The 39-2 is an excellent gun, and is very enjoyable to shoot. In my experience, the primary wear items are springs, notably the extractor spring and the recoil spring. Replacing them is not terribly difficult, and will cure 95% of extraction/stoppage problems. I notice that you mentioned the gun you are considering needs re-bluing. The frame is aluminum alloy, and was anodized, rather than blued. S&W will no longer refinish any alloy frame guns prior to current production generation guns, so a trip back to the factory for a re-blue is out of the question. If the anodizing process is not correctly done, it is not unheard of for the frame to melt during it, so you want to have it done by a pro who is experienced and careful. Fords is one of the few who will refinish them, and they usually do a superb job. Check out their prices for refinishing, and don't forget they charge extra for aluminum frame guns. Take that into consideration when negotiating price.
