So you are certain that if 100 shooters were provided with identical firearms and shoot with flat triggers and then with curved triggers ((or vice versa) that the results would be equal?
I like science. If you have a problem with me looking at interesting questions through a scientific lens then you can suck it, at a vacuum pressure of your preference.
Are you saying such a study exists?
How can you argue about scientific results that haven't been reported .. or collected?
It's pure speculation to say people who prefer one trigger might shoot better with a different one. If they shoot better, then most likely their preference would change, so 99% of the time, personal preference and performance will align.
i stand by my statement -- a DIRECT statement -- that it's subjective personal preference.
What makes one person shoot better with one trigger than with another, but the next person has the opposite results? I'll go out on a limb and say there are many reasons -- familiarity (used to one more than the other), length of the fingers, distance between finger joints, ergonomics of the trigger design is better for one person more so than the next, etc, etc.
Put a person in a manual transmission car, and they probably do better with an automatic. But, given time behind the wheel, they might be able to drive a stick better than they can an automatic while racing or driving a semi or bus.
There's no science involved, just common sense.
