About
What it is, and why it matters
The Mendoza PK-62 is a single-shot, break-action pocket derringer pistol made by Productos Mendoza of Mexico. It is a 'munisalva' (blank-firing) self-defense and signaling pistol chambered for small .22-caliber blank cartridges, with a compact frame designed for concealed pocket carry. The break-open design uses the Mendoza breech-closing system, and spare cartridges are stored in a compartment in the grip.
Productos Mendoza, best known for arming the Mexican Army with the RM2 light machine gun, also built the tiny PK-62 pocket derringer, a blank-firing self-defense pistol that tucks three spare cartridges into a hidden compartment in its own grip.
Classified in the Mendoza catalog under both firearms and 'munisalva' (blank-firing) arms. The PK-62-3 variant stores three spare rounds in a holder at the base of the grip. Physical dimensions are not published by the manufacturer. Year of introduction (1962) is inferred from the '62' model designation, consistent with the company's dating convention (e.g. C-1934). The .22 Short caliber block represents the closest canonical rimfire base for the blank cartridge it fires.
