I found a used .44 Special Thunder Ranch at a local gun shop. Condition is virtually perfect. Not a mark on it. In fact it may be new. I have not yet asked the shop owner. In the wooden case. No cardboard carton, etc. Priced at $500 plus tax. I would like a nice .44 Special. Is this a good price. Would it be better to look for a 4" M-29? It is fixed sights. Round blade front... wider than I expected. Didn't know any better and thought when I first saw it that it was a .45ACP. Suggestions, etc., appreciated.
