Description

M3/M3A1 Submachine Gun Magazine Loader.

This is a fast loader for the M3 and the, in 1944 improved, M3A1 machine gun magazines.
The M3 was also called Grease gun.
Due to the stiff spring tension of the 30 rounds magazine a loader was required.
With the arrival of the updated M3A1, the magazine loader was also introduced.
