They are a little different. The Cabelas gun has a transfer bar, a 5 1/2" barrel, and standard action. The Cimarron has no transfer bar, 4 3/4" barrel, factory short stroke, and action job. Both have low wide hammers and checkered Army grip.
Did anyone have documentation of makers using octagonal barrels on SAAs back in the 1800s? If not then illegal to use.
