I've got 4 Uberti revolvers which I completely disassemble and clean after each range session. I've found that all the parts inside the frame have residue on them and therefore I clean and reoil the same as the barrel and cylinder to ward off rust and corrosion. A coworker told me that he has a revolver that he has shot several hundred rounds through over a period of years and never took it completely down until recently and found no rust or corrosion inside except for a small spot of rust at the bottom of the mainspring under the grips. How come no corrosion inside the frame if it has residue on the parts after each shooting. How often do you pistol shooters disassemble the entire weapon?(time wise and number of shots fired).
