[1] All modern 1301 shotguns, much like their A400 counterparts, make use of a Beretta proprietary choke constriction system known as "Optimachoke-HP".

Main improvements from the Tx4 Storm includes an enlarged polymer charging handle and an oversized bolt release lever, which doubles as a magazine ejection button when pressed on the rear side or lifted up from the front.

[3] The 1301 Tactical currently has three factory colors: Black, Flat Dark Earth, and Olive Green Drab.

A fourth color, Marine, was previously available but discontinued due to the weaker silver finish wearing off quickly.

The polymer top rail was changed to aluminum to improve its durability and precision when heavier optics are mounted.

It features an updated forend with M-Lok slots found on the A300 Ultima Patrol, a semi-flat competition trigger, and the Pro Elevator, which automatically moves the shell lifter up once the bolt closes, greatly improving the reloading experience.

This enables competition shooters and gunsmiths to enlarge the loading port beyond the factory opening without defacing the serials.

Similar to the clay pigeon shooting focused A400 Xcel, the 1301 Comp Pro features a distinct, blue finish on the receiver.

The shooter no longer needs to hold the lifter open to reload the tube, drastically improving ergonomics.

Another major upgrade is a new polymer stock with the Kick-Off Plus system previously found on Beretta's A400 lineup.

The recoil absorption point is in front of the cheek weld, moving in unison with the forearm.
