"Is Ruger still in business?"
Yes.
"I have looked at every gun shop within 50 miles of Raleigh for a new Ruger without success. Are they that far behind in production?"
Ruger, like all smart businesses make products that sell quickly,, and thanks to modern times, and the larger buying market,, "black, plastic, tactical, bottom feeding, semi's" get the lion's share of the stuff being made.
A company is in business to make money. They must build & sell a product at a profit to stay in business. Anytime a product gets built, and sits in a warehouse due to slow sales,, it costs money. (Storage, inventory, record keeping, security etc.) But when you can build & ship as fast as you can make a product,, you focus upon that first.
You need to either widen your search area or expect to pay a premium for your desired model.
