I have successfully installed hammer shims on my GP's to eliminate the hammers rubbing frame. Now I'm planning on installing hammer dog shims to lessen the slop in the hammer dog. After pushing the hammer dog to one side and measuring with feeler gauge the gap measured .019. It seemed like quite a lot of slop to my untrained eye. I know I need to allow a minimum of .002 on each side of the dog so I'm planning on installing a .007 on each side of the dog. How many of you GP owners have bothered to do this and did it make a difference? Is there a reason why Ruger leaves this much play in the hammer dog? On these cold winter days I like tinkering with the easy stuff to pass the time and I'm not sure if it will make a noticeable difference in the action.
