The European hunting culture brought out a gun, in which its whole facet wealth reflects itself: The drilling. Like no other gun, it reflects ingenuity and the art of gun making at its best. Over 100 years of experience and a long list of innovations, the name Krieghoff is practically synonymous with drillings. The Optima, the newest generation of drillings is no exception. The rich know-how of Krieghoff’s engineers and craftsmen combined with modern steels and machinery result in a slim and trim drilling with true “all-around” qualities.
