Live vs. Dead
A live trigger means that even once the first shot is fired, the trigger doesn't stop moving. It is either moving forward to reset or coming back to fire another round immediately. This includes when the shooter is transitioning between targets. The trigger keeps moving. This is in direct contrast to the "dead trigger" technique, wherein the shooter allows the trigger to go forward to reset, pauses, confirms sights on the target, and then begins the lengthy double-action pull again. The speed advantage with the live technique is significant on targets inside 15 yards. On this writer's range, engaging a single target at 7 yards using the dead trigger technique produced split times averaging 1.05 seconds for the second shot. A live trigger reduced split times to .35 seconds. Two targets spaced 6 feet apart, with one round fired on each, produced dead trigger splits of 1.20 seconds, and live trigger splits of .55 seconds, with perfect hits for each. Split times like that will make a huge difference in a match score.
