Best 20-Gauge Shotguns 2026: Hunting, Youth & Defense

Pick the action first, then check that the stock fits, then look at the choke system. Those three decisions account for almost everything that separates the seven guns above, and price is mostly a consequence of them rather than a fourth axis. A 20 gauge semi auto shotgun costs more than a single shot because it carries a working action, and an over/under costs more again because it carries two barrels regulated to shoot together.

A semi-auto is the default for repeat shots. The Franchi Affinity 3 uses an inertia-driven action, which means there is no gas system in the operating cycle; the Beretta A300 Ultima Patrol 20 Gauge uses a gas action and is built around defense rather than the field. A 20 gauge pump shotgun trades cycling speed for the lowest price of any repeater here: the Winchester SXP Black Shadow holds five 2.75-inch shells and ships with three chokes, and a manual stroke between shots is slower than either semi-auto. If you want the same decision made across the full pump market, our best pump shotgun guide runs that comparison.

A 20 gauge over under shotgun gives up capacity to buy two independent constrictions. Each barrel takes its own choke tube, so a first shot can go out of an open tube and the second out of a tighter one without touching the gun. The Browning Citori 825 Field Sub-Gauge spends its price on a low-profile steel receiver, Grade II/III walnut, and the Fire Lite 2 mechanical trigger, which fires the second barrel on its own sear rather than waiting on recoil. The TriStar Setter S/T spends far less and hands you five Mobil-pattern tubes from skeet to full. If the choke vocabulary is new, read shotgun chokes explained before you buy tubes for either gun.

Single shots are the cheapest and simplest, and both here have a specific job. The Henry H15 Youth exists for a 13-inch length of pull. The Stevens 301 Turkey exists for the extra-full choke and the optics rail. Neither is a general-purpose gun, because every follow-up shot means a full reload.

The best 20 gauge youth shotgun in this ranking is the Henry H15 Steel Single Shot Youth at $479.67, because its 13-inch length of pull is the shortest fixed stock in this ranking, more than an inch under the adult field stocks on the Franchi and both over/unders. That number is the whole reason the category exists. A shooter who cannot reach the trigger without stretching cannot mount the gun the same way twice, and no amount of practice fixes a stock that is too long.

Compare the measurements directly. The Henry is 13 inches. The Stevens 301 Turkey is 13.8 inches, shorter than an adult field gun but not a true youth length. The Franchi Affinity 3 is fixed at 14 3/8 inches, and both the Browning Citori 825 and the TriStar Setter S/T are fixed at 14 1/4 inches. The Beretta A300 Ultima Patrol 20 Gauge is the only pick that moves, adjusting from a 13-inch length of pull down to 12 inches.

The Henry buys more than fit. Its one-round break action makes loading and chamber status easy to inspect, which matters when a new shooter is being supervised. The steel receiver is drilled and tapped for a Weaver 82 base if the gun later becomes a slug-and-optic setup, and the Rem-style choke threads ship with a removable Modified tube. The honest limits are that a follow-up shot means a full reload, and the 40.5-inch overall length is not especially compact despite the short stock.

The 20 gauge turkey shotgun that needs the least work out of the box is the Stevens 301 Turkey 20 Gauge Obsession at $299, because the two parts most turkey hunters buy separately are already on it. The extra-full WinChoke-pattern tube is the constriction a turkey load wants, and the removable one-piece optics rail means a red dot mounts without drilling the receiver. A six-pound gun with sling studs and a Mossy Oak Obsession stock is built for carrying to a setup and sitting still.

The trade is real: one round, then a complete reload. A turkey hunter who wants a second shot available should be looking at the Winchester SXP Black Shadow, which holds five 2.75-inch shells and takes Invector-Plus tubes, or at a semi-auto. For a wider field of dedicated turkey configurations across gauges and actions, our best turkey shotgun guide covers the 12-gauge and .410 options alongside 20.

The 20 gauge tactical shotgun pick is the Beretta A300 Ultima Patrol 20 Gauge at $1,199, and it is the only gun in this ranking configured for defense rather than adapted to it. Seven plus one with 2.75-inch shells leads the group by two rounds over the Winchester SXP and by six over either single shot. The 19.1-inch barrel keeps the gun short indoors, and ghost-ring sights come on it from the factory.

Mounting is where it separates itself. A seven-slot Picatinny rail and three M-LOK points are already on the gun, so a red dot and a light go on without a gunsmith. The Franchi Affinity 3 is drilled and tapped but installs no base at the factory; the Winchester SXP has a brass bead and no rail at all. The stock adjusts from a 13-inch length of pull down to 12 inches, and the oversized loading port, bolt handle, bolt release, and reversible safety are the controls that make the gun workable under stress.

The same features that make it a defensive gun make it a poor field gun. That short stock feels cramped for a shooter who wants an adult field-gun fit, and a 19.1-inch barrel with ghost rings is not a wing-shooting setup. If you want the full defensive shotgun field rather than the 20-gauge slice of it, compare layouts in our best home defense shotgun guide and the gas-versus-inertia breakdown in the best tactical semi-auto shotgun guide.

Gauge alone does not give you a power comparison. Gauge describes bore diameter, not the payload or the velocity of the shell you load into it, and the result on target depends on the gun, the load, the pattern, the range, and what you are shooting at. Compare the exact shell's payload and velocity, then pattern that load through the exact barrel and choke you plan to use.

The same reasoning applies to recoil, which is the usual reason people move to 20 gauge in the first place. Gun weight, action type, stock fit, and payload all change how a shot feels, and the spread here shows it: the Beretta A300 Ultima Patrol runs a gas action, the Franchi Affinity 3 runs an inertia action, both over/unders are break actions with no operating cycle at all, and weights across the ranking sit close together. A 20 gauge that fits you will feel better than a 12 gauge that does not, and a 20 gauge that does not fit will not feel better than anything.

Practically, that means fit and choke selection do more for a buyer than gauge arguments. The Franchi's five shims and the Beretta's adjustable stock are the two fit adjustments available in this ranking; everything else is fixed and needs to fit you as it comes. Once the gun fits, the choke does the rest of the work, which is why the TriStar Setter S/T's five tubes and the Stevens 301's extra-full tube are worth more than they look on a spec sheet. Use the shotgun builder to see which optics, lights, and mounts actually fit the receiver and rail on the gun you pick.
