Abstract
The powder actuated door lock-forcing tool has a modular construction which comprises: a pistol grip module; and a barrel assembly module. The barrel assembly module is readily detachable from the pistol grip module to allow interchangeability of different barrel assemblies which are specifically adapted to disrupt different types of door locks. The barrel assembly module includes a piston carried in a barrel, which piston is configured to be driven beyond the muzzleward end of the tool sufficiently to disable or disrupt a lock at which the tool is fired. The piston may have a cylindrical configuration or a flattened oval configuration at its muzzleward end.
