When I disassemble the trip and immediately associated parts what is the collective wisdom for a lubricant? I have gun grease, traditional oils like RemOil and Hoppes, and Hornady spray dry lube.

When the gunsmith inspected the gun after my purchase I asked him to fully clean and lubricate the gun. He told me that he did remove the trigger plate and inspected the internals and also cleaned and lubricated them. Just a note: After this cleaning I experienced no problems with the lever. The gun was shot with probably 500 shells or more before I started having problems. All of those shells were my own reloads 7/8oz of #8 at about 1100 to 1200 fps.
