Weihrauch blank firing revolver HW 37

Weihrauch HW 37 – compact blank-firing revolver for self-defense

The Weihrauch HW 37 is a compact blank-firing revolver in caliber 9 mm R Knall, designed for reliable self-defense. Its design is based on the classic American revolver style. Short, handy, and well-balanced, it fits securely in the hand and can be carried discreetly.

Particular attention is given to the newly developed trigger mechanism. The trigger operates smoothly and controllably, making handling easier and particularly interesting for female users. All central functional parts, such as the hammer and trigger, are made of steel, ensuring clean operation and durable mechanics.
