Uberti, makes a slightly better model, but it is easier to get parts and spare cylinders for the Pietta.
The cap and ball cylinder is legal for some hunting in PA, such as groundhogs and coyotes.
The 45 conversion to centerfire cartridges is legal for deer and bear in most of the state. But the conversion cylinders are not made for hot loads.
The cap and ball cylinder models were legal to hunt deer 25 years ago in PA. Until 40 years ago, Remington labeled it's percussion caps as centerfire. As did Winchester, UMC, etc. Whether a percussion cap model comes under the definition of center fire now is subject to no small debate.
