Ruger has been a good name for a long time. I think they may have some recent QC issues though.
A year or two ago I picked up a new Mark II.

Finally it jammed and I had to dissasemble it with a live round in the chamber. I didn't like that. I took it back to the gunsmith I got it from and he found some big burrs in the mechanism that had not been removed during manufacture. He took them off and then it test fired ok. I still had it sent back to Ruger for inspection. They looked it over and polished up the mechanism in a timely manner, at no charge. It functions fine now. It's a good gun. Initial QC was lacking, customer service was excellent.
If you like single action revolvers the Ruger Single Six is another I can recommend. It's great fun.
