A 32" Model 21 can be made to weigh from 7 1/2 to 8 1/2 pounds depending on the wood variety and configuration. Barrel wall thickness will not vary, even in the Magnum and Duck models. Unlike the Model 12 Duck, the Model 21 3" chamber barrels are the same as other models. A 32" Duck or Magnum model would be as good a choice as any other model for a base competition gun. You haven't told us yet whether you are looking for a vent rib gun or a matted rib gun.
