It was produced in several variants: a "I" version for infantry use, a "P" version for use in tanks (to cover the dead areas in the close range around the tank, to defend against assaulting infantry), versions with 30°, 45°, 60° and 90° bends, a version for the StG 44 and one for the MG 42. Only the 30° "I" version for the StG 44 was produced in any numbers.

- ==Description== It was a barrel extension that was bent at a certain angle. The idea behind the Krummlauf was that it would be fixed onto the end of the rifle's barrel, thus allowing the firer to shoot around a corner and avoid exposing their body to the enemy. It was mainly designed for use with tank crews, since it was difficult for them to shoot at nearby infantry without exposing themselves. However, the Krummlauf device was not effective and, when it did work, accuracy was incredibly poor. The Krummlauf device was unsuccessful and languished as a design and as a concept. Today, Krummlaufs are really only found in museums, but it did serve as inspiration for the modern-day Cornershot system, a similar Israeli design. The Russians developed a similar curved barrel for the PPSh-41, also

| - It was produced in several variants: a "I" version for infantry use, a "P" version for use in tanks (to cover the dead areas in the close range around the tank, to defend against assaulting infantry), versions with 30°, 45°, 60° and 90° bends, a version for the StG 44 and one for the MG 42. Only the 30° "I" version for the StG 44 was produced in any numbers. The bent barrel attachments had very short lifespans – approx. 300 rounds for the 30° version, and 160 rounds for the 45° variant–as the barrel and bullets fired were put under great stress. Another problem besides the short life-span was that the bending caused the bullets to shatter and exit the barrel in multiple fragments, producing an unintended shotgun effect. As a result, weapons designers experimented with small vent holes drilled into the Krummlauf's barrel in order to reduce pressure and recoil, allowing the discharged bullets' built-up gases to be released to slow the bullet's velocity as it turned to exit the barrel. Nevertheless, the Krummlauf's lifespan remained the same. The 30° model was able to achieve a 35x35 cm grouping at 100m. One of the biggest drawbacks of the small number (91 conversions) of Panzerjäger Tiger (P) casemate-type tank destroyers was that in spite of having a 88mm anti tank gun, the initial Ferdinand version of the Elefant did not have a forward-facing hull mount machine gun to handle enemy infantry. Hence, the Krummlauf was fitted with the Stg44 Gun and used by the tank crew as a machine gun. According to popular belief, this weapon was also Hitler's weapon of choice.
