LMG-25: The Swiss Toggle-Locked Light Machine Gun

The LMG-25 was designed by Adolph Furrer at Waffenfabrik Bern in the 1920s. Furrer was a devoted fan of the toggle locking system, and also designed a toggle-locked submachine gun that Switzerland (unwisely) adopted in 1941. The LMG-25 was first produced in 1924, adopted in 1925, and remained in production until 1946 with a total of 23,045 standard models and 1,742 optics-equipped fortress models made.

It is chambered for the standard 7.5x55mm Swiss cartridge with a 30-round side-mounted magazine (interchangeable with the later Stgw 57 magazine, incidentally). It is an effective design, if expensive to produce, and served Switzerland well for several decades.
