Depending on the persona, a Rossi Model 92 (Winchester 1892 clone) would be a great rifle. I would look for somethig that holds 10 shots. a companion revolver, like a used model 10 would be a great way to start. Although a shotgun is not manditory, there are plenty of pre 1950 style pump shotguns available for modest cost at gun shows ana at many gunshops. The 10 foot rule is pretty forgiving for revolvers so you don't need a 5 screw S&W, a more modern used S&W will serve just as well.
