More frequently shooters compete internationally against each other in a separate "20 gauge"-discipline, particularly at "Combined game shootings". Anyone who enters this competition using a shotgun with identical characteristics to that of a 12 gauge has a huge advantage

The 20 gauge barrel is offered in Game and Competition models. Its low profile action enhances a perfect silhouette. Total weight, balance, weight distribution and the rib of the 20 gauge are identical to that of the 12 gauge shotgun. 12 gauge and 20 gauge barrels are compatible. image above:
