In a sense I'm repeating a much earlier posting
in this thread in which I differentiate between
auto and revolver.
Autos, field strip. But revolvers pretty much leave
alone except to dry fire a bit. Any problems will
quickly become apparent. Revolvers require
very little to almost no oiling. And that oiling,
using a very thin type like Rem Oil, consists of a
few drops to the innards without taking off the
side plate. Repeat, a few drops.
Actually, if you get a revolver, probably a used one,
that is oozing oil, get rid of all that oil. Gun Scrub it
out.
Oh yeah, certainly look down the revolver bore
and maybe put a patch through it.
