The 10.5 cm leFH 18M (German: leichte Feldhaubitze "light field howitzer") was a German light howitzer used in the Second World War. The gun, less the carriage and shield, was also used as the armament of the SdKfz 124 Wespe self-propelled artillery vehicle.

[edit] History
The 10.5 cm leFH 18M superseded the 10.5 cm leFH 18 as the standard German divisional field howitzer used during the Second World War. It was designed and developed by Rheinmetall in after the war broke out in an effort to get more range from the basic leFH 18 design. A muzzle brake was fitted and the recoil system adjusted to allow the use of a more powerful charge and new long-range shell.
Generally it did not equip independent artillery battalions until after the Battle of Stalingrad in 1943. 53 units were also exported to Finland, where they were known as 105 H 33.
[edit] Description
It has a heavy, simple breech mechanism with a hydro-pneumatic recoil system. The leFH 18M was mounted on a towed chassis, with large metal or wooden wheels rimmed with rubber. Initially, it was fitted with a single-baffle muzzle brake of relatively low efficiency. This was later improved by welding two protruding ears to the rear of the port. However this style of muzzle brake proved troublesome with the early designs of fin-stabilized and discarding-sabot shells and a new cage-type muzzle brake was designed and fitted.
The new FH Gr Fern long-range shell was about 25 mm longer than the normal 105mm shells used by the leFH 18 guns, but had a shorter streamlined section behind the driving band to accommodate the larger powder charge required. This fit in the standard cartridge case, but protruded about 50mm past its mouth.
Ballistically, the 10.5 cm leFH 18M and the leFH 18/40 are identical.
