Unlike some, I have never felt the need to "break down" a revolver
for cleaning. I must say all mine are stainless so I have fewer worries
about damaging the finish or anything rusting due to benign neglect.
This does not mean I have never taken off a sideplate. I also repair
laptops and have done small electronics and mechanics for decades.
I just don't think it's necessary for the most part.
To clean I mount the gun in my gun cradle/vise using an old
t-shirt. First facing away with the cylinder open. I then chuck
a PLASTIC .44 or .45 brush in a bat-drill and put a solvent soaked
patch over the brush. At a fairly low speed I run the combination
into each cylinder hole holding the cylinder with the left hand to steady it.
For extra dirty cylinders you can use JB bore compound which will polish things up.
Repeat as necessary. Then with your short pistol rod and a plastic jag run a dry patch thru each hole/throat.
The face of the cylinder, I just wipe off with the cleaning compound
to remove the loose stuff. It will remain black.
Turn the gun around so you are looking down the business end
of the barrel. Make sure your rod has a bore guide on it. Mine
is aluminum but plastic is good too. This is to ensure to rod
does not touch the bore. Repeat the above but this time with just
a patch on the jag. You will find the best combination of cleaning
products that works for you. I use JB, Butch's Bore Shine, Barnes
CR-10 for heavy copper fouling and yeah, Hoppes.
"The S&W Revolver - A Shop Manual" by Jerry Kuhnhausen
is one of the best smithing books for the S&W but is sadly
out of print. If you can find a copy, pick it up. Since it was written
in 1985 it obviously will not cover more recent developments.
There are a couple of others out there but since I have this one I have
never looked at them.
