Now we'll cover revolvers. First, most people don't take the side plates off of their revolvers when they clean them, so we'll cover that type of lubrication first. After you have cleaned your revolver's chambers, barrel, and external surfaces, a light coat of oil is recommended. The cylinder turns on a shaft that can be called the crane or yoke. You can put one or two drops of oil at the point that the cylinder and yoke join. Tip the revolver muzzle up as you apply the oil and rotate the cylinder after each drop. If you continue to hold the muzzle up and turn the cylinder for a few moments after you apply the oil, it will run to the rear of the moving surfaces.
Next, you can apply one drop to the hand that rolls the cylinder, while keeping the muzzle pointed upwards. Immediately after applying the oil, cycle the action several times. Open the cylinder again and put one drop of oil on the rear of the cylinder in the center where it turns against the frame. On S&W revolvers, there is an ejector rod lock up in the front of the ejector rod. Place one drop of oil into the end of the ejector rod. Once again, tipping the muzzle upwards and turning the cylinder will help spread the oil to the moving surfaces. With the cylinder closed, cock the hammer. Put two drops of oil along each side of the hammer while it's cocked. Now cycle the action twelve times double action to spread the oil, Turn the pistol upside down. Put two drops of oil on each side of the trigger. Now cycle the revolver twelve times while it is upside down to spread the oil. This is about as good a job of lubrication that can be done if you do not remove the side plate. If you do not remove the side plate at all, I would recommend that you have the pistol completely disassembled at least annually by a pistolsmith and thoroughly cleaned and lubricated. If you carry the revolver daily, the complete disassembly should be done semi-annually at a minimum.
If you can remove the side plate and do a complete disassembly of your revolver, you should do so every 500 rounds. In this case, you can use a light weapons grease on the internals. Again, a very light coating. Don't over do it, you're not greasing the front end of your car. You should also remove the cylinder from the yoke when you do the complete disassembly so that you can clean the yoke shaft and the inside of the cylinder area that turns on the yoke.
