"I have always thought part of his special genius was in making affordable and high quality firearms." So does Savage, Marlin, Henry, Remington and a lot of other gun makers. Ruger's guns aren't any or much cheaper than most other brands. Most are more expensive. The Mk I was probably the only innovative thing he did, as I can't think of another single thing he did that wasn't a copy of something else, except maybe the loading gate that releases the cylinder, but before I also though he was the first to design the transfer bar safety, so I don't know.
