Firearm with interface modules for firearms

1. Firearm comprising:

a handle piece,

a firearm control means integrated into the firearm, and

an interface accessible from an exterior of the handle piece for an electrical connection to a replaceable firearm module and for transmission of information and energy between the firearm control means and the firearm module, wherein

the interface is arranged on a side of the handle piece between a trigger guard of the firearm and a muzzle of the firearm,

the firearm module is adapted to be releasably connected to the interface by coupling the firearm module to the handle piece in an area between the trigger guard and the muzzle, and

wherein the firearm module includes at least one device selected from the group consisting of a device for determining the position of the firearm, a device for detecting DNA, and a device for detecting voice or speech signals.

2. A firearm comprising a firearm module for a firearm, wherein the firearm module is releasably connectable via a firearm contact interface of the firearm that is accessible and arranged on a side of a barrel between a trigger guard of the firearm and a muzzle of the firearm, said firearm contact interface is adapted for transmission of information between a firearm control means of the firearm and the firearm module,

wherein the firearm module is adapted to be mechanically and electrically connected to the firearm contact interface by coupling the firearm module to the firearm in an area between the trigger guard of the firearm and the muzzle of the firearm such that the firearm module and the firearm contact interface releasably touch each other, and

wherein the firearm module includes at least one device selected from the group consisting of a device for determining the position of the firearm, a device for detecting DNA, which can be transmitted in a wireless manner, and a device for detecting voice or speech signals.
