The shotgun decision is mostly an ammunition decision

Here is what a 12 gauge actually costs to feed right now, across every retailer we track:

We have 1,875 live 12 gauge listings as this publishes. The market floor sits near 36 cents a shell, the catalog average runs near a dollar, and the top of the range clears $17 per round for specialty hunting loads. No other common chambering has a spread like that, and it is the single most important thing to understand before you buy the gun: "12 gauge ammo" is not one product with one price. Target loads, defensive buckshot and premium hunting shells are three different markets that happen to share a hull.

That matters because the practice shells and the defensive shells are not the same purchase. You will buy a case of the cheap ones and a box or two of the expensive ones, and the cheap ones are where your money actually goes. If you have read how many rounds it takes to get good, apply that number to the floor price above and you will see why the gun is the small line item.

What the entry tier gets you, and what it does not

Defensive-configured pump guns — 18.5-inch barrel, 4 to 7 rounds, bead or ghost ring sights — start lower than almost anything else you could reasonably stake a house on:

Most of these are imports. That is not automatically a problem — the pump action is a mature, simple mechanism and the import guns generally run — but it is where the compromises live. Expect a rougher action, a heavier trigger, a stock that fits nobody in particular, and a thin parts and accessory aftermarket. The domestic legacy pumps cost more and earn most of it in fit and support:

Note that the cheapest listings in that block are field guns with long barrels, not defensive configurations — the Security and Persuader models sit higher in the same line. This is the most common mistake we see in shotgun shopping: sorting by price and buying a 26-inch bird gun because the brand was right.

What the entry tier does not get you is a shorter learning curve. A cheap pump and an expensive pump both require you to run the action under stress without short-stroking it, and that is a trained skill, not a purchased one.

Is a semi-auto worth several times the money?

For home defense specifically: sometimes, and for one measurable reason. A gas or inertia gun sends less recoil into the shooter, which means faster follow-up shots and a shooter who is willing to practice more. That second effect is worth more than the first.

The bottom of the semi-auto market is not obviously better than a good pump. Cheap semi-autos are ammunition-sensitive in a way pumps are not: light target loads may not cycle them reliably, which is exactly the ammunition you will be practicing with. If you buy at this tier, verify your practice load and your defensive load both run before you trust either.

The top of the market is a different conversation:

Guns at this level — the Beretta 1301 and A300 Patrol, Benelli's M2 and M4 — are the reason serious shotgun shooters stopped arguing about pumps. They are also several times the price of the entry tier. Put that difference next to the per-shell cost in the index above and decide honestly which one buys you more capability.

12 gauge or 20 gauge?

The 20 gauge case is stronger than its reputation. Less recoil, lighter guns, and enough terminal effect for defensive distances inside a house. The real arguments against it are supply and selection:

Compare that against the 12 gauge block earlier on this page. The per-shell gap is narrower than most buyers expect — but the catalog depth is not close. Our 12 gauge listings outnumber 20 gauge by a wide margin, and the defensive buckshot selection in 20 gauge is a fraction of what is available in 12. You will pay similar money per shell and have fewer loads to pattern.

Pick 20 gauge if recoil is the limiting factor for the person who will actually use the gun. Pick 12 gauge if load selection matters more, which for most buyers it does.

What to load it with

Not birdshot. The reasoning is in birdshot vs buckshot vs slug, and it is the one shotgun question where the popular answer and the correct answer diverge most sharply.

For the actual load selection and current defensive pricing, our 12 gauge buckshot guide is the companion piece to this one — read it before you buy shells. Then browse everything currently listed on the 12 gauge caliber page and buy the practice volume separately:

Those are target loads, not defensive loads — that is the point. They are what you will shoot several hundred of while learning to run the gun, and they are where the shotgun budget actually goes. Do the arithmetic yourself:

Shotshell prices also move seasonally and with component costs in ways rifle ammunition does not; why ammo prices move covers the forces involved. And before you order a case of anything heavy, check ammo shipping restrictions for your address — shotshells are bulky, freight-sensitive and restricted in more places than buyers expect.

Barrel length, pistol grips and the legal line

A meaningful share of the "tactical" shotgun market sits close to a federal line, and the listings do not tell you which side. Shotguns below a threshold barrel length are federally regulated short-barreled shotguns requiring a registered transfer. Some 14-inch pistol-grip-only models are instead sold as ordinary firearms because they never had a shoulder stock and exceed a minimum overall length — a real distinction with real consequences if you get it wrong, and one that states layer their own rules on top of.

For the overwhelming majority of buyers, an 18.5-inch barrel with a real shoulder stock is the right answer, is legal essentially everywhere shotguns are, and handles better indoors than the short guns it is supposedly worse than.

Lights, optics and the rest of the bill

Budget for a weapon light before anything else. You cannot shoot what you have not identified, and a shotgun occupies both hands.

An optic is a genuine upgrade and a secondary one. A red dot shortens the time between mounting the gun and a valid sight picture, which is the part of shooting a shotgun that people are actually slow at — the reasoning in red dot vs LPVO transfers directly, minus the magnification question, which does not apply at in-home distances. The accessory catalog we track runs to more than 73,000 live listings, so the risk here is overspending on furniture, not finding it.

How we picked these

We did not shoot them, and we did not pattern them. AmmoSpotter does not run ballistics or accuracy testing and does not publish numbers it did not measure — the full reasoning is in how we rank ammunition, and it governs firearms the same way.

What we do have is every retail price in this category, updated continuously. The tiers above are defined by where real listings actually sit, and every block on this page re-reads the catalog when you load it. If a gun here looks expensive next to the grid beside it, the grid is right and the gun is not.

Frequently Asked Questions

Is a pump or a semi-auto better for home defense?+
A quality semi-auto is faster to shoot and noticeably softer in recoil, which matters more than most buyers expect when the stock is short and the shooter is not large. A pump is cheaper, tolerates any load without cycling concerns, and has fewer failure modes. The honest answer is that a $300 pump you practice with beats a $1,500 semi-auto you do not, and the gap between the two tiers in our index is several hundred rounds of training ammunition.
How much should I spend on a home defense shotgun?+
Defensive-configured pump shotguns start in the low hundreds in our live index and quality semi-autos run several times that. Budget the gun and the ammunition together: the shells needed to become competent with a shotgun often cost more than an entry-tier pump gun does. Spend what is left after you have funded the practice, not before.
Is 20 gauge enough for home defense?+
Yes for most defensive scenarios, and it recoils meaningfully less, which makes follow-up shots faster for smaller shooters. The trade-offs are load selection and price: 12 gauge has far more defensive loads available and a deeper discount market. Compare the two live price index blocks in this guide — the per-shell gap is smaller than most people assume, but the 12 gauge catalog is much larger.
What should I load a home defense shotgun with?+
Buckshot, in a load that patterns tightly from your specific barrel and choke. Birdshot does not penetrate reliably enough and slugs over-penetrate in most homes. Our buckshot guide covers load selection and current pricing; the short version is that you must pattern the load you choose rather than trust the box.
Are short-barrel and pistol-grip-only shotguns legal to buy?+
Some are sold as ordinary firearms and some are federally regulated short-barreled shotguns requiring a registered transfer, and the difference comes down to overall length and whether the gun ever had a shoulder stock. State and local rules add another layer and change. Verify the specific model with your dealer for your own jurisdiction before you order — the listing category is not legal advice.
Do I need a light or an optic on a defensive shotgun?+
A light, yes — identifying a target before firing is not optional, and a handheld light is not a substitute when both hands are on a shotgun. An optic is genuinely useful but secondary; bead sights work at in-home distances. Fund the light first, then the ammunition, then the optic.
