Nice looking Shield! I use Strike Hold on most of my guns. It puts a coating on the metal that adheres and is hydrophobic. It is also a dry lubricant that carbon does not stick to. After shooting you can usually just wipe your gun clean with a dry cloth. I do use MPro7 grease on the slide. But, maybe you are more traditional. I suggest making your own CLP from inexpensive ingredients. The concoction is called Ed's Red Gun Bore Cleaner. It can be made by the gallon from ingredients found at a hardware store or Walmart.
