Big advantage of NY-1 replacing standard trigger spring in conjunction with standard 5.5 pound connector is firm pull resistance from the beginning of the trigger stroke. This can indeed help prevent a premature discharge.
Huge advantage is that if opposing counsel tries to say you fired by (unjustifiable) accident instead of with justifiable intent, they're going to have a HELL of a time convincing the jury you were negligent if the gun had the NY-1 on board.
Another advantage is that the NY-1 seems to be a good bit sturdier than the standard trigger spring.
Give it a try, see how it works for you, and feel free to get back to GATE and offer feedback.
