The 4.2 cm Pak 41 was a light anti-tank gun issued to German airborne units in World War II. This gun was externally similar to the 3.7 cm Pak 36, and used a modified version of the latter's carriage, but used the squeeze bore principle (in German called Gerlich after Hermann Gerlich who developed the principle in the 1920s, reportedly for a hunting rifle) to boost its velocity, and hence armor-piercing ability. The bore had a diameter of 42 mm at the chamber, but tapered down to 28 mm at the muzzle.
