I was wondering if it would be possible to put an Uberti Cattleman II hammer (with retractable firing pin) into the frame of an Uberti 1872 Open top Revolver in order to have the 6 shot capacity of with the Cattleman II, but the esthetic look of the Open top model. Would there be any machining required to accommodate the extra mechanisms in the frame? The 1872 Open top in particular would be most feasible because of the fixed sights on the barrel and not on the hammer itself.
All constructive input is appreciated. Thank you.
