What is the other name for a shooter's trigger finger?

The term "Primary Safety" is not commonly used to refer to a shooter's trigger finger. The correct term associated with a shooter's trigger finger is "Control Finger." The trigger finger is specifically designated as the finger that is loaded with the responsibility of applying pressure to the trigger when shooting. This finger is crucial for precise control and accurate shooting.

In the context of firearm training, the shooter's finger should remain outside the trigger guard until ready to shoot. This practice is vital for safety, hence why "Control Finger" would be a more appropriate description for the finger's role in handling a firearm. The other options do not accurately capture the function or designation of the trigger finger within shooting contexts.
