Only ones I have had done are Remingtons. Have any of you guys got em where ya wanted without replacing springs in em? Thats the first thing my smith does is swap out springs when he adjusts them.
You don't need to replace any springs on a Remington trigger to get as light as 2 pounds. Which for a hunting rifle is plenty light and probably too light.
What should be done is a complete degreasing of every part in the trigger. Grease is a factories way of attempting to make a bad trigger smooth. Then get a mirror polish on the trigger connector and the sear at their engagement points with crisp and sharp angles.
For most this should still be left to a compitent gunsmith. It is very easy to mess up a trigger and shoot yourself or someone else.
