Trigger

The term "trigger" refers to a device that activates or sets off a sequence. Specifically in the context of firearms, a trigger is a mechanism that actuates the firing process. It often resembles a small, metal, curved rod located on the lower front part of the gun, typically squeezed by the pointer or index finger. An accurate depiction would feature the trigger as a component of a firearm, possibly a handgun, shown in isolation or as part of the entire gun.
