STOP!! Bill N. is right--don't put Slide Glide or any other grease in a revolver action, especially one that you might need to rely upon for self-defense.
Do yourself a big favor and don't take your gun apart. Seriously. Clean the gun externally, including brushing the chambers and bore, make sure everything is clean and dry under the extractor, and that's it. Maybe put one drop of synthetic motor oil on the yoke barrel where the cylinder turns. I wouldn't even put oil in the action--you really don't need it on a carry gun.
FYI, in case anyone was wondering, I do follow my own advice on this! My primary carry J-frame (a S&W M-337) has never had its sideplate off! The yoke screw has never been loosened, the factory threadlocker is still in place. The gun functions perfectly, the DA is heavy but perfectly fine for a carry gun, and I know it's going to function in the unlikely event that I ever need it.
That's my advice.
