The breaching shotgun is a specially modified, pump action shotgun designed to breach locked doors. The weapon fires frangible breaching ammo that is designed to quickly break into very small pieces upon impact. This behavior reduces penetration and increases damage upon impact with hard surfaces. These factors make it ideal for breaking locks on doors without penetrating the door and harming someone on the other side. The toothed extender on barrel allows officers to jam the weapon into the door and ensures the correct distance from the lock for the breaching ammo to be most effective. Its compact design permits officers to carry the weapon on their back, allowing it to be carried in addition to the primary weapon.
