Best Fireproof Gun Safes: 45 Minutes or More, and Who Says So

Why this rule: 45 minutes, in writing, on a gun safe

This list starts from every gun safe we track and keeps only those with a stated fire rating of 45 minutes or more. Then it sorts them: longest rating first, and within the same rating, highest test temperature first.

The rule has one job. It separates gun safes with a fire number from gun safes with a fire adjective. "Fire resistant" on its own describes an intention. A rating with minutes is something you can compare, question and hold the maker to.

Why 45 minutes and not 30? Because this is a best-of list, and a floor that lets in every short claim stops being a filter. Shorter ratings aren't worthless. They're on the full fire-rated gun safes table, where every gun safe with a stated fire rating appears.

The rule does not ask who tested the safe. That's deliberate. If it did, the list would be very short, because most fire numbers on gun safes are the manufacturer's own. Instead, the list keeps both kinds and labels them. You decide how much weight a claim deserves. We make sure you can see which kind it is.

The best fire-resistant gun safe is a sentence with three parts

A fire rating is how long, how hot, and who tested it. Drop one part and it stops being a rating. Read every row on this list for all three.

How long. The minutes of fire exposure. This is the number the list sorts by, and the one printed largest on the box.

How hot. Two very different numbers share this word. An in-house rating usually names a furnace temperature: how hot it was outside the safe. A UL 72 rating names a class, and UL describes the class as the maximum interior temperature during the test. Class 350 means the inside stayed at or below 350°F, and UL says it is intended to protect paper records. Class 150 adds non-paper records. The outside number describes the fire. The inside number describes the result.

Who tested it. An independent lab such as UL, or Intertek, which issues the ETL marks and is an OSHA-recognized testing laboratory. Or the manufacturer itself. An independent rating is the stronger claim, because the lab has no safe to sell.

Some UL fire ratings add an impact test, where the product is dropped 30 feet while hot and put back in the furnace. Not every UL 72 rating includes it. If a label says "impact", that's a separate, extra test.

How to read the best gun safe fire rating list

• Minutes first, then temperature. The sort is a reading order. A 150-minute claim from the maker sits above a 90-minute rating from a lab, because the rule sorts by minutes, not by who signed.
• Rated vs claimed. "Rated" names a lab. "Claimed" means the manufacturer states the number and no lab is named. The verdicts spell out which.
• Higher temperature isn't automatically better. Two in-house claims at different furnace temperatures came from different tests. A UL class and a furnace temperature can't be converted into each other at all. Compare like with like.
• A dash ("—"). Nobody we found put that value in writing. On this page, a dash in the steel or lock columns is common. Read it as a question for the seller.
• The burglary column is separate. UL RSC is a burglary rating under UL 1037. A long fire claim on thin steel is still thin steel.

The most fire-resistant gun safe on paper is the one with the longest rating from an independent lab, in a class that fits what you store. Everything else on the list is a trade-off you should make on purpose: more minutes from the maker, or fewer minutes from a lab.

Best home gun safe for fire and water: the second claim

Some safes on this list add a water claim to the fire claim. A water rating has the same three parts as a fire rating: how long, how deep, and who tested it.

That matters after a house fire, because the water that puts out a fire has to go somewhere. A safe that survives the heat can still let water in at the door. A water claim that names depth and time is useful. A water claim that names a lab is better.

The water claims on gun safes in this list are, at the time of our last check, the manufacturer's own. Treat them as claims. For safes and boxes chosen for water, see our waterproof safes page.

The door seal is the part you can look after. Many fire-rated doors use an intumescent seal, which Liberty Safe describes as a material that expands when exposed to heat. Its care advice: inspect the seal for splits, brittleness and gaps at the corners, and clean it with a soft, slightly damp cloth. Your safe's manual has the maker's own steps.

What this list leaves out, and why

• Gun safes with no stated duration. A fire claim without minutes can't be sorted or compared.
• Ratings under 45 minutes. They appear on the full fire-rated gun safes table.
• Handgun safes and cabinets. The rule covers gun safes for long guns only. Check the fire column on our handgun safes table; a dash means no rating in writing.
• Safes not available on Amazon US this week. We check availability weekly and drop safes that are out.
• Amazon's own brands. Not listed anywhere on the site.

No popularity, review count or editor's score plays any part. A safe is here because its fire line passed the rule.

Read the warranty next to the fire rating

A fire rating describes a test. A warranty describes what the maker will do after a real fire. Read them together.

Several makers on this list put fire in the warranty by name. Winchester states a lifetime free replacement after a fire or burglary attack. Stealth states a lifetime burglary and fire warranty, with two years on parts and labor. Amsec states a lifetime warranty against theft and fire. Sports Afield's lifetime warranty lists theft, fire and natural flood.

Those are the makers' words, and the terms behind them are in each warranty document. Before you buy, check three things in that document:

• What it replaces. The safe, the contents, or neither. Don't assume the contents.
• What it asks of you. Registration, photos, or returning the damaged safe.
• How long "lifetime" is. Yours, the safe's, or the company's. The document says which.

A long fire claim with a warranty that names fire is a maker putting its money near its number. It's still a claim. But it's a claim with a consequence.

Who should look elsewhere

• You mostly need to protect papers. A dedicated fire-rated document box can suit paper better than a large gun safe. See fire-rated document boxes.
• You want thick steel as well as a fire claim. Our best gun safes list adds a 14-gauge-or-thicker condition.
• You want the full background. The guide are gun safes fireproof goes through every part of a fire rating, and UL safe ratings covers burglary.

Before you buy, write the fire line out as three parts. If one is missing, ask the manufacturer for it in writing. Then check the price, and bolt it down where it will stand.
