Best 3-Gun Shotguns for 2026: Competition Semi-Autos Ranked

Last updated May 2026 · By Nick Hall, multigun competitor

The Benelli M2 is the best 3-Gun shotgun for serious competitors, the long-reigning king of the sport with the deepest aftermarket and the fastest reloads, but the Mossberg 940 JM Pro is the best value, running light loads reliably with competition controls for several hundred dollars less. A 3-Gun shotgun is a different animal from a clay gun: you need a big loading port, a smooth tube you can quad-load, light-load reliability, and a semi-auto action that cycles fast. This guide ranks eight, with pros and cons, live prices, and the setup and rules that decide which one wins.

The shotgun is the leg of 3-Gun that humbles people, because it is the only gun you reload constantly under the clock, and a slow, fumbling reload costs you more time than any miss with a rifle or pistol. That makes a 3-Gun shotgun a very specific tool: it is built around loading speed, not patterning a clay target. A wide, beveled loading port, a smooth magazine tube, light-load reliability, and a fast semi-auto action matter far more than the choke selection that defines a clay gun. This is a different job from the clay sports, which my best shotguns for clay shooting roundup covers. New to the sport? Read what 3-Gun shooting is first.

Prices move with the market. The single biggest dividing line is the action: inertia guns like the Benelli are simple, light, and run dirty, while gas guns like the Mossberg 940 and Beretta 1301 shoot softer and run light target loads more reliably. I cover that trade-off, the loading-port question, and how to set one up after the picks.

1. Benelli M2: Best Overall 3-Gun Shotgun

The Benelli M2 has been the king of competition shotguns for so long that it is the default answer when anyone asks what the pros run. Its inertia-driven action is utterly reliable, the gun is light and fast-handling, and crucially it has the deepest aftermarket of any shotgun, so every competition part you could want, oversized bolt handles and releases, lifted and beveled loading ports, magazine extensions, speed loaders, already exists for it. A Taran Tactical or Briley-tuned M2 is the gold standard of a 3-Gun shotgun.

The catch is cost. The M2 starts higher than the value guns at around 1,150 dollars, and a full competition build with a ported barrel, extended tube, and a worked loading port climbs well past that. Its inertia action also runs the very lightest target loads a little less reliably than a tuned gas gun, though it is still good. But for a committed competitor who wants the platform with the most support and the most wins, the M2 is the benchmark.

2. Mossberg 940 JM Pro: Best Value 3-Gun Shotgun

The Mossberg 940 JM Pro is the gun that changed the value equation, developed with multigun legend Jerry Miculek and tuned to his standards rather than just wearing his name. The thing that sets it apart at this price is light-load reliability: the gas system was specifically tuned to run the soft target loads that choke most affordable gas guns, which is exactly what a 3-Gun shooter feeds it. It also ships with competition controls out of the box, an enlarged loading port, an oversized bolt handle and release, and a fiber-optic sight.

At around 750 dollars it undercuts a Benelli M2 by several hundred dollars while arriving closer to match-ready, which is why it has flooded club 3-Gun. It is a gas gun, so it is a touch heavier and needs cleaning more often than an inertia gun, but the value and the factory competition features make it the smartest first 3-Gun shotgun. See it at Mossberg.

3. Beretta 1301 Comp: Best Gas-Gun Speed

The Beretta 1301 is the fastest-cycling gas gun in the game, thanks to Beretta’s Blink gas system that the company claims cycles dramatically faster than rivals, and on the clock you feel it. It shoots exceptionally soft and flat, runs light loads beautifully, and the Comp version adds the competition features a 3-Gun shooter wants. For a shooter who prioritizes the softest, fastest-cycling action over the M2’s aftermarket, the 1301 is the pick.

At around 1,475 dollars it is the priciest gun here and the aftermarket, while growing fast, is not as deep as the Benelli’s. But the raw speed and soft shooting of the Blink system have made the 1301 a serious challenger to the M2 at the top of the sport, and many top shooters have switched to it. See it at Beretta.

4. Beretta A300 Ultima Patrol: Best Budget Gas Gun

The Beretta A300 Ultima brings much of the 1301’s gas-gun pedigree to a lower price, around 850 dollars, and the Patrol version adds a usable loading port, an extended magazine, and ghost-ring or fiber sights. It runs the soft target loads well, shoots smoothly, and carries Beretta’s reputation for reliability, making it a strong value bridge between the budget guns and the premium 1301.

It is heavier than the 1301 and the action is not quite as fast, and the loading port still benefits from opening up for serious quad-loading. But for a shooter who wants a Beretta gas gun and competition features without the 1301 price, the A300 Ultima Patrol is an excellent middle-tier choice that punches above its cost.

5. Winchester SX4: Best Entry Semi-Auto

The Winchester SX4 is the value benchmark for an entry 3-Gun semi-auto, a reliable gas gun at around 620 dollars with a large loading port and a 3-inch chamber that handles the range of loads a stage throws at you. It is a proven, no-drama platform that gets a new shooter on the line affordably, and the controls are large enough to run reasonably fast out of the box.

It is not as tuned for the lightest competition loads as a Mossberg 940 JM Pro and the aftermarket is thinner, so it is more a starting point than a podium gun. But as the cheapest reliable gas semi-auto that will run a 3-Gun stage, the SX4 is a smart way to try the sport before committing to a dedicated competition shotgun.

6. Stoeger M3000: Best Budget Inertia Gun

The Stoeger M3000 is the budget inertia option, built under the Benelli umbrella and sharing the same reliable inertia-driven action for around 400 dollars. That Benelli DNA means it runs clean and reliable, and because it shares the action design, some Benelli-pattern parts and a healthy budget aftermarket let you add a loading-port bevel and a magazine extension to build a real entry 3-Gun gun cheaply.

It is more basic than a true M2, the lightest loads can be marginal as with any inertia gun, and the fit and finish are budget-grade. But for a shooter who wants the reliable inertia action and a path to a competition build at the lowest possible price, the M3000 is the value play, and many shooters run lightly-modified ones at club matches.

7. Franchi Affinity 3: Best Lightweight Inertia Gun

The Franchi Affinity 3, also a Benelli-family inertia gun, is the lightweight pick, a reliable, well-balanced semi-auto at around 700 dollars that handles fast and runs clean. Its inertia action is dependable, the gun points naturally, and the Sporting and competition-oriented versions add a longer barrel and better sights, making it a comfortable, fast-handling 3-Gun option for a shooter who values light weight.

Like all inertia guns it can be a little finicky with the very lightest loads, and the loading port benefits from opening up for serious quad-loading. But the Affinity 3 is reliable, affordable, and handles beautifully, and it is a strong mid-tier choice for a shooter who wants a light inertia gun without the Benelli M2 price.

8. Retay Gordion: Best Sleeper Value

The Retay Gordion is the sleeper of the group, a Turkish-made inertia gun that has earned a strong reputation for quality well above its roughly 615 dollar price. It uses an inertia action with a clever bolt-release feature, runs reliably, and the fit and finish embarrass guns costing more, which has made it a quiet favorite among value-minded shooters who have discovered it.

As a less mainstream brand the aftermarket is thinner and resale is less certain than a Benelli or Beretta, and the lightest loads carry the usual inertia caveat. But for a shooter willing to look past the big names, the Gordion delivers genuine quality and reliability at a price that makes it one of the best values in a 3-Gun-capable semi-auto.

Best 3-Gun Shotgun by Use Case

Sorted by what you actually need, here is how these guns stack up.

• Best overall: Benelli M2, the proven king with the deepest aftermarket.
• Best value: Mossberg 940 JM Pro, factory competition features and light-load reliability.
• Best gas-gun speed: Beretta 1301 Comp.
• Best budget gas gun: Beretta A300 Ultima Patrol or Winchester SX4.
• Best budget inertia: Stoeger M3000.
• Best lightweight: Franchi Affinity 3.
• Best sleeper value: Retay Gordion.

Inertia vs Gas: Which Action for 3-Gun?

The biggest decision in a 3-Gun shotgun is the action type, and it shapes how the gun shoots and how it runs. The two systems each have a real case.

• Inertia guns, such as the Benelli M2, Stoeger, Franchi and Retay, use the recoil-driven inertia of the bolt to cycle. They are simpler, lighter, and run a long match without cleaning because they stay clean, since gas and fouling do not blow back into the action. The trade-off is more felt recoil and slightly less reliability with the very lightest target loads, which a 3-Gun shooter often uses to save money and recoil.
• Gas guns, such as the Mossberg 940, Beretta 1301 and A300, and Winchester SX4, tap gas to cycle, which makes them shoot noticeably softer and flatter and run the lightest loads more reliably. The trade-off is more weight, more cleaning, and a more complex action. For 3-Gun specifically, the soft recoil and light-load reliability of a tuned gas gun like the 940 JM Pro or 1301 are real advantages.

For 3-Gun, the case for a gas gun has grown stronger as the Mossberg 940 JM Pro and Beretta 1301 have shown how soft and reliable a tuned gas action can be. The Benelli M2 inertia gun still wins on aftermarket and simplicity. Either can win matches; it comes down to whether you value the soft recoil of gas or the simplicity and parts support of inertia.

The Loading Port and Reloads: Where Matches Are Won

If you remember one thing about 3-Gun shotguns, make it this: the shotgun is won and lost on the reload. You will reload the shotgun constantly during a stage, and the difference between a smooth quad-load and a fumbling one-at-a-time reload is enormous over a match. That is why competition shotguns and competition modifications focus so heavily on the loading port and the magazine tube.

• A wide, beveled loading port. The single most important competition modification. Opening up and beveling the loading port lets you push two or four shells in at once, which is the foundation of every fast reload technique.
• A smooth, polished magazine tube. Shells need to slide in without catching. Many competition guns and gunsmiths polish the tube and follower for friction-free loading.
• A magazine extension. 3-Gun stages reward capacity, so an extended tube that holds eight or more rounds reduces how often you reload, within your division’s rules.
• An oversized bolt handle and release. Large controls you can hit fast under stress, standard on guns like the 940 JM Pro and a common upgrade on others.

This is exactly why the Mossberg 940 JM Pro and a tuned Benelli M2 dominate: they come with, or are built around, a competition-ready loading port. A cheaper gun with a worked port will out-run a more expensive gun with a tight factory port, so prioritize the port over almost everything else.

How to Set Up a 3-Gun Shotgun

Beyond the gun itself, a few additions turn any quality semi-auto into a competitive 3-Gun shotgun.

• Open and bevel the loading port if it is not already, the highest-value modification by far.
• Add a magazine extension for capacity, sized to your division rules, and a polished tube and follower for smooth loading.
• Oversized controls. A larger bolt handle and bolt release you can hit fast under stress.
• A fiber-optic front sight for fast target acquisition on close, fast clay and steel arrays.
• Practice the quad-load. The gear only helps if you drill loading two or four shells at a time until it is automatic, which is the single most valuable shotgun skill in 3-Gun.

3-Gun Shotgun Rules to Know

Before you build, know that the divisions shape what is legal. Most 3-Gun divisions limit the shotgun to a tube magazine fed by hand, no detachable box magazines or speed-loaders during the stage in the more restrictive divisions like Limited and Heavy Metal, so hand-loading speed is everything. Open division allows the most, including detachable magazines on some guns and the longest tube extensions. Heavy Metal requires a 12-gauge pump with iron sights and no porting, the hard-mode throwback. Confirm your division’s rules on magazine capacity, porting, and optics before you spend on modifications, and read what 3-Gun shooting is for the full division breakdown.

The Bottom Line

For a serious competitor who wants the best, the Benelli M2 is the proven king with the deepest aftermarket, though a tuned Beretta 1301 now challenges it on soft, fast cycling. For value, nothing beats the Mossberg 940 JM Pro, with factory competition features and the light-load reliability 3-Gun demands. Starting out or on a budget, a Winchester SX4 or Stoeger M3000 gets you on the line. Whatever you pick, prioritize the loading port, add a tube extension, and drill your quad-load, because the shotgun is won on the reload far more than the gun. New to it all?
