The Tx4 is part of Beretta's Storm line of defensive weapons, a lightweight, gas-operated semi-automatic shotgun based off the A400 line of hunting shotguns. The TX4's small size makes it very maneuverable, even in the close quarters of a home. The stock and forend are black polymer with rubber inlays in the grip surfaces, providing a solid grip on the weapon. The trigger group is polymer as well, with a cross-bolt safety at an excellent position to flick off with the trigger finger when it is indexed along the trigger guard. Beretta's Blink system utilizes a self-adjusting exhaust valve, allowing it to cycle all types of loads, from low power birdshot, to high pressure buckshot loads without adjustment, replacement of pistons, or damage to the action. 3-dot ghost rings sights provide shooters with a clear, quickly realized sighting picture. This shotgun's stock and metal are in good condition and its bore is in very good condition.
