Buying a gun safe is a huge step in protecting not just your firearms, but also documents, heirlooms, and other valuables. A lot of people start shopping thinking “a safe is a safe”, but the more they look, the more they see there’s more to it than they realized.
The good news is that choosing the right safe doesn't have to be complicated. Choosing the right safe boils down to five key factors: size, steel thickness, fire protection, lock type and warranty. Understanding these basics will help you compare safes and make a more informed decision.

1. Size: How Much Room Do I Need?
What’s the biggest complaint people have about their safe? They wish they bought a bigger safe. You see this everywhere online; “I love my safe, but I wish I would’ve bought the bigger one”. While buying a safe that fits what you need right now seems logical at the time, collections grow over time.
It’s not just long guns. It’s handguns, optics, documents, jewelry, valuables like purses, heirlooms; It all piles up over time. A safe that feels spacious today can become crowded surprisingly quickly.
It's also important to understand that advertised firearm capacities are often based on storing slim rifles without optics or accessories. Modern sporting rifles, scoped hunting rifles, shotguns, and firearms with bipods or extended magazines require considerably more room than the published capacity suggests.
If you ask someone who has bought a safe what advice they’d give to a first time buyer, “go bigger” is at the top of the list. The additional space provides flexibility, makes organizing your belongings easier, and buying a larger safe now is cheaper than having to come back and buy two smaller safes.

2. Steel Thickness: How Secure Is It?
Every gun safe is built with one goal: make forced entry as difficult and time-consuming as possible. The longer it takes a thief to get inside, the greater the chance they’ll give up, be discovered, or be interrupted. Steel thickness is one of the biggest factors in burglary protection; the thicker the steel, the more difficult it is to pry open, cut through, or otherwise force entry into the safe.
Most gun safes list their body steel in either gauge or inches, depending on the manufacturer. If the steel is listed in gauge, it's important to know one simple rule:
The lower the gauge number, the thicker the steel.
For example:
- 14-gauge steel is thinner than 12-gauge steel.
- 12-gauge steel is thinner than 10-gauge steel.
- Steel may also be listed in inches, such as 3/16" or 1/4", with larger measurements indicating thicker steel.
While thicker steel generally offers greater security, it's only one part of the overall picture. The strength of the door, how the safe is reinforced, the locking mechanism, and other design features all contribute to how well a safe can resist attack, but when it comes to the physical security of the safe, it all starts with the steel thickness.

3. Fire Protection: How Much Do I Need?
If a fire happens, how well will my safe protect what's inside? The answer starts with how the safe is built. Most residential gun safes use one of two methods to provide fire protection.
The first common approach is layered fire board insulation, where specially designed fire-resistant boards are installed tightly inside the walls and door of the safe. Generally speaking, the more layers used, the greater level of fire protection.
The second method is composite construction, where a fire-resistant insulating material is placed between an inner and outer steel wall. This creates a solid insulated barrier that helps slow the transfer of heat into the safe.
In addition to the insulation itself, most gun safes include an expanding fire seal around the door. During a fire, this seal expands as temperatures rise, sealing the door and helping reduce the amount of heat and smoke that can enter through the gap.
Is more fire protection always better? Generally speaking, yes—but the amount of fire protection needed depends on your situation.
Someone living in a condominium or a neighborhood with a nearby fire station may be comfortable with a lower fire rating, since firefighters are often able to respond more quickly. Someone living in a rural area, where response times can take longer, might want higher fire protection to provide a greater margin of safety. If you'll be storing irreplaceable family documents, photographs, heirlooms, or other valuables that can't be replaced, the added protection of a higher fire rating can give you extra security, and extra peace of mind.
The goal isn't necessarily to buy the highest fire rating available—it's to choose the level of protection that best fits your home, your location, and what you're protecting.

4. Lock Type: Which One Should I Get?
Nearly every modern gun safe is available with either a mechanical dial lock or an electronic keypad lock. Both have proven themselves over many years, and each offers advantages depending on how you plan to use your safe.
Mechanical Locks
Mechanical combination locks have earned a reputation for long-term reliability. They don't require batteries and have been trusted for generations. A lot of people appreciate their simplicity and traditional design.
The tradeoff is that they generally take longer to open and require dialing the correct combination each time.
Electronic Locks
Electronic locks give you fast access and are especially popular with owners who use their safe frequently. Most allow you to change your combination without a service call, and many include additional convenience features.
These locks do require batteries, although replacing them periodically is simple preventative maintenance. Quality electronic locks from reputable manufacturers have become extremely dependable and are used on countless residential and commercial safes.
Neither lock is universally "better." The right choice depends on your personal preferences, how often you'll access your safe, and which operating style you find most comfortable.

5. Warranty: What Happens If Something Goes Wrong?
A gun safe is built to protect valuable possessions for decades, so it's worth taking a close look at what happens if something ever goes wrong.
A good warranty should cover at least these three things:
Theft
If someone attempts to break into your safe, or actually succeeds, the manufacturer should stand behind the safe with repair or replacement coverage. Be sure to check exactly what is included, since coverage for things like freight, removal, and installation can vary by manufacturer.
Fire
If the safe goes through a fire, a good warranty should provide similar protection. Look for coverage that includes replacement of the damaged safe, as well as the work necessary to open it so you can recover the contents before it’s removed.
Defects
If something mechanically fails with the safe itself, the manufacturer should cover the work necessary to get it operating properly again. This generally doesn't include cosmetic or interior items such as fabric or shelving, but the components that make the safe function should be covered.
What about the lock?
Most manufacturers offer at least some warranty. Some offer one year, some two and some offer five years on the lock. Some companies offer extended warranties that give you lifetime coverage, which we highly recommend taking advantage of. With a lifetime warranty on the lock, you now have a safe that will be covered for life.
A strong warranty isn’t just a safety net. It also tells you how willing a manufacturer is to stand behind the safes they build.

Now You Know What To Look For
Choosing the right gun safe doesn't require becoming an expert on the subject. By understanding those five key areas—size, steel thickness, fire protection, lock options, and warranty—you'll be well prepared to compare different models and ask the right questions before making your decision.
Every buyer's needs are different. The best safe for one family may not be the best choice for another. By focusing on the features that matter most to you, you'll be able to find a safe that provides the right balance of security, convenience, and long-term value.
