Cleaning and lubricating a gun after shooting is common practice. How about "just lubrication", when the gun has not been fired for a long period of time sitting in a drawer, or stored for months, even years? I live in the desert where it's always very dry (average humidity is 9%) so rust and corrosion from the elements, especially in house, are almost nonexistent. My carry gun gets lubricated (patch through the barrel & wipe down) once a month due to principle, my stored guns maybe twice a year, need it or not. I've never had a handgun or rifle that didn't perform flawlessly practicing this routine, nor have any of them ever experienced a speck of rust or any sign of corrosion. What is your maintenance routine? Please share.
