gun advice

So as some of you may or may not know I have a pair of single action army revolver's and am currently in the process of getting verious pieces of equipment to help make them better at what they do, I.E. shoot accurately, quicker on the draw, easier to handle and fire especially with one hand...

I'm looking to try different gun lubes, looking for something that keeps things running smooth and lasts a good period of time once applied. I heard some good things about synthetic motor oil, but upon further research wasn't so sure.
