No one is penalized if everyone has to play by the same rule, if everyone has to shoot a 2lb+ trigger, there's no penalty. That's like saying the 3200fps limit is a penalty because you want to shoot something faster, as long as everyone has to follow the rule, it's not a penalty.
Hair triggers are a safety issue, period. It only takes a tiny movement to send a round very far off target at these distances, it doesn't have to be someone loading a round before they are getting into position, or shoving a finger in a trigger before they are in position. I've seen guys follow all the rules, not load a round or get their finger in the trigger before on target, and something happens (dust in the eyes, wasp sting, etc.) and takes them off target and their hair trigger sends a round off target. It happens, it just hasn't happened to you yet, can it happen with a 3lb trigger, sure but way less likely. We should not be using benchrest weight triggers in such an uncontrolled environment.
I can't count the weekend warriors that I've seen with light single action handgun triggers that swear they are trained and ultrasafe and the first round out of their holster in a shoot house with a little stress goes into the floor or ceiling. Sooner or later something happens that gets everyone out of the comfort zone, when it does, a hair trigger makes the odds of an ND much higher.
Safety is EVERYONE's responsibility, if you see someone being unsafe, and don't say anything YOU are the problem and should be penalized. Again I said if anyone in the squad saw it and didn't say anything penalize them as well, I did not say penalize the whole squad just because they were there.
I have to say this about the "hair" triggers. I run a really light trigger so does my wife. But I have to say that the new triggers that have come out recently are vastly better than those made even 5 years ago. I can set my finger on my trigger even lightly tap it and it wont break. I can tap it from the side and it wont break. I marry my finger to the trigger and pull it and it breaks at a very light weight. My old jewel would break cleanly but I had to be a little more careful with it. I feel like even though the amount of force it requires to break the shot, it takes every bit of it to the point that it feels heavier than the old triggers used to feel at the same pull weight if that make sense.
