It is not uncommon in a shooting investigation for a suspect or victim to claim that a firearm for some reason accidentally discharged during a scuffle or handling. For this reason every firearm that is received into the laboratory as being suspect in a shooting, must be examined and function tested.

The function testing is an examination of a firearm concerning its mechanical condition and operation. This would include testing all of the safety features in the firearm to determine if they function as the manufacturer intended. To determine the amount of trigger pull that is required to cause the firearm to discharge. And also determine if it is capable of accidentally discharging without the trigger being pulled, or if the firearm is capable of being fired at all.
