For my "looser" guns - P320, P365, M&P9 - I use Lucas Extreme Duty gun oil, and Gun Grease when I know I am going to put a lot of rounds down the pipe in a short amount of time. The grease stays in place better when things get hot after 100 rounds in a matter of minutes practicing on steel. Tight Wilsons and CZs live on Wilson's Lite. A light film of grease goes on barrels at wear points. The Lucas grease stays put.
