Revolver actions usually work even better with a good grease on key points.
I used Super Lube synthetic Teflon grease on customer and my own pistols for years with excellent results.
Unlike liquid lubes, grease stays put and won't evaporate, run off, dry out, or wick out.
I've opened up customer revolvers as much as 10 years after servicing to find the grease still present and still working.
I'd think that a little grease on the bearings, and on key stress points like the hammer single and double action surfaces, and the trigger will make it even smoother operating and for longer periods without maintenance.
I'm working something out in my head - without grease. May have got one shim under control, the other one still ain't coming clear at all. Next time I clean the gun, I'll see if that first part works, at least.
I was at Ruger's site, found a way to communicate (supposedly) with the CEO. Asked him if he knew what his guys had in mind. No, I ain't holding my breath.
Yeah, I know I can just telephone Ruger customer service - but that's too easy.
I have added added Performer 8 to my life and shims to GP 100s and SP 101s both. I put a drop of oil on them to help hold them in place while I reassemble them. It seems to work for me but keep in mind I am not a master gunsmith.
