After years of storing rifles and handguns at home, I’ve learned that the best gun safe is not the biggest box or the one with the highest gun count printed on the door. It is the safe that fits your actual guns, fits the room you have, and opens the way you need it to when it matters.
That is how I built this guide. I narrowed a crowded market down to the 11 best gun safes on Amazon, ranked them by what thousands of real owners rate them, and I’ll tell you plainly where each one shines and where it falls short. The top-rated safe sits at #1.
Secure storage still matters a lot in the U.S. CDC data from eight states found that among households with a loaded firearm and a child present, a significant share of owners still kept at least one loaded firearm unlocked:
- 25.2% to 41.4% of those owners reported keeping at least one loaded firearm unlocked.
A good gun safe fixes that problem without making your guns hard to reach. Below are my picks, followed by the buying lessons I wish someone had told me before my first safe.

How I Ranked These Gun Safes
Every safe had to clear a hard bar before it could be ranked: at least 4.3 stars from 500 or more Amazon ratings, in stock when I last updated this guide, and a sensible backup if the main lock fails. A safe with a dozen reviews has not been lived with long enough to trust.
How the ranking works: I ordered the safes by their Amazon star rating, highest first. When two safes share the same rating, the one with more ratings ranks higher, because a 4.7 from 6,000 owners is stronger proof than a 4.7 from 600. That keeps the order transparent and based on real owners, not on which brand pays the most.
Then I judged every ranked safe on the same handful of things that actually matter once a safe is bolted down in your house, which is what shapes the “best for” label and who I would recommend it to:
- Real usable capacity, not the marketing number. Scoped rifles and optic-equipped pistols take far more room than the box suggests.
- Lock reliability and access speed, including whether there is a sensible backup if a battery or fingerprint reader fails.
- Build and pry resistance: steel gauge, bolt design, and how the door fits the frame.
- Fire protection, read honestly. A fire rating is a time and temperature claim, not a promise.
- Owner feedback over time, especially recurring complaints about locks, hinges, and fitment.
If you want the deeper technical side of security ratings, I broke it down in my guide on UL RSC vs TL-15 and TL-30 gun safe ratings.
The 11 Best Gun Safes, Ranked from Top Rated Down
Here are the best gun safes on the market right now.
1. BILLCONCH Biometric Gun Safe: Top Rated Overall
Amazon rating: 4.7 out of 5 stars from 6,400+ ratings
Why it ranks #1: It has the highest star rating on this list and by far the largest owner base, which is the strongest proof that the fingerprint reader keeps working after the first few months.
Why it made my list: It is the most proven budget handgun safe on Amazon, with thousands of owners behind it.
Key specs: Fits 2 standard pistols, fingerprint and PIN access, carbon steel shell with spring steel internals, interior LED light, 10 x 8.6 x 2.75 inches, one-year warranty.
When a handgun safe has more than six thousand ratings and still holds 4.7 stars, that tells me the fingerprint reader works for most people over time. That is the part that usually fails on cheap biometric boxes.
It is small enough for a nightstand drawer, a closet shelf, or a vehicle, and the interior light helps at night. Treat it as a quick-access lockbox rather than a burglary safe, and anchor or cable it so it cannot just be carried off.
Pros and Cons
| Pros | Cons |
|---|---|
| Huge owner base with consistently strong ratings | Thin steel compared with larger safes |
| Fast fingerprint access with PIN backup | Basic feature set with no app or alerts |
| Compact enough for drawers and vehicles | |
| Very affordable |
Who I’d recommend it to: First-time buyers who want a reliable, affordable fingerprint safe for one or two handguns.
Who should skip it: You want app alerts, room for more than two pistols, or a heavier box.
2. Vaultek LifePod 10: Best for Travel
Amazon rating: 4.7 out of 5 stars from 2,300+ ratings
Why it ranks #2: It ties for the top star rating, and with 2,300+ ratings it has the second-biggest track record of any safe here.
Why it made my list: It is the best travel lockbox I know of, because it is rugged, waterproof, and still quick to open.
Key specs: Backlit 4 to 8 digit keypad with over 87,000 combinations, backup key, anti-picking mode, airtight and dustproof seal, floats in water, T3 polymer shell, 9V battery rated up to a year with micro-USB backup power, steel security cable, TSA compliant, 7.75 x 6 x 1.75 inches, about 2 pounds.
Travel cases take abuse, and the LifePod handles it. It seals out water and dust, survives drops, and still opens in a second with the backlit keypad. You can also use it unlocked as a plain waterproof case.
It suits compact handguns, so measure your pistol before buying. If you want the rest of the brand lineup, my Vaultek gun safe guide covers it.
Pros and Cons
| Pros | Cons |
|---|---|
| Waterproof, dustproof, and floats | Fits compact handguns best |
| Fast backlit keypad with key backup | Polymer shell, not a steel safe |
| Light and TSA compliant for travel | |
| Huge owner base with excellent ratings |
Who I’d recommend it to: Anyone who carries a handgun in a vehicle, boat, or luggage and wants rugged, weatherproof protection.
Who should skip it: You need a full-size handgun safe for permanent home storage.
3. Grimtron Portable Car Gun Safe: Best for Cars on a Budget
Amazon rating: 4.7 out of 5 stars from 620+ ratings
Why it ranks #3: It matches the 4.7-star top rating but has fewer total ratings than the two picks above it, so it ranks third.
Why it made my list: It is the most affordable well-rated vehicle safe I found, and it does the basics right.
Key specs: Backlit 3 to 8 digit keypad, backup keys, USB-C emergency power port, alloy steel, padded interior, steel security cable, 11.02 x 7 x 1.85 inches, about 3.7 pounds.
A car safe has one job: keep a handgun locked and tethered when you have to leave it in the vehicle. This one slides under a seat, cables to the seat frame, and opens with a backlit code you can find in the dark.
The USB-C port is a nice touch. If the batteries die, a power bank gets you back in, and the keys are there as a last resort. Just do not leave the keys in the glove box.
Pros and Cons
| Pros | Cons |
|---|---|
| Very affordable for a well-rated steel lockbox | No biometric option |
| Backlit keypad plus backup keys | Thin steel, so the cable is the main theft deterrent |
| USB-C emergency power | |
| Low profile fits under most seats |
Who I’d recommend it to: Drivers who need a simple, cheap, and reliable way to lock a handgun in the car.
Who should skip it: You want fingerprint access or a safe for home use.
4. BILLCONCH Smart Multi-Pistol Safe: Best for Multiple Handguns
Amazon rating: 4.6 out of 5 stars from 1,200+ ratings
Why it ranks #4: It holds 4.6 stars from 1,200+ owners, the most ratings of any 4.6-star safe on this list.
Why it made my list: It holds several handguns upright in a bracket, so you are not stacking pistols on top of each other.
Key specs: Holds up to 4 pistols in a removable pistol bracket, fingerprint, PIN, app, and key access, auto-lock when the door closes, LCD screen with voice guidance, silent mode, automatic LED light, 11.41 x 11.81 x 10.24 inches.
Once you own more than two handguns, a flat drawer safe gets messy. The upright bracket here keeps each pistol separate and easy to grab, and the bar moves so you can fit different frame sizes.
Four ways in is plenty of redundancy, and the auto-lock means you cannot forget to lock it after closing the door. The app also keeps an unlock record, which is useful in a shared home.
Pros and Cons
| Pros | Cons |
|---|---|
| Upright pistol bracket keeps handguns organized | Bigger footprint than a nightstand box |
| Fingerprint, PIN, app, and key access | More electronics means more to maintain |
| Auto-locks when the door closes | |
| Unlock records through the app |
Who I’d recommend it to: Handgun owners with three or four pistols who want them organized and quick to reach.
Who should skip it: You only own one pistol or want something that fits inside a drawer.
5. Viking VS-52BLX In-Wall Safe: Best Hidden Gun Safe
Amazon rating: 4.6 out of 5 stars from 640+ ratings
Why it ranks #5: It also earns 4.6 stars, with fewer ratings than the BILLCONCH multi-pistol safe, which puts it fifth.
Why it made my list: Concealment is a layer of security too, and this is the cleanest hidden gun safe I would recommend.
Key specs: Fits between standard studs, 500 DPI fingerprint reader storing up to 32 prints, keypad, backup cross keys, silent mode, LED light, three adjustable shelves, motorized 20mm deadbolts, about 39 pounds, 4″ D x 14″ W x 19.3″ H.
A thief cannot attack a safe they never find. The VS-52BLX sits flush between studs, so behind a mirror, a picture frame, or inside a closet it disappears. Fingerprint, PIN, and key access make it quick for a handgun you want close by.
The limitation is depth. Four inches is fine for a handgun, cash, and documents, and the central lockbox takes up some interior room. Plan the install around your stud spacing before you buy.
Pros and Cons
| Pros | Cons |
|---|---|
| Flush in-wall design is much easier to conceal than most small safes | Limited interior depth compared with a conventional handgun safe |
| Fast biometric, keypad, and key access give good redundancy | Central lockbox reduces usable storage space in the middle |
| Heavier-duty feel than many cheap wall safes in this class | |
| Strong fit for hidden handgun and valuables storage between studs |
Who I’d recommend it to: Owners who want a concealed handgun and valuables safe with fast biometric access and no floor footprint.
Who should skip it: You need more interior depth, larger capacity, or heavy-safe burglary resistance.
6. STOPBOX Mechanical Handgun Safe: Best No-Battery Safe
Amazon rating: 4.5 out of 5 stars from 1,000+ ratings
Why it ranks #6: At 4.5 stars from 1,000+ owners, it is the highest-rated safe here that has no electronics at all.
Why it made my list: It is the quick-access handgun box for people who do not trust batteries or fingerprint readers.
Key specs: Fully mechanical lock with 81 user-set combinations, no batteries or electronics, TSA compliant, works with a padlock or security cable, full-size interior 9.25 x 7.15 x 1.75 inches, glass-reinforced polycarbonate shell, about 1.8 pounds.
Every electronic safe on this list needs a backup plan for a dead battery. The STOPBOX does not. You press the plungers in your set pattern and it opens, every time, which is why it has such a loyal following.
Be clear about what it is. The shell is polymer, not steel, so it is about keeping kids and curious guests out while giving you fast access, not stopping a determined thief. Cable it to something solid. I go deeper in my StopBox review.
Pros and Cons
| Pros | Cons |
|---|---|
| No batteries, no fingerprint reader, nothing to fail | Polymer shell offers limited burglary resistance |
| Fast once you learn your combination | Not designed for wall mounting |
| Light, portable, and TSA compliant | |
| Works with a cable or padlock |
Who I’d recommend it to: Owners who want dead-simple, always-ready access to a handgun at home or on the road.
Who should skip it: You want steel construction or a safe that can be bolted down.
7. BBRKIN Biometric Rifle Safe (5-7 Gun): Best Rifle Safe
Amazon rating: 4.4 out of 5 stars from 930+ ratings
Why it ranks #7: It is the top-rated long gun safe on this list, with the most ratings of any 4.4-star pick.
Why it made my list: It is the highest-rated long gun safe I found, and it has the toughest door in its price class.
Key specs: Holds 5 to 7 rifles (rated), Smart Align biometric scanner, 4-digit backlit keypad with proximity sensor, spare keys, 14-gauge steel body, 11-gauge steel door, 5 solid locking bolts with anti-pry bars, interior hinges, separate internal lockbox, rifle clearance of 50.5 inches, 57 x 14 x 12 inches.
Slim rifle safes usually cut corners on the door, and the door edge is where pry attacks happen. The BBRKIN uses an 11-gauge door with five solid bolts and interior hinges, which is a noticeably better package than most cabinets this size.
The internal lockbox is a smart touch. You can keep a handgun, cash, or documents behind a second lock, which matters if other adults in the house have the main code.
Plan on five rifles, not seven, once optics come into play. Stock has been limited at times, and BBRKIN also sells a keypad-only version of this safe with 2,000+ ratings if you do not want biometrics.
Pros and Cons
| Pros | Cons |
|---|---|
| 11-gauge door and 5 locking bolts are stronger than most slim rifle safes | Realistic capacity drops with scoped rifles |
| Separate internal lockbox for handguns and valuables | Stock can run low on Amazon |
| Biometric, keypad, and key access | Not fire rated |
| Narrow footprint fits closets and corners |
Who I’d recommend it to: Rifle owners who want a compact long gun safe with a stronger door and a separate locked space for handguns.
Who should skip it: You need room for more than five optic-equipped long guns.
8. RPNB Mounted Biometric Handgun Safe: Best Mounted Handgun Safe
Amazon rating: 4.4 out of 5 stars from 800+ ratings
Why it ranks #8: It holds 4.4 stars from 800+ owners, second only to the BBRKIN among the 4.4-star safes.
Why it made my list: It is the best value quick-access handgun safe for tight spots beside the bed or under a desk.
Key specs: Slide-away door, fingerprint reader, backlit keypad, backup keys, silent mode, interior light, California DOJ certified, about 11.5 x 9.29 x 2.8 inches and 10.6 pounds, fits one full-size handgun up to 8.5 inches plus a spare magazine.
The RPNB mounts vertically, so it fits on the side of a nightstand, under a desk, or inside a closet where a box safe would not. The slide-away door is quicker and quieter than a lid that flips up.
My one firm piece of advice: learn the keypad code and use it as your primary backup, because fingerprint reliability is mixed. Pistols with lights or optics will not fit. For more models from the brand, see my RPNB gun safes guide.
Pros and Cons
| Pros | Cons |
|---|---|
| Slim mounted design works very well in tight bedside or desk setups | Not a good fit for pistols with lights, optics, or bulkier add-ons |
| Fast slide-away opening format is more bedside-friendly than many box safes | Biometric reliability appears mixed |
| Keypad, fingerprint, and backup keys give useful layered access | |
| Good value for a mounted safe with light and silent mode |
Who I’d recommend it to: Owners who want an affordable, compact mounted handgun safe for a simple full-size pistol.
Who should skip it: Your handgun carries an optic or weapon light, or you want to rely on biometrics alone.
9. Hornady RAPiD Safe Night Guard: Best Bedside Safe
Amazon rating: 4.4 out of 5 stars from 710+ ratings
Why it ranks #9: It earns 4.4 stars from 710+ owners and is the fastest bedside safe to open on this list.
Why it made my list: It is the fastest bedside safe I know of to open, because RFID entry works by touch in the dark.
Key specs: RFID entry with 4 programmable tags (wristband, key fob, 2 decals), keypad, 2 barrel keys, 14-gauge steel, 2 hardened locking lugs, 1,500 lb security cable, built-in clock, 2 USB-A charging ports, AC plus battery power, spring-assist drawer, interior 2.2 x 9.2 x 6.9 inches, about 13.8 pounds.
RFID is the access method I trust most beside the bed. You tap the wristband or fob and the drawer pops, with no fingerprint angle to get right and no code to punch in half asleep.
It also looks like a bedside clock and charges your phone, so it actually lives on the nightstand. If charging is the feature that matters most to you, see my roundup of the best nightstand gun safes with a phone charger.
Pros and Cons
| Pros | Cons |
|---|---|
| RFID entry is very fast and works in the dark | Needs AC power for daily use |
| Doubles as a clock and charging station | Fits one full-size handgun comfortably |
| 14-gauge steel with a heavy security cable | |
| Keypad and barrel key backups |
Who I’d recommend it to: Anyone who wants the quickest possible bedside access to a single handgun.
Who should skip it: You want biometric access or need room for several pistols.
10. KAER Biometric 14-15 Gun Safe: Best High-Capacity Gun Safe
Amazon rating: 4.4 out of 5 stars from 540+ ratings
Why it ranks #10: It shares the 4.4-star rating but has the fewest ratings in that group, so it ranks tenth. It is still the biggest-capacity safe here.
Why it made my list: It is the largest-capacity safe on this list and gives you biometric access without a premium price.
Key specs: Holds 14 to 15 long guns (rated), fingerprint reader storing up to 30 prints, digital keypad, emergency key, removable gun racks, overhead compartment for handguns, door hooks and ammo boxes, 15-gauge cold-rolled steel, 57 x 18.5 x 15.8 inches, about 78 pounds.
If you need room for a growing long gun collection, this is the safe I would look at first. The KAER pairs a fast fingerprint reader with a keypad and key backup, which is exactly the layered access I want on any electronic safe.
The interior is the part I like most at this price. The racks come out and move around, so you can set it up around scoped rifles instead of forcing them into fixed slots, and the overhead compartment keeps handguns and magazines off the floor of the safe.
My honest caution: ignore the 15-gun number. Guns taller than 45.5 inches only fit once you pull the shelves and hanging cabinet, and scoped rifles eat space fast. If you are deciding between big-safe sizes, my Wasatch 24 vs 40 gun safe comparison shows how quickly advertised capacity shrinks. For the full lineup, see my KAER gun safe guide.
Pros and Cons
| Pros | Cons |
|---|---|
| Fingerprint, keypad, and key give you three ways in | 15-gauge steel is cabinet-grade, not vault-grade |
| Removable racks fit scoped rifles better than fixed slots | Long guns over 45.5 inches need the shelves removed |
| Overhead compartment and door storage keep handguns and gear organized | Not fire rated |
| Strong price for the capacity and access features |
Who I’d recommend it to: Owners of a small to mid-size rifle and shotgun collection who want quick biometric access and a flexible interior at a fair price.
Who should skip it: You need fire protection or heavy-safe burglary resistance. Budget for a traditional fire-rated safe instead.
11. KAER Long Gun Safe (Assembled): Best No-Assembly Long Gun Safe
Amazon rating: 4.3 out of 5 stars from 840+ ratings
Why it ranks #11: It clears my 4.3-star minimum with 840+ ratings and is the only long gun safe here that arrives fully assembled.
Why it made my list: It arrives fully assembled and fits rifles up to 53 inches, which most budget cabinets cannot handle.
Key specs: Holds 3 to 5 rifles up to 53 inches plus 4 to 5 handguns, digital keypad, 2 backup keys, external emergency power box, 15-gauge steel, 0.8-inch anti-pry active bolts, door organizer, wrong-code alarm, sensor light, 4 pre-drilled anchor holes, 54.33 x 11.8 x 11.02 inches, about 63 pounds.
Not everyone wants to spend an afternoon assembling a gun cabinet. This KAER shows up built, so you anchor it and load it. The 53-inch height clearance is the real reason I picked it, because it fits longer shotguns that tall-but-short budget safes do not.
The external emergency power box means a dead battery will not lock you out, and the door organizer holds magazines and small gear. Scoped rifles fit best stored sideways or with the optic removed, so keep that in mind.
Pros and Cons
| Pros | Cons |
|---|---|
| Ships fully assembled | Keypad only, no biometric option |
| Fits long guns up to 53 inches | Narrow interior is tight for scoped rifles |
| External emergency power plus 2 backup keys | Not fire rated |
| Door organizer and handgun space add useful storage |
Who I’d recommend it to: Owners of two to five long guns who want a no-assembly cabinet that fits longer shotguns.
Who should skip it: You want fingerprint access or plan to store several scoped rifles.
What I Look For Before Buying a Gun Safe
These are the lessons that matter more than any brand name. I check every gun safe against them.
Real capacity matters more than the number on the box
Advertised capacity is a ceiling. Scoped rifles, pistol grips, door organizers, and shelving eat space fast, so a “40 gun” safe often holds 16 to 24 guns in a normal setup. My rule is to buy roughly double the space you think you need. You will grow into it.
Lock type should match how you use the safe
Mechanical locks are slower but never need batteries. Electronic keypads are fast and familiar. Biometric locks are excellent for quick access, but only when the reader is good, so I always want a keypad or key backup. Research shows the balance matters: about half of U.S. gun owners report storing firearms locked and unloaded, while most still want access in under 60 seconds.
Read fire ratings honestly
A fire rating like 60 minutes at 1,400°F tells you how long the safe was tested to protect contents at a stated temperature. It is not a guarantee, and paper, electronics, and optics all tolerate heat differently. If you store passports, deeds, or hard drives with your guns, a real rating is worth paying for. None of the safes on this list carry a fire rating. When I filtered for safes with at least 500 owner ratings on Amazon, the fire-rated rifle safes simply did not have that track record yet, so if fire protection is a must, buy a rated safe from a local dealer who can deliver and anchor it.
Steel, bolts, and pry resistance
Lower gauge means thicker steel, so 12-gauge beats 14-gauge, which beats 16-gauge. Bolt count matters less than how well the door edge resists prying. That is where cheaper safes usually fail.
Anchoring and placement
An unanchored safe can be tipped over and worked on, or simply carried away. I bolt every safe I own to the floor or wall. Pick an interior location away from exterior walls and windows, ideally a bedroom closet or basement corner with solid flooring.
Humidity control
Closed steel boxes trap moisture. A dehumidifier rod or desiccant pack plus a light coat of protectant keeps rust away. My guide to the best oil for firearms covers what I use before long-term storage.
Gun Safe Mistakes I See Owners Make
- Buying for today’s collection instead of the one you will own in five years.
- Trusting a biometric reader with no keypad or key backup.
- Skipping anchoring because the safe “feels heavy enough”.
- Leaving the backup key inside the safe or somewhere obvious.
- Putting the safe in a garage or damp basement without humidity control.
- Choosing by gun count alone instead of usable space for scoped rifles.
If budget is tight, a well-anchored entry-level safe still beats no safe. My KAER gun safe guide covers affordable options that do the basics well.
Final Thoughts on the Best Gun Safes
The top-rated gun safe on this list is the BILLCONCH Biometric Gun Safe, and with 4.7 stars from more than 6,400 owners it earns the #1 spot for anyone storing one or two handguns. For long guns, the BBRKIN Biometric Rifle Safe is the highest-rated pick, and the KAER Biometric 14-15 is the one to get if you need more room. For the car or travel, grab the Vaultek LifePod 10, and if you never want to think about batteries, get the STOPBOX.
Whatever you choose, size for real capacity, read fire ratings honestly, and bolt it down. That combination matters more than any logo on the door, and the peace of mind of knowing your guns are secure from kids, guests, and burglars is worth every bit of effort.
FAQs
The top-rated gun safe overall is the BILLCONCH Biometric Gun Safe, with 4.7 stars from more than 6,400 Amazon ratings. For rifles and shotguns, the BBRKIN Biometric Rifle Safe is the highest-rated long gun safe, and the KAER Biometric 14-15 is the best pick if you need more capacity.
Every safe needed at least 4.3 stars from 500 or more Amazon ratings and had to be in stock. I then ranked them by star rating, highest first, and broke ties by the number of ratings, so the safe with the strongest owner track record sits at #1.
Gun safes limit unauthorized access, reduce theft risk, and keep firearms away from children, guests, and anyone else in your home who should not handle them. CDC data shows unlocked storage is still common, so a safe remains one of the most effective safety steps a gun owner can take.
No safe is fireproof in the literal sense. A fire rating means the safe was tested to protect contents for a stated time at a stated temperature, such as 60 minutes at 1,400°F. Treat it as fire resistance, not a guarantee.
For a full-size gun safe, I look for 12-gauge or thicker steel. 14-gauge is acceptable for budget and cabinet-style safes, while 16-gauge and thinner steel is mainly found in small handgun safes and lockboxes.
Choose an interior location with solid flooring, away from exterior walls, windows, and moisture. Bedroom closets and basement corners are common choices. Wherever it goes, bolt the safe to the floor or wall.
Buy roughly twice the capacity you think you need. Advertised gun counts assume bare rifles packed tightly, so scoped rifles, AR-style platforms, and accessories will fill a safe much faster than the number suggests.
