Device for staging the pressure exerted on a trigger shank of a firearm, air or gas weapon

摘要

The invention relates to a device making it possible to have one or more steps in the pressure exerted on the trigger shank of a weapon. It consists of a movable part receiving the index finger exerting the pressure, which part is articulated about an axis b'. A pressure P2 exerted at a makes it possible to compress the spring until the faces f and f' come into contact, creating a mechanical stop. When the pressure P2 reaches the value of the pressure P1, the trigger shank assembly, articulating about the axis b, releases the mechanism M at c. IMAGE
