Bro, I figured out a long time ago that an easy trigger was good news and bad news. By "easy trigger," I mean a very light and/or a very short pull.
Good news is, they're easy to shoot.
Bad news is, they're easy to shoot.
With a double action first shot on a TDA (Traditional Double Action), the danger of an unintentional shot under extreme stress comes after the first shot has been intentionally fired. This tends to be a rare occurrence, usually happening in the situation where a shot has had to be fired intentionally...the danger is now over...and the user unintentionally fires (or is falsely accused of unintentionally firing) one or more unjustified, negligent shots. (Remember: "there's no such thing as a justifiable accident.")
Double action only trigger system guns in their various formats were expressly designed to prevent that.
While I personally am comfortable with a TDA design, and particularly one with a short reset trigger, some others are not. This is why the manufacturers have given us multiple choices in this regard.
The choice, however, is up to the individual (or the institutional purchasing entity), and must encompass a realistic, honest assessment of the predictable skills of the given user(s) under stress.
Recognizing that answers are more complicated than questions,
