SDI Hammer-Fired Pistols (FTH 223) Practice Test

Trigger discipline is about preventing unintended discharges by controlling the finger position until you are ready to shoot. The safest habit is to keep the finger off the trigger and outside the trigger guard, resting along the frame or alongside the pistol, so a stumble, snag, or surprise movement can’t press the trigger. That’s why keeping the finger on the trigger while moving is risky—any jolt or slip could depress the trigger and fire unexpectedly. Keeping the finger in the trigger guard when holstering is unsafe for the same reason; it can press the trigger during the holster draw or reholster. Placing the finger on the hammer is also dangerous, because manipulating the hammer can lead to an unintended release or discharge if the pistol is not in a controlled state.
