Hhmmm....I'm not talking lubrication here, but I know professionals who seldom clean their firearms unless they have some indication that the gun isn't functioning perfectly. Completely striping the gun apart & cleaning every little screw, nut & spring that fits to each major component of the firearm does little/nothing to improve on functionality.
However, each to their own liking.
So I won't be accused of not addressing the thread....I don't go to gun ranges. If I want to shoot, I borrow a gun & go out back.--Patrice
