The Swiss Karabiner Model 1931 (K31) was developed by Waffenfabrik Bern as a refined evolution of the earlier Schmidt-Rubin straight-pull system, incorporating a shorter, stronger action and improved manufacturing techniques. Adopted in 1933, the K31 featured a redesigned straight-pull bolt with locking lugs positioned at the front of the action, significantly enhancing rigidity, accuracy, and overall durability compared to its predecessors. Chambered in 7.5×55mm Swiss (GP11), the rifle became renowned for its exceptional precision, smooth operation, and consistency, making it one of the most accurate standard-issue military rifles of the 20th century. The K31 served as Switzerland’s primary service rifle through World War II and well into the Cold War, reflecting the nation’s continued emphasis on precision marksmanship and high-quality arms production. Today, the Swiss K31 is a highly sought-after collectible rifle, prized for its outstanding accuracy, innovative engineering, and the exceptional craftsmanship that defines Swiss military firearms.
