Well it might have fixed your problem but cutting coils off a spring has the effect of increasing the rate of the spring not decreasing it. The formula for coil spring tension has the number of coils and the diameter of the coil on the bottom of the equation so that decreasing the number of coils will have the effect of increasing the spring rate.
In your case cutting the coils reduces the spring bind height allowing the FP a little more forward travel.
In my case I use the Geissele Super 3-Gun trigger, which has a 2 stage combined pull of 2.5# on an RCBS trigger gauge and no light strikes. Even with JP "yellow" springs on it and the pull reduced to 1.25# I experienced no light strikes.
