um. well i have heard things in the past about this. and i think that the spring is not needed its the fact that the hammer weights quite a bit and for better high rates of fire its needed. guns like egos have light hammers and do not need the extra spring.also the Low pressure ram u can buy for ICD achually does not have a spring. if its not broken don't fix it. lol hope it helps.
