I owned a Ruger Police Service-Six 4" barrel. Practically identical to the Service Six. It was, based on Ruger's database, a 1985 Orange County Sheriff's revolver sold at police auction,(back when they did that type of thing)...for the semi-auto upgrades.
Like you posted, it is a a well built, solid, accurate, tough revolver.
The Police Service Six I owned had more of a bull barrel, with a thicker wall, but not by much at all. The Security Six, was more popular, and at $329 for the SS version....sounds like a reasonable price if the condition is solid.
Question. Are the grips original wood or rubber?
Still a great pistol. Not quite sure the relevancy of the "shop-guy" mentioning the date. Perhaps someone else can chime in.
P.S. OBTW,....I wish I had mine back.
