A gun attachment adapted to fit to the subframe of a handgun and mount to a laterally extending member which can be a modified laterally extending member to extend beyond the lateral surfaces of the subframe, whereby an extension member which moves with respect to a base member applies a force to the trigger guard of the subframe, thereby creating a positive torque counteracted by engagement of a chamber region to the forward portion of the subframe whereby the gun attachment is rigidly attached to the subframe of the handgun without substantially modifying the same. The handgun attachment further comprises a forward member adapted to have load exerted thereon and transferring the load to the subframe and not to the slide, thereby maintaining the handgun in battery and allowing the handgun to be fired in a close quarter situation.
