up in a search of Wikimedia Commons, the Smithsonian Open Access collection or the DVIDS US military archive, so this entry carries no gallery and no hero image.
