I may possibly trade a Uberti 1873 Cody-Matic in 357/38- 20 inch octagon barrel. Not sure if your familiar with Cody-Matic. If not, Cody Conagher (http://codyscowboyshop.com
) takes a new Uberti and and short strokes it. Not a retrofit but a true gunsmithed custom.A new Cody-Matic runs $1,500.00. Excellent condition with box.
