So, after cleaning up the gun with Hoppe's #9 and then applying some oil to the slide, etc.. . .and the outside of the barrel, what are the final thoughts on oil inside the barrel. If I clean with hoppes and run patches through it until clean/dry, is that enough OR do I need to run a patch through the barrel with a few drops of oil on it. Should I only oil the inside of the barrel if I am putting the gun up for several months? Should I dry patch it before shooting?
