Hey there, just started up here and had a question for ya'll. I currently have a Ruger New Vaquero Special Edition, model number 5117, blued(looks black) with white handles, .45lc. Does anyone know what these are actually worth? It was a gift, and I'm considering selling it to buy another handgun. Also, is it possible to buy a .45acp cylinder for it? I asked at my local gunshop and they said it wouldn't work, but I swear I've seen interchangable cylinders. Thank you for your help!
