Hi Skeet, welcome to the forum. Yes, please do a fieldstrip and good cleaning, then lightly lube those areas that have frictional contact with the appropriate grease or oil. This lets the gun work properly and lets you inspect for problems and small shavings or foriegn material that may have been left from the manufacturing process. Also check the barrel for obstructions, etc. Iowegan has an excellent guide to these pistols called the IBOK for Mark Guns. You will have to email him for a copy.
When you get a chance, stop in the New Members forum and introduce yourself. Enjoy your new Ruger!
