The Beretta 1301 Tactical has become the darling of the defensive-shotgun world, and for good reason: its BLINK gas system cycles about 36% faster than the competition, making it one of the softest-shooting, fastest-running semi-auto shotguns you can buy. The newest version already ships with an oversized charging handle, an enlarged bolt release, a big reversible safety, ghost-ring sights, and a receiver rail — so a 1301 build is about capacity, an optic, and a few premium touches rather than fixing the basics.
Below are the Beretta 1301 parts and accessories we would add first. Like the Benelli M4, the 1301’s aftermarket is specialized, so these are the proven pieces serious owners actually run. Everything here fits the 12-gauge 1301 Tactical (confirm your exact configuration), and each pick is backed by a live price check across the retailers we track.
How we tested: Every pick here was run through our testing methodology. Minimum round counts, accuracy and reliability protocols, the failures that disqualify a gun. If we haven't shot it, we don't recommend it.

Best Magazine Extension: Nordic Components
Capacity is the 1301’s most-wanted upgrade. Depending on your model and local laws, a Nordic Components extension raises the magazine tube to seven or more rounds, which matters on a defensive shotgun. Nordic’s tubes are machined to work with the fast-cycling BLINK system without inducing feeding problems. Match the tube length to your barrel and confirm your local capacity limits.
Best Red Dot Optic: Holosun 507C
The 1301 wears a receiver rail, and the optics-ready Mod 2 models make mounting a dot even cleaner. A shotgun-rated red dot like the Holosun 507C transforms the 1301 into a fast, both-eyes-open fighting gun, which is exactly where its soft, quick cycling shines. Confirm your rail or optic cut and footprint, choose a recoil-rated dot, and co-witness it with the factory ghost rings for a backup.
Best Stock: Mesa Tactical Urbino
The factory stock is good, but the Mesa Tactical Urbino is the upgrade competition and defensive shooters reach for: a shorter, fixed length of pull with an optional adjustable cheek riser gives you a faster, more consistent mount, especially behind a red dot. It is the stock that most improves how the 1301 comes to the shoulder.
Best Shell Carrier: Mesa Tactical SureShell
A shotgun holds few rounds, so keeping spares on the gun is essential. The Mesa Tactical SureShell side saddle mounts to the 1301’s receiver and carries extra shells within instant reach for reloads, and many versions integrate an optic rail. It is the durability-and-retention standard for shell carriers on the platform.
Best Light Mount: GG&G Rail Mount
A light is non-negotiable on a defensive shotgun. A GG&G rail mount made for the 1301 clamps to the magazine tube and holds a standard weapon light exactly where your support hand can reach the switch. Add a bright, recoil-rated light and you have a complete low-light package on one of the fastest-handling shotguns made.
Best Follower: GG&G High-Visibility
A bright-colored follower is a small, smart upgrade that lets you see at a glance when the magazine is empty — useful in low light and during fast strings of fire. The GG&G high-visibility follower for the 1301 drops in easily and pairs naturally with a magazine-extension install. It is a few dollars for a genuine quality-of-life improvement.
Best Bolt Release: Beretta Enlarged Kit
The newest 1301 already has an enlarged bolt release, but earlier guns benefit hugely from Beretta’s enlarged bolt-release shroud kit, which makes the small factory button far easier to hit under stress. If your 1301 predates the oversized control, this is the upgrade that most improves how you run the gun. Check which your model has before buying.
Best Choke Tube: Carlson’s OptimaBore HP
The 1301 uses Beretta’s OptimaBore HP choke system, and the right tube tunes the gun for the job. A Carlson’s OptimaBore HP choke lets you tighten buckshot patterns for defense or open things up for other loads, wringing more consistency out of every shell. It is a cheap way to meaningfully change how the gun patterns downrange.
How to Prioritize Your Beretta 1301 Build
The 1301 is superb out of the box, so upgrade to tailor it rather than fix it:
- A magazine extension and a light first. Capacity and target identification are the two things a defensive shotgun needs most.
- A red dot — the 1301’s fast handling is made for a dot.
- A stock that fits you and a shell carrier for spare rounds on the gun.
- The small touches — high-vis follower, bolt release (on older guns), and the right choke — to finish the build.

Frequently Asked Questions
What is the best upgrade for a Beretta 1301?
The 1301 is excellent from the factory, so the highest-value upgrades are a magazine extension for capacity and a light for target identification, followed by a red dot to take advantage of the gun's fast handling. Because the newest 1301 already has oversized controls and ghost-ring sights, a build is about tailoring the gun rather than fixing shortcomings.
How many rounds does a Beretta 1301 hold with an extension?
The current 1301 Tactical ships with a 7+1 one-piece magazine tube, while earlier guns held 5+1. Depending on your model and local laws, a magazine extension can raise capacity to eight or more rounds. Match the tube length to your barrel and confirm your local capacity limits before buying.
Is the Beretta 1301 optics ready?
The 1301 Tactical has a factory receiver rail, and the newer Mod 2 optics-ready models add a milled optic cut for a lower dot mount. Either way you can run a shotgun-rated red dot such as a Holosun 507C; just confirm your specific rail or cut and the optic footprint before buying, and co-witness with the ghost-ring sights.
Do you need a gunsmith to upgrade a Beretta 1301?
Most 1301 upgrades are owner-installable: magazine extensions, stocks, followers, shell carriers, light mounts, bolt-release kits, and choke tubes all install at home with basic tools. The BLINK gas system needs no tuning for standard loads, which keeps upgrades simple.
What choke does a Beretta 1301 use?
The 1301 uses Beretta's OptimaBore HP (Optima-Choke HP) system and ships with an Improved Cylinder tube. Aftermarket OptimaBore HP chokes from makers like Carlson's let you tune patterns for buckshot, slugs, or other loads. Always confirm a choke is listed for the OptimaBore HP pattern, not the older Mobil pattern.
