Indumil was originally known as National Workshop of Mechanic Crafts (Spanish: Taller Nacional de Artes Mecánicas).

Its first factory, named General José María Córdova, was intended to produce small arms and ammunition.

Through a staged process Indumil developed licensed production of IMI Galil rifles for the use of the Colombian military.

It is a 6 to 10 shot capacity, caliber .38 Special revolver, which is produced mainly at the General José María Córdova factory.

Indumil is one of two companies that produce the IMI Galil rifles outside Israel, the other being Denel of South Africa.
