I have two new S&W revolvers, 686 and a 637. There doesn't seem to be anything in the manuals about lubrication. About all I have done is put a drop of oil on the cylinder. That seems to make it spin more freely, which seems like a good thing ... unless it's not for some reason. What do you guys do, if anything?

I use nyoil on the end of the ejector rod, on the yoke where it mounts in the frame, on the yoke where the cylinder slides on to it,ejector rod, ratchet, internally I remove the side plate and clean out old oil and relube all moving parts.
DONOT OVER LUBE GO LIGHTLY.

I put some moly on every metal to metal contact part. On the rear of the cylinder on the indexing star and lever too.

Ditto as above just a little will do.

I'm a bit fuzzy on what moly is. It looks like any number of lubricants contain molybdenum, from sprays to grease. I imagine you would use a bit of a grease there, is that correct?

[QUOTE=jpeschken;137656709]I have a can of "Moly Coat G" grease left over from my days of building engines. A DROP on the places metal rubs on metal works wonders.

You should be able to find it at a good hardware store or industrial supply house. Buy the smallest size they have, it's expensive and a little goes a LONG way.

Hi-

Check out this video from Midway USA. It goes over a detail strip, clean, and lubricate of a S&W revolver.

Cool, Thanks!

I can't seem to find that exact stuff online, but I'm thinking most any reasonably heavy-ish grease would do. I have some MIL-COM TW25B and some Frog-lube grease at home. I imagine those would be okay too.

Hi-
What you have at home "MIL-COM TW25B and some Frog-lube grease" is excellent you don't need anything else. You can even use rem-oil or any ptfe gun oil.
