The KwK 40 L/43 was mounted on the Panzer IV from April 1942 until June 1943. All 225 vehicles of the Panzer IV F2 mounted the L/43 with a ball shaped muzzle brake. About a 1,000 out of the 1,687 vehicles of the Panzer IV Ausf. G mounted the L/43 with a double baffle muzzle brake. The StuG III with the L/43 gun was designated as Ausf. F. of which only 120 were equipped with the L/43 (the remaining 246 having the longer KwK 40 L/48 version). All StuG III production runs through Ausf. F/8 to G mounted the longer L/48. The 780 original Jagdpanzer IV tank destroyers mounted the Pak 39 variant of the L/48 gun, the later Panzer IV/70 mounted the StuK 42 L/70.
