I just bought this last weekend and in studying my new (used) gun I noticed something very odd to me, having never owned a single action Ruger perhaps this is perfectly normal. Single action Ruger owners please chime in. The cylinder seems to be fitted with end shake limited by the bushing extension on the front against the frame which seems perfectly normal, and the recoil shield at the outer radius of the cylinder at the rear. (see the attached photo for the locations I'm describing.) It seems very strange to design a gun where the outer part of the cylinder drags the recoil shield to limit end shake, I'm accustomed to the extractor star performing this function on all the DA guns I own. Looking at the star through the open loading gate it appears you could easily slip a .015 feeler gauge between the star and the frame.
