The invention relates to a small arm system with an exchangeable barrel. The aim of the invention is to provide a small-caliber small arm for high-speed bullets (10) with an effective silencer. To this end, the arm is provided with an exchangeable barrel that is designed for a bullet (10') whose caliber is substantially larger than the bullet (10) for the small caliber but which has the same length and the same base dimensions. The bullet (10') for the exchangeable barrel is designed in such a manner that the projectile (7') has a muzzle velocity in the ultrasonic range while being sufficiently heavy to supply a sufficient muzzle energy. The different bullets (10, 10') for the original barrel and for the exchangeable barrel are designed differently so that a confusion of the bullets (10, 10') is impossible since the respective bullets (10, 10') cannot be completely inserted into the bullet chamber (20, 20') to which they do not pertain.
L'invention concerne un canon de rechange, destiné à améliorer l'efficacité du silencieux sur une arme à feu de poing, de petit calibre et à cartouche (10) rapide. Ledit canon de rechange est destiné à une cartouche (10') de calibre beaucoup plus important, mais qui présente la même longueur et la même dimension de culot que la cartouche (10) de petit calibre. La cartouche (10') pour le canon de rechange est conçue de manière à ce que le projectile (7') ait une vitesse initiale subsonique, mais soit suffisamment lourd pour fournir une énergie initiale satisfaisante. Les cartouches différentes (10, 10') pour le canon d'origine et pour le canon de rechange sont conçues de telle sorte qu'il soit impossible de les confondre, car les cartouches respectives (10, 10') ne peuvent pas être logées complètement dans une chambre (20, 20') inadaptée.
