## Abstract

A weapon system includes a long gun, such as a rifle or a shotgun, a handgun, and a bracket secured to the rifle or shotgun around the barrel. The bracket permits swiveling and firing the handgun while attached to the long gun. The bracket includes a swivel ball joint below the long-gun barrel and an attachment brace that releasably connects the swivel ball joint and the handgun. The handgun may be a semi-automatic pistol where a slide moves back and forth when fired. The attachment brace has a top section and a bottom section. The top section goes around the slide so that it does not interfere with its movement. The bottom section contacts the handgun below the slide to securely attach the handgun to the rifle or shotgun.

## Claims

### Claim 1

A weapon system comprising:
a long gun, the long gun comprising a long-gun barrel;
a handgun, the handgun comprising a pistol grip and a muzzle; and
a bracket secured to the long gun around the barrel, the bracket comprising:
a swivel ball joint below the long-gun barrel; and
an attachment brace releasably connecting the swivel ball joint and the handgun, the attachment brace tighten-able to the handgun such that the muzzle of the handgun is configured to be adjusted to a rotatable position in three dimensions, and such that the handgun can be fired when in such rotatable position while connected to the swivel ball joint.

### Claim 2 (depends on 1)

The weapon system of claim 1, wherein the handgun is a semi-automatic pistol; wherein the handgun further comprises a slide; wherein the attachment brace is constructed with a top section and a bottom section; wherein the bottom section contacts the handgun below the slide; and wherein the top section is not in contact with the handgun and permits unimpeded movement of the slide.

### Claim 3 (depends on 1)

The weapon system of claim 1, further comprising a finger-operable set screw that when tightened engages the swivel ball joint to add frictional resistance to rotation of the swivel ball joint.

### Claim 4 (depends on 1)

The weapon system of claim 1, further comprising a telescoping rod connecting the swivel ball joint to the attachment brace.
