Good Job! Great gun. You will find it is one of your most carried guns, compact, serious horsepower, low maintenance. I've carried one for 5 years most of the time as an off duty gun. You can write to Ruger for a free owners manual. Other than scrubbing out the cylinders and bore with any good gun cleaning solvent, a bore brush and some swabs...maybe hit a few high points with a toothbrush and a light wipe down with good gun oil (Mil-Tec...Break Free...for that matter, Marvels mystery oil seems to work fine, your new gun will likely outlast you.
If you think the guts are getting really cruddy, dissasembly is a breeze. Do a search here or wait for the owners manual. Option two is take the grips off and wash out the insides with Gunscrubber, a parts bath or even hot soapy water (Dawn works like a champ)...dry out with compressed air or a blow dryer. And then a couple drops of good oil in the workings, both ends of the crane and just work the action a few times. Remember, this gun was designed to be abused...REALLY abused and keep working. You will be hard pressed to screw it up. You will note the Rugers are a pretty popular item here. Theres a reason for that.
