What YoYo said...
My 110 has a fully adjustable trigger, and will adjust down to about 1.5 lbs safely... (currently at about 2 to 2.25 lbs)
it "cleans up" as it goes down... and can even be lapped in for further smoothness.
no need to replace it, unless you feel you gotta... just be careful and watch the sear engagement... do the rubber mallet and "drop" tests... and it can be made into a very nice trigger...
