Attention! When the trigger pull is set below 1kg, firing occurs when the weapon falls. This is due to the construction of the trigger mechanism, where the pivot point of the trigger is not in the center of gravity and the firing occurs by the movement of the trigger by the inertia of the mass.
When setting the lowest trigger, a shot may occur when the weapon is unlocked and it is necessary to take this fact into account. For the above reasons, we do not recommend setting low pull for hunting weapons, and for sporting weapons, these parameters must be taken into account.
