The National Shooting Sports Foundation has released another of their training tips videos. This one is with Adam Painchaud of the Sig Sauer Academy. In this video, Adam demonstrates a training technique for working on your trigger finger discipline so that you will press and not jerk the trigger.
He is using a single action pistol but it would work with any pistol that doesn’t have a magazine disconnect. Adam starts by loading a round in the chamber and then removing the magazine. He then takes an aimed shot and then lets the trigger reset. The shooter follows this up with a dry fire aimed shot. If your front sight wobbles on the dry fire shot, you have found your accuracy problem.
