For about 5 years now I have used the same method for cleaning my pistols whether they be Sig Sauers or Glocks. I was recently told that if I don't shoot my gun on a regular basis that it may be to my advantage to run a patch slightly lubed with CLP through my barrel. The guy at the range who told me this said it preserves the barrel and when I do fire the gun that it makes the barrel a little bit easier to clean afterwards. Anyone use CLP to preserve their barrel? I guess it wouldn't kill me to try it, but I want to see if this actually serves a purpose. I have used CLP since day one, but I've never used it to lube/preserve the inside of my barrel.
