Instructions come with the trigger. There is an "E" clip that you need to take off to pull the pivot pin out. Watch the "E" clip that it does not go flying when you take it off, you will reuse this and the pivot pin. When I remove these types of clips I use a small screw driver and cup my hand over the other side of it so when it comes off, it will pop into my hand or fall on the work bench. I do not remember the spring going flying. There is only one spring and it is between the trigger and the action. I think it just falls out once you remove the pivot pin. You will need to install some screws into the new trigger before replacement. There is instructions on how to install the new trigger. The most time was getting all of the screws set just right. You will need to adjust then try, adjust then try until you get it just right. I have mine adjusted down to 1 pound with very little creep and over travel. It did take a little patience to get it adjusted down that close and still be safe. If you are not as picky as I was, then it would be much quicker. I have every adjustment as fine as I could. When you make an adjustment on one screw, it will affect the way one or more of the others work and depending on the screw, the safety. Once I got it just right, I degreased it; then took some of my wife's finger nail polish and "cemented" the screws into place. I waited until the polish set then reapplied some rust preventative. If over time, it wears and needs readjustment, I can break the finger nail polish bond and readjust, but it will keep the screws from turning until I decide to do so. It really is not difficult to do, just take your time with the adjustments and be patient. Good Luck and Good Shooting.
