Unlike most other firearm actions, the break-action design does not require the barrels to be specially fitted to an individual action. Any barrel, with the exception of a Herrett barrel, that is made for a Contender will fit onto any frame, allowing the shooter to purchase additional barrels in different calibers for a fraction of the cost of a complete firearm. Since the sights are mounted on the barrel, they remain sighted-in and zeroed between barrel changes.
