I was on the range Saturday when a student had a negligent discharge. Thankfully he had the muzzle pointed in a safe direction and no one was hurt. What he did was supposedly unload the gun then pressed the trigger to verify it was unloaded (to decock it) and it wasn't so it went off. He had been trained to do this. At post rangemaster school there was a negligent discharge that happened the same exact way.
WHY is this taught? Is there a training philosophy that requires that the gun be decocked by pulling the trigger? Seems to me this creates more hazard than if trained to keep the finger off the trigger until the sights are aligned and it is your intention to FIRE.
