This is on a Ruger GP100, but I assume S&W would be the same. I'm opening it up to do a spring swap, and don't know what grease to use. I have some Mercury marine grease with PTFE, or I could use some synthetic Valvoline moly grease, which should last for decades without any significant changes. I have both on-hand.

That is an easy question. NONE. ZERO. NADA. You use a very small amount of light oil on internal revolver parts. NOT GREASE.

fair enough. That's why I asked.I have some of the Lucas Extreme green gun lube oil, or some Tri Flow.

No grease. Not a good idea in normal use. Lube of the inside of the S&W revolver is properly done with ONE DROP of Break Free or similar gun lubricant on the finger, sparingly applied to the hammer pivot pin, the trigger pivot pin, and the rebound slide. The Ruger revolver is lubed in the same manner. If blue, one drop on the finger applied to the exterior and then rub around, finishing with a soft rag to remove excess so the lubricant does not “run.”

Grease in a revolver? No. A very light amount of oil is best for revolvers.

Revolvers are new-ish to me. I just have 2. A Ruger blueed GP100 4.2" .357, and my dad's old JC Higgins/High Standard 9 shot .22. That one is everyones' favorite to shoot.

For whatever reason, some folks just love RemOil. I loathe RemOil as much as any lubricant I've ever come across.

If you put RemOil inside a revolver, it will eventually gum up. After it has finished it's cycle of gumming up, it will turn to a hard, brown lacquer that almost needs to be chipped off.

It's my position that RemOil is horrendous and nobody should use it for anything, but to be much more specific, the inside of a revolver that very rarely gets opened and cleaned is amongst the worst possible places to use RemOil.



This is what RemOil does when dumped in to a S&W revolver and left to it's own devices.

Only what the manufacturer specifies -- OIL.

Too much of any oil will gum up the works. Just a drop...

There was a guy that used to come to the gun shows here many years ago . His claim to fame was that he was formerly the Armorer for the Dallas PD . He would do trigger jobs onsite . I saw him use some kind grease on a revolver . He used a syringe and it was clear and very thin . Just a drop or two . His double action revolver triggers were awesome .

True. I’ve never had any issues with Rem Oil, but I don’t flood the insides of my guns with any oil.

djohns6....he was using Super Lube.

As above, Synco Super Lube is a really great revolver lubricant.
These are full synthetic, Teflon bearing, clear-white lubricants.

The best for guns is the stiff grease, and the oil.
The oil is a thick oil-thin grease consistency that's excellent in pistol actions for long term lubrication.
Unlike most liquid lubes, the Super Lube stays right where it's put, and never drys out, evaporates, runs off, or slings off.
I've opened up customer revolvers I'd serviced 10 years prior and the Super Lube was still in place and still working.
It had turned a light gray but was still going strong.

Usually, to service a revolver I'd put a few drops of CLP Breakfree on a soft toothbrush and scrub all surfaces inside the frame to deposit a very thin coating.
This was to prevent rusting not to lubricate.

I'd apply the Super Lube oil to all key working areas.
I'd put a dab of the Super Lube stiff grease on the hammer double action strut and sear notches, on the top and underside of the trigger, on the cylinder stop activating lug on the front of the trigger., and on the back and under side of the rebound slide.
This gives a glassy smooth trigger action, and unlike other lubes, it's stays that way indefinitely.

Where Super Lube is really good is in defense guns that may be used for years without a full disassembly and servicing.
Once as an experiment to see just how well a defense gun that got no service would work, I lubricated a Kahr Arms K9 with Super Lube and carried it in a fanny pack for a full year along with two extra magazines.
I never unloaded or did any cleaning other then to brush off any lint or dust.
After the full year I took it to the range and it fired all three magazines of Winchester Silver Tips without any problem at all.

I don't recommend doing this as a normal thing, I always give my defense guns extremely careful maintenance, but a lot of people buy defense guns and give then little or no maintenance.
I wanted to see if Super Lube could keep a gun reliable over a long period without the lubricant disappearing and leaving it dry.

It appears Super Lube can work as well in a revolver at least for 10 years.

I suggest you go here!!!!!
