I had a customer bring in a Kimber Solo that just started to fail to extract. I called Kimber requesting a replacement extractor spring. Guess what, Kimber no longer supports these POS. They will accept a trade based on MSRP of a current model if they have one in stock. The value of your POS Solo is based on the value of your new selection. In this case a RK MACO, now remember when the SOLO was purchased it sold for around $750 (dealer was around $600). Kimber wanted another $475 with the "trade". Kimber knew in 2012 when this firearm came out, that it might not work but with only one brand and weight bullet but they continued to sell the product. Now they no longer support it? I am always amazed that Ruger Firearms always, in some form or other, supports ALL the firearms they have made/sold in the past. My neighbor sent a Mini14 to "Chief Wahoo" for some custom work. "Chief Wahoo" botched the Mini up. Neighbor sent the Mini back to Ruger for a re-barrel. Ruger replaced the Mini at "no charge".
