Thought this might be useful for new shooters or those who haven't shot in this type of "practical" competition before. My son and I shot a local match last weekend and it was his first. We had drilled the range commands previously, and practiced shooting and moving to different positions safely, and emphasized finger well outside the trigger guard and muzzle well downrange during movement. The first two stages he shot well and moved safely and carefully, but on the third there was a bit of a challenge with the 180 due to a barrier on the left and a required position forward of the position to the left and rearward of the barrier. As he moved back/left, he kept both hands on his pistol and the muzzle moved past the 180-degree line that is generally considered safe (unless the stage briefing specifically dictates otherwise and there are markers to indicate muzzle safe points). The SO was behind him and didn't see the violation, but I did, and since it was something we'd specifically gone over during the walkthrough (and because he did indeed break the 180), I chose to have him DQed for the match. He took it well, and I hope he learned. It's difficult to understand what it's like when the beeper/timer goes off in a match unless you've done it. Your IQ drops by 50 points when the adrenaline hits. Anyway, here's a video for any interested.
