A gun having a wedge-type breech block and a barrel that is seated in a cradle for firing electrically-ignitable cartridges that contain electronic components, and in which an ignition contact (4) is disposed on the cartridge base or bottom (3) for producing a connection to an external current source, and a signal contact (5) is disposed on the cartridge base for connecting the electronic components to an external electronic control and evaluation device. To ensure the simple and reliable ignition of the cartridge, as well as the transmission of data from the cartridge to an external unit, an axially displaceable ignition and signal-transmission unit (8) is provided in the breech block. The unit includes a housing (11) having two parallel, axial guides (12, 13), with two spring-loaded, needle-shaped contact devices (16, 17) being arranged to be displaced inside the respective guides such that, in the extended position of the ignition and signal-transmission unit (8), the first contact device (16) is pressed against the ignition contact (4) and the second contact device (17) is pressed against the signal contact (5) of the cartridge. The two needle-shaped contact devices (16, 17) are supported by respective compression spring (14, 15) against the housing (11) of the ignition and signal-transmission unit (8), so that the two contact devices (16, 17) can execute a different equalization stroke in the extended position of the ignition and signal-transmission unit.
