Just picked up my matte nickel coach gun after waiting 10 weeks for it to come in. It is a beautiful looking little gun and the gun shop guy commented on what a nice piece of wood was used for the stock. I joked that for about $300 someone else must've got the knothole. Had only seen the black and stainless model up close and am very glad I went with the Silverado. Haven't shot it yet, but enjoying just looking at it for now. A small bit of the "preservative" (green gunk) it's shipped with is dried on the barrel and Hoppes #9 and oil didn't budge it. Any suggestions?
