The Beretta Tx4 Storm represents yet another solution in Beretta's line of home-defense options. The shotgun incorporates decades of Beretta's experience perfecting the gas operated semi-automatic design. Weighing under 6 1/2 pounds, the compact Tx4 Storm shotgun, with its 18-inch barrel, is very maneuverable, while maintaining a 5+1 round capacity. Like the Cx4, the shotgun's length of pull may be adjusted with 1/2-inch spacers (one included), while the soft rubber grip inlays on the stock and fore-end ensure a firm grip in all situations. A metal Picatinny rail is mounted to the receiver to accept a variety of optics or the included rugged and fully adjustable ghost ring sight. Adopting Beretta's Optimabore HP choke tube system, the included choke may be replaced with several optional accessories. Like the rest of the Storm family (Px4 Storm pistols and Cx4 Storm carbines), the Tx4 may be accessorized to meet the demanding needs of today's shooter.
