The Lahti L-35 is a Finnish semi-automatic handgun designed by Aimo Lahti in 1929, produced between 1935 and 1952. Designed to be manufactured autonomously in Finland, the pistol was used by the Finnish military throughout the Winter War and Continuation War. The L-35 was well-manufactured and worked reliably in cold conditions or when fouled. The use of a bolt accelerator helped making it reliable.

Although the Lahti is outwardly similar to the Luger P08, the firing mechanism is significantly different and more closely related to the Bergmann–Bayard pistol. The Lahti L-35 is a recoil operated, single-action, locked breech firearm fitted with a concealed hammer. The pistol itself is well sealed from dirt and ice but is heavy by modern standards. The Swedish copy was dubbed the Husqvarna Model 40 or m/40.
