My ruger has about 2500 rounds through it and I think it is time for a real good cleaning. According to the manual, takedown can be done by the owner, and is part of the maintenance recomended. Last few times I cleaned it I noticed a lot of residue buildup on the front of the cylinder where the ejector rod goes into the cylinder.1) Has anyone ever tried to take one down?The manual is pretty specific, and takedown is recomended as part of maintenance and I can get to the point of taking out the mainspring assembly. Where I have trouble is taking out the Hammer Pivot.2) Has anyone tried this?3) Or alternatively is this just a VERY bad idea.Here is a link to the manual:Ruger Page Not Found all.
