Have a Colt Rail Gun that just started giving light Firing Pin Strikes. What spring would you change, less than 100 rounds on this spring set. Ammo is Horady XTP's 230 gr +P. Hammer spring is a Wilson. Hit is center of primer. Gun has 1000's of rounds through it and several spring changes over the years. Gun is one of my carry guns and gets cleaned every month if used or not. 3rd and 5th round was light strikes in the mag. Cleaning is all parts removed all holes and passages cleaned, oiled and reassembled. I have carried the 1911 for 60+ years and this is the first light strikes where I did not have old spring or broken firing pin.
