Traditional firearms training often relies on the outdated rule that only the fingertip pad should touch the trigger, a concept this text argues is scientifically flawed. Because every shooter has a unique hand anatomy, rigid placement mandates fail to account for different finger lengths and joint movements. Modern research suggests that linear force alignment, rather than specific skin contact, is the most critical factor for maintaining muzzle stability during a shot. By applying principles of biomechanics and neurophysiology, instructors can move away from one-size-fits-all heuristics toward a more individualized approach. This evidence-based framework emphasizes smooth motor control and the isolation of finger movement to prevent disrupting the firearm's aim. Ultimately, the source advocates for a necessary evolution in training that prioritizes physics and human physiology over institutional habit.
