The invention relates to an ammunition supply indicator device that can be incorporated into a firearm (11), said firearm (11) comprising a magazine (21) including movable means (22, 23) that slide along a longitudinal axial direction of the magazine (21). The device (12) includes a predetermined number of means (41) for receiving a magnetic field generated by actuator means (24) connected to the above-mentioned movable means (22, 23), whereby the level of the electric signal is dependent on the relative distribution of the receiving means (31) in relation to the magazine (21), the type of material used to produce the firearm (11), the magazine (21), and the position of the movable means (22, 23).
