Basically, it allows you to pull the trigger harder than before. The spring on the triggers of most of the supermax guns is there to prevent you from firing an overpressurized gun.
But anyways, I used to wrap the springs in ribbon and then tape... you could just put hotglue there too, as you've said.
Just find a way to make the spring on the trigger a rigid thing, with no tendencies to compress (well.. a great deal,) and you're done.
Doesn't really reduce the trigger pull.. Just makes it more responsive.
