FAILURE !!
After putting in both springs (WOLF) (#9 & #9) I had light strikes shooting in slow fire double action.. Single action worked fine, but one out of a cyclinder of five wouldn't go off DA. I have taken out the hammer after market (#9), and put back in the stock (#11) spring. To bad, that light hammer spring sure made for a nice DA pull. Your mileage may vary but for MY 85, I can only use the lighter trigger spring. If you try this only do one spring at a time, then test fire and check to see if your guns still reliable. It has to go bang everytime you pull the trigger if it's going to be used for CCW or home defence..
Good Luck, CraigJS
