Best Beretta 1301 Upgrades 2026: Magazine Tubes, Optics, Mounts & More (Nordic, Aridus, Mesa Tactical)

The Beretta 1301 Tactical is an outstanding defensive shotgun out of the box. The BLINK gas system cycles faster than any competing semi-auto action, recoil is manageable for rapid follow-up shots, and the Mod.2 comes factory-ready for optics and accessories. So why spend more?

Because the factory configuration leaves practical capability on the table. The 5+1 magazine capacity is adequate but not optimal. There is no weapon light included. The factory stock is fixed and does not accommodate plate carriers or allow length-of-pull adjustment. And while the factory Picatinny rail accepts optics, the right mount choice significantly affects sight height and co-witness capability. Each upgrade in this guide addresses a real limitation without altering the BLINK gas system or bolt assembly that make the 1301 reliable.

The 1301's growing aftermarket means you can now build a fully kitted defensive shotgun that rivals a Benelli M4 setup at significantly lower total cost. A fully upgraded 1301 runs approximately $2,300-$2,500 total, versus $3,000+ for an equivalent M4 build. For a detailed comparison of shotgun platforms, see our best tactical semi-auto shotgun guide for gas-op vs inertia picks, or the best home defense shotgun guide for pump-action options.

The Beretta 1301's BLINK gas system is what sets it apart. BLINK is a short-stroke gas-operated action that Beretta claims cycles 36% faster than competing semi-auto shotguns. The system uses a simplified bolt group with a cross-bolt locking mechanism, reducing the number of moving parts compared to traditional gas-operated designs. The practical result is fast cycling with noticeably less felt recoil than the Benelli M4's ARGO system.

The Mod.2 update brought the 1301 into modern defensive shotgun standards. It added an M-LOK compatible forend for direct accessory mounting, a factory Picatinny top rail for optics, enlarged controls for stress shooting, and an 18.5-inch barrel optimized for defensive use. These factory improvements mean the Mod.2 needs fewer aftermarket parts than its Gen 1 predecessor to reach a fully capable defensive configuration.

The 1301 aftermarket has grown significantly since 2020. Companies like Aridus Industries, Nordic Components, GG&G, and Mesa Tactical now produce purpose-built 1301 accessories that rival the Benelli M4's aftermarket depth. The Aridus CROM mount, in particular, defined the 1301 aftermarket when it launched and remains one of the most popular optic mounting solutions for the platform.

If you already own a 1301 or an M4, upgrade what you have. If you are deciding between buying one to build up, the calculus is straightforward. The 1301 Tactical costs $600-$700 less than the M4 at retail. A fully upgraded 1301 totals roughly $2,300, versus $3,200+ for an equivalent M4 build. The M4 has a more extensive aftermarket and proven military pedigree. The 1301 cycles faster and recoils less. For home defense, the 1301 is the better value proposition. For duty or hard-use where the M4's military track record matters, see our Benelli M4 upgrades guide.

Why capacity comes first: The factory Beretta 1301 ships with a 4+1 capacity limited by the magazine cutoff for sporting import compliance. The 1301 tube threads accept extensions from several manufacturers without modification to the action or gas system, and adding two to four shells changes the tactical and competitive calculus of the shotgun entirely. This is the highest-priority upgrade on the 1301 before any other modification touches the gun.

Extension options by use case: Nordic Components makes a two-shot extension that brings the 1301 Tactical to 6+1, and a four-shot extension that reaches 8+1 with standard 2.75-inch shells. GG&G also makes 1301-specific tube extensions with a reputation for consistent threading tolerances. For three-gun competition, the four-shot extension is the standard; for home defense in restricted jurisdictions, verify local magazine capacity laws before ordering. All extensions thread onto the factory tube; no drilling or permanent modification required.

Shell storage on the gun: A receiver-mounted side saddle gives you six immediately accessible shells for a fast in-battery reload. Aridus Industries and Mesa Tactical both make 1301-specific aluminum side saddles that bolt to the receiver without permanent modification. For extended operations or competition stages, a belt-mounted shell carrier or chest rig keeps a second reload wave within reach. Running a tube extension and a side saddle together is the standard 1301 competition and home defense setup.
