Best Home Defense Gun (2026): 7 Picks by Platform, Ranked

OAOSS America Editors · Editorial Team September 29, 2026 15 min read How we test

The worst night of your life won't come with a warning, a timeout or a second try. It will come at 2 a.m., half-awake, in a dark hallway, with people you love behind you. The best home defense gun is the one you can reach fast, run without thinking and hit with when your hands are shaking. That's the whole test.

We compared the handguns, shotguns, rifles and pistol-caliber carbines that buyers actually choose for the house, and ranked seven specific models on how easy they are to run and hit with, capacity, reliability features, and what they cost new on Guns.com on September 26, 2026. This is a research guide built from maker specs and live prices, not a hands-on test, and we flag every spot where a fact couldn't be confirmed.

The short answer

For most homes, a compact 9mm pistol you practice with beats a bigger gun you don't. Our picks:

Best overall: Glock 19 V, from about $540 new. Check price →
Best shotgun: Mossberg 590A1 (18.5-in), from about $640. Check price →
Easiest to shoot well: Ruger PC Carbine 9mm, from about $600. Check price →
Best rifle: S&W M&P15 Sport III, from about $700. Check price →
Best budget: Maverick 88 Security 12 ga, about $260. Check price →

Pair the Glock 19 with the PC Carbine and one set of Glock magazines feeds both guns. All prices are Guns.com new listings on September 26, 2026.

How we chose

Nobody at OSS America ran these guns for this guide. We built the ranking from each maker's published specs (Glock, Smith & Wesson, Mossberg, Ruger), the lowest new price we could find on Guns.com for each exact configuration, and whether the maker still lists the gun as current. We weighed five things: how easy it is to hit with for an average shooter, controls you can run half-asleep, capacity, durability features, and price. Two guns fell off the list during research: Ruger's AR-556 page now returns "page not found" on ruger.com, and the standard GP100 revolvers show as limited or unavailable there.

Handgun, shotgun or rifle? Pick the platform first

Every platform can defend a home. The right one depends on who in the house will use it, where it will be stored and how much you'll practice.

Platform	What it does well	The trade-off	Best for
Handgun	Stores in a small quick-access safe; one hand free for a phone, a light or a child	Hardest of the three to shoot accurately under stress	Everyone who also wants to carry
Pump shotgun	One shot puts a lot of lead on target; cycles any load; cheapest way in	Recoil, lower capacity, and you have to run the pump	Budget buyers and traditionalists
Semi-auto shotgun	Shotgun power without working a pump	Price, and pickier about light loads	Buyers who want the best shotgun, period
AR-15 rifle	Most capacity, easy hits from the shoulder, room for a light	Loud indoors; restricted in some states	Rural homes and experienced shooters
Pistol-caliber carbine	Mild 9mm recoil with a stock; can share magazines with a pistol	Longer than a handgun in tight hallways	New shooters and smaller shooters

All seven at a glance

The 7 best home defense guns, ranked

Glock 19 V

Best overall home defense gun

Guns.com, new: from about $540 · Per round on board: about $36

If you want one gun that guards the house tonight and rides on your hip tomorrow, this is where most people should start. The Glock 19 is a compact 9mm, so it is small enough for a nightstand safe and a small hand, but it still carries 15 rounds in the standard magazine. The V is the version Glock currently lists on its commercial site, with the Marksman barrel, no finger grooves, swappable backstraps and an ambidextrous slide stop.

What that means at 2 a.m.: there is no manual safety to forget, the controls work for lefties too, and the grip adjusts to your hand instead of the other way around. Glock also lists optional 17-, 24-, 31- and 33-round magazines, and the same magazines feed the Ruger PC Carbine (#3) through the extra magazine well Ruger includes. One ammo type, one magazine type, two guns. That is a simple home-defense plan.

On price, Guns.com had the G19 V new from $539.00 on September 26 (the listing showed "was $647.00"). Glock doesn't publish an MSRP on its site, so compare a few listings. Guns.com also still had new Gen5 G19s from $575.99 the same day.

Caliber	9mm
Capacity	15 standard (17/24/31/33 optional)
Barrel	4.02 in
Weight	23.63 oz with empty magazine; 30.16 oz loaded
Size	7.28 in long, 1.34 in wide, 5.04 in tall
Safety	Three passive internal safeties (no manual lever)

Pros

+ Compact enough to store in a small safe and to carry, big enough to shoot well
+ 15-round standard magazine; larger magazines listed by Glock
+ Ambidextrous slide stop and reversible magazine catch
+ Magazines also run in the Ruger PC Carbine with its included Glock magazine well
+ Lowest new price in our list for a full-capacity pistol

Cons

− A handgun is harder to shoot accurately under stress than a long gun
− No manual safety, so holster and storage discipline matter
− Glock lists no MSRP, so prices vary more between sellers

Mossberg 590A1 (18.5-inch, 7-shot)

Best home defense shotgun

Mossberg 590A1 (18.5-inch, 7-shot). Photo: Guns.com listing.

Guns.com, new: from about $640 · MSRP: $770.00 · Per round on board: about $91

The pump shotgun is the classic answer for a reason: one trigger pull puts a lot of lead on target at bedroom distances, and a pump action doesn't care what shell you feed it. Mossberg calls the 590A1 the most durable of its pump guns. It meets MIL-SPEC 3443G and gets a heavy-walled barrel, a metal trigger guard and safety, and a Parkerized finish, the parts cheaper pumps make of plastic.

The 18.5-inch, 7-shot version (Mossberg #50766) holds 6+1, weighs 7 lb and measures 39.5 inches. The safety sits on top of the receiver where either thumb can reach it, which helps lefties and anyone grabbing the gun in the dark. Mossberg lists it at $770.00; Guns.com had 18.5-inch 590A1s new from $636.99 on September 26.

Gauge	12 ga, 3-in chamber
Capacity	6+1
Barrel	18.5 in heavy-walled, cylinder bore
Weight / length	7 lb / 39.5 in
Sights	Bead (this SKU)
Safety	Top-mounted ambidextrous

Pros

+ Built to Mossberg's toughest pump spec (MIL-SPEC 3443G)
+ Metal trigger guard and safety instead of polymer
+ Ambidextrous tang safety
+ Pump action cycles any load you feed it

Cons

− 12-gauge recoil is real for small or new shooters
− You have to work the pump under stress
− Only 6+1 in this length
− Bead sight on this SKU; ghost-ring versions cost more

Ruger PC Carbine (9mm)

Easiest to shoot well

Ruger PC Carbine (9mm). Photo: Guns.com listing.

Guns.com, new: from about $600 · MSRP: $799.00 · Per round on board: about $36

A pistol-caliber carbine is the quiet star of home defense. You get the stability of a shoulder stock and a long sight radius with a mild 9mm cartridge, so hits come easier for new shooters, smaller shooters and anyone who flinches at a 12 gauge. Ruger's PC Carbine adds a tungsten "dead-blow" weight in the bolt that Ruger says reduces felt recoil and muzzle rise.

The smart part is the magazine well. Ruger ships it with a well for its own SR-Series and Security-9 magazines and a second well that takes Glock magazines. Pair it with the Glock 19 (#1) and one set of magazines feeds both guns. It also breaks down into two halves, so it stores in a smaller case or safe. Ruger lists model 19100 at $799.00 (marked "Limited Availability" on its site); Guns.com had it new from $604.99 on September 26.

Caliber	9mm
Capacity	17 (ships with one SR-Series/Security-9 magazine)
Barrel	16.12 in, threaded 1/2-28, fluted
Weight / length	6.8 lb / 34.37 in
Length of pull	12.62 to 14.12 in with spacers
Extras	Interchangeable magazine wells incl. Glock; takedown

Pros

+ Mild recoil and easy hits for most shooters
+ Runs Glock magazines with the included magazine well
+ Takedown design stores small
+ Adjustable length of pull

Cons

− 9mm still penetrates interior walls, like any defensive round
− Ruger marks the base model 'Limited Availability'
− Longer than a handgun to move through tight hallways

Smith & Wesson M&P15 Sport III

Best rifle for home defense

Smith & Wesson M&P15 Sport III. Photo: Guns.com listing.

Guns.com, new: from about $700 · MSRP: $799.00 · Per round on board: about $23

An AR-15 gives you the most rounds on board of anything here (30 in the standard magazine), a stock to steady your aim and plenty of rail space for a light. Smith & Wesson's M&P15 Sport III has a 16-inch barrel with 1:8 twist, a free-float handguard and a mid-length gas system that S&W says brings less felt recoil. It also keeps the forward assist and dust cover some budget ARs skip.

S&W lists it at $799.00 and backs it with its Lifetime Service Policy. Guns.com had 30-round versions new from $699.99 on September 26. Before you buy, check your state: some states restrict AR-style rifles or magazine capacity, which is why S&W sells 10-round "compliant" versions.

Caliber	5.56 NATO
Capacity	30
Barrel	16 in, 1:8 twist, 5R rifling
Weight	104.32 oz (about 6.5 lb)
Gas / handguard	Mid-length / free-float
Extras	Forward assist, dust cover, forged integral trigger guard

Pros

+ Most capacity in this guide
+ Easy to shoot accurately from the shoulder
+ Free-float handguard for a light or optic
+ Lowest price per round of capacity in our chart

Cons

− Loud indoors; hearing protection matters if you ever have to use it
− Restricted or limited in some states
− Longer than a handgun or PCC

Smith & Wesson M&P9 M2.0 Optics Ready (Full Size)

Best full-size handgun

Smith & Wesson M&P9 M2.0 Optics Ready (Full Size). Photo: Guns.com listing.

Guns.com, new: from about $650 · MSRP: $699.00 · Per round on board: about $38

If the pistol will live at home rather than on your belt, a full-size gun is easier to shoot well: longer grip, more weight to soak up recoil, more rounds. Smith & Wesson's M&P9 M2.0 Optics Ready gives you 17 rounds, a slide already cut for a red dot (S&W includes seven mounting plates) and four palmswell grip inserts so the gun fits your hand.

S&W lists 29 oz, 1.16 inches wide and 5.7 inches tall, with a flat-face trigger and an embedded stainless chassis. MSRP is $699.00; Guns.com had the 17-round, 4.25-inch model new from $644.99 on September 26. Want a red dot on it? Our best 9mm pistols guide covers more options.

Caliber	9mm
Capacity	17
Weight	29 oz (S&W listing)
Size	1.16 in wide, 5.7 in tall
Optics	Slide cut, seven mounting plates included
Fit	Four palmswell inserts (S, M, ML, L)

Pros

+ 17 rounds with a full grip for better control
+ Optics-ready out of the box
+ Four grip sizes in the box
+ Lifetime Service Policy from S&W

Cons

− Bigger than the Glock 19 to carry
− Price near the Glock despite no carry advantage
− Several M&P9 M2.0 variants; the plain model is marked discontinued, so check the listing

Maverick 88 Security (18.5-inch)

Best budget home defense gun

Maverick 88 Security (18.5-inch). Photo: Guns.com listing.

Guns.com, new: from about $260 · MSRP: $290.00 · Per round on board: about $43

Tight budget? The Maverick 88 Security is the least expensive way into a reliable pump 12 gauge from a major maker. It is built by Mossberg, shares the dual extractors, steel-to-steel lockup and twin action bars of Mossberg's pumps, and takes Mossberg 500 accessory stocks and barrels (within gauge and capacity).

The 18.5-inch version (#31023) holds 5+1 and weighs 6.25 lb. Mossberg lists it at $290.00; Guns.com had it new for $257.99 on September 26 (listing UPC matches the Mossberg page). Put the money you save toward a quick-access safe, a light and a class. That trio does more for your family than a pricier gun.

Gauge	12 ga, 3-in chamber
Capacity	5+1 (20-in version: 7+1)
Barrel	18.5 in, blued, cylinder bore
Weight / length	6.25 lb / 39.5 in
Safety	Cross-bolt
MSRP	$290.00

Pros

+ Cheapest gun in this guide by a wide margin
+ Mossberg-built pump internals
+ Takes Mossberg 500 accessory stocks and barrels

Cons

− Cross-bolt safety instead of the Mossberg tang safety
− Blued finish needs more care than Parkerized
− 5+1 in the short barrel

Beretta 1301 Tactical

Best semi-auto shotgun (premium pick)

Beretta 1301 Tactical. Photo: Guns.com listing.

Guns.com, new: from about $1,660 · Per round on board: about $237

The Beretta 1301 Tactical is the shotgun for people who want 12-gauge power without working a pump. It is gas-operated, so each shot cycles the next shell for you, and Beretta built it for law enforcement and home defense: oversized charging handle, bolt release and safety, a ghost-ring rear sight, and a Picatinny rail on the receiver for an optic.

It is the most expensive gun here. Guns.com had it new from $1,660.99 on September 26 (listing "Retail $1,760.00"). Beretta's own site sat behind a security check we couldn't pass, so specs here come from the Guns.com listing. Note that listing could not ship to AK, CA, CT, HI, IL, MA or NJ. Our home defense shotgun guide covers the 1301-based Langdon Tactical Patrol and other semi-autos.

Gauge	12 ga
Capacity	7 (Guns.com listing)
Barrel	18.5 in, OptimaBore, Improved Cylinder choke
Action	Gas-operated semi-auto (Blink system)
Sights	Ghost-ring rear, interchangeable front
Stock	Length of pull adjustable with spacers

Pros

+ No pump to work under stress
+ Controls sized for gloves and adrenaline
+ Optics rail on the receiver
+ Adjustable length of pull, drop and cast

Cons

− More than six times the Maverick's price
− Gas guns can be pickier about very light loads than a pump
− Shipping limits on some listings

See Beretta 1301 at Guns.com →

Which should you buy?

You want one gun for the house and for carry: Glock 19 V. Add the Ruger PC Carbine later and share magazines.
You want a shotgun that will outlive you: Mossberg 590A1.
A new or smaller shooter will use it: Ruger PC Carbine. A stock and a 9mm make hits easier.
You live rural and train with a rifle: S&W M&P15 Sport III, where your state allows it.
Your budget is under $300: Maverick 88 Security, and spend the rest on a safe and a class.
Money is no object and you want a shotgun: Beretta 1301 Tactical.

Safety, storage and the law (the short version)

A home defense gun has two jobs: be ready for you, and be unreachable for everyone else. Three habits cover most of it.

Store it locked but quick to reach. A quick-access safe by the bed keeps kids and visitors out while you can still get to the gun in seconds. Our best pistol safes guide compares biometric, keypad and mechanical options. Many states also have storage and child-access laws, so check yours.
Train with the exact gun and load you'll use. A class with a certified local instructor, plus regular practice, matters more than any spec in this guide. Know what's behind every wall you might shoot toward: any round that can stop an attacker can also go through interior walls.
Know your local laws. Self-defense law, magazine limits, "assault weapon" rules and transport rules vary by state and even by city. When in doubt, ask a local attorney or your state's official resources before you buy.

Buying online

Guns.com ships your gun to the licensed dealer (FFL) you pick on a map at checkout. You bring a valid state ID, and the dealer runs any required background check before you take it home. Some listings can't ship to certain states. Our Is Guns.com legit? guide walks through the whole process and the fees.

Frequently asked questions

What is the best gun for home defense?

For most people, a compact 9mm pistol like the Glock 19 V (from $539.00 new on Guns.com on September 26, 2026). It stores in a small safe, carries 15 rounds and doubles as a carry gun. If you'll only ever keep it at home, a pistol-caliber carbine like the Ruger PC Carbine or a pump shotgun like the Mossberg 590A1 is easier to hit with.

Is a shotgun or a handgun better for home defense?

A shotgun is easier to hit with and hits harder at room distances, but it's long, it kicks, and pumps hold 5 to 8 shells. A handgun is easier to store, lets you keep a hand free, and holds more rounds, but it takes more practice to shoot well under stress. Choose the one you'll actually train with.

What caliber is best for home defense?

The guns in this guide cover the common choices: 9mm (Glock 19 V, M&P9, Ruger PC Carbine), 12 gauge (590A1, Maverick 88, Beretta 1301) and 5.56 NATO (M&P15 Sport III). Pick the one you can shoot accurately and afford to practice with, then choose a quality defensive load. Every one of them can go through interior walls.

Is an AR-15 good for home defense?

It can be: 30 rounds, a stock for steady aim and room for a light. The downsides are muzzle blast indoors and legal limits in some states, which is why makers like S&W sell 10-round compliant versions. Check your state and local law first.

What's the cheapest reliable home defense gun?

In this guide, the Maverick 88 Security 12 gauge: $257.99 new on Guns.com on September 26, 2026 (Mossberg lists it at $290.00). It's built by Mossberg with the same basic pump design as its bigger brothers.

Can I buy a home defense gun online?

Yes. You buy and pay online, the gun ships to a licensed dealer (FFL) you choose, and you pick it up with a valid state ID after the dealer runs any required background check. Age rules and local laws still apply, and some listings won't ship to some states.

How should I store a home defense gun?

Locked, but fast to reach: a quick-access safe near the bed is the common answer. Keep it out of reach of children and anyone who shouldn't have it, and check your state's storage laws.

The bottom line

If you want one gun, get the Glock 19 V, a quick-access safe and a class. If you want the easiest gun to shoot well, get the Ruger PC Carbine. If you want a shotgun, get the Mossberg 590A1, or the Maverick 88 if money is tight. Then practice until running it is boring. Boring is what you want at 2 a.m.
