The guns are extremely similar. Neither has "low hammers", in the sense of "low wide hammers" that many guns have these days.. The Smokewagon does have a hammer that is slightly differently shaped, supposed to be like some certain 2nd Gen Colt hammer. Part of it is lower a tiny bit but I'm not sure what part, perhaps someone else knows. The Evil Roy has an action job. The Smokewagon can be bought with or without the action job (called the Deluxe). Both companies do have models that have low wide hammers, Taylors calls theirs the Running Iron, and Cimarron's are Thunderstorms, plus their new Pietta line with short strokes called Eliminators.
