Trigger pull

Trigger pull is the term used for establishing the amount of pressure required to be applied to the trigger of a weapon to discharge it, which can be important in cases where a weapon may have been discharged accidentally.

Once the trigger pressure has been calculated, it can be established whether it is within the expected range for that particular type of weapon or, for example, "dangerously light". Tests can also be carried out to establish whether the weapon will discharge without pressure being directly applied to the trigger, for example, if the weapon has been dropped to the ground.
