On a NEW wheelgun, I recommend dropping a couple drops of good lube into the action as you cock the hammer...a couple ahead of the hammer (down into the transfer bar area) and a couple behind the hammer. Then work the action a few times, get that oil down in the guts.
On a used gun, especially older, taking it UTTERLY apart makes sense, as decades of old lube can form a cosmoline-like crud buildup in there that can be outright unsafe if it disables a hammer-block safety.
No full detail-strip needed on a new gun, although with a Ruger such a full takedown can be done without boogering frame screws.
