Actually, he has discovered the difference between a well designed and well tuned trigger vs inferior triggers.
A trigger is a trigger. The inferior part of the equation, is usually the shooter.
Triggerphobia seems to be a common thing these days, and you usually hear the complaints about other than SA triggers, from people who are inexperienced with anything but the SA triggers, and have never bothered to learn to shoot anything else (especially when you consider that it really only takes a little time and effort to learn to shoot DAO well).
If all you can shoot well with, is a light, SA trigger, then youre only doing yourself a disfavor, and limiting yourself.
Learning to shoot DAO, will do more for your shooting overall than pretty much anything else, and that transfers to rifles and anything else, not just hand guns. Its not hard at all to learn, and what you gain pays dividends, and is is well worth the little effort it takes.
As far as a combat trigger, they are really no different than anything else, and in many cases, the light,"tuned" SA triggers can be a detriment, and even a danger, especially in the hands of someone who doesnt practice realistically, and is basing their skills on what they do target shooting. Those light, tuned target triggers, have no place on a serious use gun. Whats even scarier, is one in the hands of someone who carries one, and doesnt understand that.
I have a good buddy who fits that last part. His Nighthawks are something to marvel at, but their triggers are WAY to light and sensitive, and have no place on a gun like that if its being carried (which he does). I shoot with him a couple of times a year, and we both have doubles with them when shooting them "realistically". I usually settle down with them after a mag or two, but they are his guns and he still has them every time we shoot.
He's a great guy, but I sometimes think he has more money than brains. He also has Pythons, and a couple of really nice S&W's, and he cant shoot them DA for crap either, which is how they are meant to be shot.
Like I said earlier, you are simply limiting yourself if SA is all you can shoot well with.
