sounds like you have a build up inside that needs a complete cleaning. I never have liked spary oil for a gun, I like to place the oil directly where needed and if wiping down the outside I just put a couple drops on a gun cloth and wipe down the gun. Too much Oil is always a bad thing on a semi-auto especially if it gets cold.
