In a local gun store today I saw a Smith & Wesson 4003TSW in great condition. They have it listed for $650. It has 1 magazine and the blue plastic box. Looking on Gun Broker I see them selling for less and one has listed multiple times for $600 and is unable to sell. $650 appears to be too much.
Question 1. Is the 4003TSW a great gun to shoot?
Question 2. What is a good price for the 4003TSW?

Any help is appreciated.
